This is a mirror of the original BitMEX trollbox archive that used to be online here.
BitMEX disabled their archive after the DDOS attack so I have decided to make my mirror publicly available.

Well now, a few days after I made this mirror available to the public, the original archive from BitMEX is online again.
But since it is still limited (neutered to the last few hundred messages) I will keep my FULL mirror alive.

[2015-08-28 12:41:36] BitMEX_Sam : See https://www.bitmex.com/app/wallet
[2015-08-28 12:43:03] BitMEX_Sam : FYI we have now moved Bitcoin-settling contracts off Bitstamp (formerly Bitfinex) and over to TradeBlock XBX. https://tradeblock.com/markets/index/
[2015-08-28 12:43:37] ssa3512 : BitMEX_Sam: well the wallet transaction was almost -0.2 BTC
[2015-08-28 12:43:56] BitMEX_Sam : Okay. So it just turned unrealised loss into realised loss
[2015-08-28 12:44:11] ssa3512 : yes, but now my entry price is lower
[2015-08-28 12:44:23] ssa3512 : and I still am bullish for september
[2015-08-28 12:44:32] BitMEX_Sam : Well, if you're long a lower entry price is good
[2015-08-28 12:45:34] BitMEX_Sam : There's more profit between, say, 226 and 250 than between 235 and 250.
[2015-08-28 12:48:26] ssa3512 : so now that we've tested 220 again we can go up right?
[2015-08-28 12:48:27] ssa3512 : :P
[2015-08-28 12:49:25] BitMEX_Sam : If I knew that, I'd be trading, not running an exchange. :)
[2015-08-28 12:50:39] BitMEX_Sam : FYI withdrawals are processing now. If you were just after 12 UTC we included you in this batch because of the rebalance
[2015-08-28 12:50:56] BitMEX_Sam : We are considering moving the time back an hour to give users time to withdraw after rebalances - anybody have any opinions on this?
[2015-08-28 12:53:37] ssa3512 : BitMEX_Sam: I think that is a good idea
[2015-08-28 12:54:26] ssa3512 : you guys are using 2-of-3 right
[2015-08-28 12:56:06] BitMEX_Sam : Yeah multisig is used on all addresses.
[2015-08-28 12:56:44] BitMEX_Sam : That's why it has to happen manually. We'll do a hybrid hot/cold one day but it will be very limited. I consider any wallets hooked up to a webserver to be lost Bitcoin, it's just a matter of time
[2015-08-28 12:56:58] vbmithr : I'm working on a gateway between exchanges and the DTC protocol (dtcprotocol.org)
[2015-08-28 12:57:25] vbmithr : So that it is possible to trade using Sierra Chart
[2015-08-28 12:58:08] BitMEX_Sam : vbmithr: Very interesting
[2015-08-28 12:59:05] vbmithr : I'm focusing on exchanges that do margin trading / leverage
[2015-08-28 12:59:21] vbmithr : basically the ones that have a concept of position
[2015-08-28 12:59:21] BitMEX_Sam : Very happy to help, email me at sam@bitmex.com if you have questions
[2015-08-28 12:59:36] vbmithr : Thanks!
[2015-08-28 12:59:57] vbmithr : It's good that you have a testnet btw
[2015-08-28 13:00:01] vbmithr : Very few exchange have
[2015-08-28 13:00:11] BitMEX_Sam : If we consider the demand high enough we may be able to move a high-quality adapter inside the API itself and avoid the overhead of serializing to JSON and back
[2015-08-28 13:00:29] BitMEX_Sam : Yeah the testnet is absolutely necessary both for us and our integration partners.
[2015-08-28 13:00:58] BitMEX_Sam : And it helps a lot over a shared dev environment in that we can ask our users for feedback.
[2015-08-28 13:00:58] vbmithr : Most of exchanges say the same thing, not enough demand for the pain of implementing FIX or something of the sort
[2015-08-28 13:01:16] BitMEX_Sam : Yeah. We use FIX column names and built the engine with FIX in mind but we haven't gone all the way with it yet
[2015-08-28 13:01:29] vbmithr : ok!
[2015-08-28 13:01:47] vbmithr : I'm glad to know a bit on how you implement things, it's interesting
[2015-08-28 13:02:05] vbmithr : So you have a FIX core but present a REST/Websocket API on top of this ?
[2015-08-28 13:02:21] BitMEX_Sam : Essentially, the table structures are based on FIX
[2015-08-28 13:02:34] vbmithr : yeah, understand.
[2015-08-28 13:02:35] BitMEX_Sam : The trading and position keeping system is a single engine written in q (kdb+/q)
[2015-08-28 13:02:47] vbmithr : never heard of q :)
[2015-08-28 13:03:02] BitMEX_Sam : http://kx.com/software.php
[2015-08-28 13:03:59] BitMEX_Sam : We wrote a layer on top of it that emits all changes to all tables to a pub/sub system. That then does access control / bucketing and interfaces with the websocket server.
[2015-08-28 13:05:30] vbmithr : yeah I see
[2015-08-28 13:06:06] BitMEX_Sam : So in order to do DTC, as far as I understand the implementation of DTC, the hard part would be translating those realtime messages into their format
[2015-08-28 13:06:12] vbmithr : So Websocket is output only
[2015-08-28 13:06:19] BitMEX_Sam : Well, you can request table images through it
[2015-08-28 13:06:25] BitMEX_Sam : It's an easy way to get synced up
[2015-08-28 13:06:33] vbmithr : I've implemented a lot already
[2015-08-28 13:06:41] BitMEX_Sam : But you can't do orders through it - we consider the request/response model of HTTP to be a lot better suited for orders.
[2015-08-28 13:06:43] vbmithr : mmh, the hard part…
[2015-08-28 13:06:56] vbmithr : the hard part was to make an abstraction of bitcoin exchanges so that I can easily implement many of them
[2015-08-28 13:07:07] BitMEX_Sam : Ah, so you've already done a lot of generalizable work.
[2015-08-28 13:07:10] vbmithr : yes
[2015-08-28 13:07:18] vbmithr : yes (to the question)
[2015-08-28 13:07:20] BitMEX_Sam : That's great
[2015-08-28 13:07:36] BitMEX_Sam : OCaml?
[2015-08-28 13:07:36] vbmithr : I've mostly worked on Kraken/Bitfinex
[2015-08-28 13:07:41] vbmithr : Bitfinex API is not so great
[2015-08-28 13:07:42] vbmithr : yeah
[2015-08-28 13:08:03] BitMEX_Sam : Yeah we have had lots of troubles with their API.
[2015-08-28 13:08:17] BitMEX_Sam : That and the recent instability were more than enough reason to move our settlements off it.
[2015-08-28 13:08:24] vbmithr : Kraken looks very professional
[2015-08-28 13:08:33] vbmithr : apart from the no streaming api, not pro at all
[2015-08-28 13:08:41] BitMEX_Sam : Yeah Kraken does a pretty good job.
[2015-08-28 13:08:41] vbmithr : yeah I've seen that
[2015-08-28 13:09:01] vbmithr : I'm trying to work with coinsetter as well
[2015-08-28 13:09:07] vbmithr : they have a full FIX API
[2015-08-28 13:09:48] vbmithr : But I think your API is great actually
[2015-08-28 13:10:08] BitMEX_Sam : Thanks - we're going for simplicity in the REST calls and completeness in the WebSocket
[2015-08-28 13:10:24] BitMEX_Sam : It's the exact same API the frontend uses so it needed to fill those needs as well
[2015-08-28 13:10:37] vbmithr : Great because you're probably right about the request/reply for adding orders
[2015-08-28 13:10:48] BitMEX_Sam : The HTTP documentation is a bit sparse but that's because it's actually autogenerated from the live code
[2015-08-28 13:10:54] BitMEX_Sam : So it's guaranteed to be up to date
[2015-08-28 13:11:36] BitMEX_Sam : It's Swagger-compliant (http://swagger.io/) so there's a large amount of autogenerated tooling you can use for it.
[2015-08-28 13:11:49] vbmithr : yeah
[2015-08-28 13:11:50] vbmithr : nice
[2015-08-28 13:12:18] vbmithr : dealing with rest apis is not a hard part of my thing anyway
[2015-08-28 13:12:44] BitMEX_Sam : Yeah I figured. :) It's more for novice users / users looking to get up and running ASAP
[2015-08-28 13:13:41] vbmithr : Do you have very active users ?
[2015-08-28 13:13:49] vbmithr : day traders and so on
[2015-08-28 13:14:03] vbmithr : I'm trying to gauge the usefulness of my project a bit
[2015-08-28 13:14:46] BitMEX_Sam : Yeah there are a decent number of people who are trading all day and MM bots. We're not at the level of a finex or something like that, I believe our volume is just a little higher than Coinsetter
[2015-08-28 13:15:04] BitMEX_Sam : But we're expanding into new contracts and new markets soon.
[2015-08-28 13:15:55] vbmithr : I'd like to figure out the proportion of type of traders
[2015-08-28 13:16:06] vbmithr : like algorithmic trading, chart trading, mm bots, and so on
[2015-08-28 13:16:21] vbmithr : Sierra Chart is a tool for people that do chart trading
[2015-08-28 13:16:27] vbmithr : (as the name indicates)
[2015-08-28 13:16:42] BitMEX_Sam : Ah. Yes - and we've been working on supporting that through the live charts on the site as well. But it needs work.
[2015-08-28 13:17:26] vbmithr : That's were I think my project is interesting. I don't think a js charting tool can really beat a pro software like Sierra Chart
[2015-08-28 13:17:39] BitMEX_Sam : I would agree with that. JS charting has limitations.
[2015-08-28 13:17:53] vbmithr : Actually my real fear is that my project turns out to be not much interesting
[2015-08-28 13:18:00] vbmithr : because there is just no much chart traders
[2015-08-28 13:18:29] BitMEX_Sam : Hard to say where Bitcoin trading will evolve but I know a lot of users enjoy using MT4 et al
[2015-08-28 13:18:41] vbmithr : I mean, if almost no bitcoin exchanges made a decent interface to a trading software is probably lack of demand
[2015-08-28 13:18:53] BitMEX_Sam : Once they take the plunge and try it, they seem to be very happy to be liberated from the browser
[2015-08-28 13:19:17] vbmithr : I don't see why Forex traders would use pro software and bitcoin traders shitty interfaces
[2015-08-28 13:19:27] vbmithr : it makes no sense
[2015-08-28 13:19:30] BitMEX_Sam : I think we're still waiting for those markets to coalesce
[2015-08-28 13:19:44] BitMEX_Sam : Bitcoin trading is still in its infancy
[2015-08-28 13:20:23] vbmithr : yeah
[2015-08-28 13:20:25] vbmithr : definitely
[2015-08-28 13:21:01] vbmithr : I'm gonna do my little pet project no matter what and I'll see
[2015-08-28 13:21:21] BitMEX_Sam : Yeah, and we're happy to help in any way we can.
[2015-08-28 13:21:28] BitMEX_Sam : Always interested in getting more tools hooked up to our data.
[2015-08-28 13:21:32] vbmithr : I plan to release it a DTC service, basically, it'll be integrated into Sierra Chart
[2015-08-28 13:21:54] vbmithr : So that means people passing orders will pass orders to me first and I'll forward it to you
[2015-08-28 13:22:12] vbmithr : Oh, the other big issue with my project
[2015-08-28 13:22:23] vbmithr : If exchanges directly implement DTC it becomes pointless
[2015-08-28 13:22:41] vbmithr : I would do this if I were you :)
[2015-08-28 13:22:55] vbmithr : Implementing dtcprotocol.org is _not_ that much work
[2015-08-28 13:22:57] BitMEX_Sam : So you are planning on running a service (paid or otherwise) that serves as a bridge?
[2015-08-28 13:22:57] vbmithr : for you
[2015-08-28 13:23:06] vbmithr : and the return on investment can be unbounded
[2015-08-28 13:23:10] vbmithr : yeah exacatly
[2015-08-28 13:23:30] BitMEX_Sam : Yeah understood. Then the business model is solely reliant on exchanges not wanting to do that for themselves.
[2015-08-28 13:23:38] vbmithr : a flat month fee, for the business model, not so much
[2015-08-28 13:24:26] vbmithr : Yeah but that's the issue with my project
[2015-08-28 13:24:39] vbmithr : If it happens to be successful, exchanges would immediately implement DTC
[2015-08-28 13:24:55] BitMEX_Sam : Right
[2015-08-28 13:25:17] BitMEX_Sam : Well, it might work better than you think - there is a lot of inertia in most exchanges
[2015-08-28 13:25:25] BitMEX_Sam : Evidenced by how few new features most have released in the past year
[2015-08-28 13:25:26] vbmithr : Yeah that's the thing
[2015-08-28 13:25:52] vbmithr : it seems that developing systems is harder than one imagine
[2015-08-28 13:26:03] BitMEX_Sam : The complexity eats many teams alive
[2015-08-28 13:26:44] vbmithr : Same for me, except that I'm the only one in the team :)
[2015-08-28 13:27:28] vbmithr : I'm gonna integrate you in my bridge, I'll give you updates
[2015-08-28 13:27:51] BitMEX_Sam : Sure - happy to help
[2015-08-28 13:31:38] ssa3512 : BitMEX_Sam: I have to say the open order rollup and button to cancel all buys/sells is a great feature
[2015-08-28 13:32:31] BitMEX_Sam : ssa3512: Glad to hear it, we found it very useful in testing.
[2015-08-28 13:40:57] vbmithr : The ws interface is really cool :)
[2015-08-28 13:41:08] vbmithr : I think you are maybe the best API in the whole exchange world :)
[2015-08-28 13:41:12] vbmithr : (bitcoin exchanges)
[2015-08-28 13:42:00] BitMEX_Sam : vbmithr: Thanks
[2015-08-28 14:18:19] ilikepies69 : BitMEX_Sam: Hi, I can't seem to find your charts on tradingview, can you please provide links?
[2015-08-28 14:19:04] BitMEX_Sam : ilikepies69: Try https://www.tradingview.com/chart/SMJEhYRR/
[2015-08-28 14:19:15] BitMEX_Sam : If you start typing `bitmex` in the search box some should show up
[2015-08-28 14:19:28] BitMEX_Sam : Unfortunately it's not all, and occasionally the data disappears. Not sure what is going on, on their end - not an issue on our side
[2015-08-28 14:19:52] ilikepies69 : it seys invalid symbol
[2015-08-28 14:20:56] ilikepies69 : I tried searching, nothing comes up either
[2015-08-28 14:21:09] BitMEX_Sam : Really
[2015-08-28 14:21:23] BitMEX_Sam : I wonder if they have a data sync issue, because I've heard others tell me this
[2015-08-28 14:21:34] BitMEX_Sam : Maybe if you're connected to one server you see it, and the other you don't
[2015-08-28 14:21:50] BitMEX_Sam : Try searching `XBTU2015`
[2015-08-28 14:25:23] ilikepies69 : very bizarre, clicked on link again and it appears and made chart mine, also xbu & xbt appears
[2015-08-28 14:25:42] ilikepies69 : but still nothing if i search bitmex
[2015-08-28 14:26:46] BitMEX_Sam : Yeah that's quite strange.
[2015-08-28 14:29:04] ilikepies69 : and now its gone - invalid symbol & nothing on search
[2015-08-28 14:29:13] ilikepies69 : cloak activated
[2015-08-28 15:15:28] SnackyCoins : What sort of thing would cause "pending" affiliate turnover to not confirm?
[2015-08-28 15:17:53] BitMEX_Sam : SnackyCoins: It's rolled over every day at 12 UTC
[2015-08-28 15:18:02] BitMEX_Sam : Did you see pending awards that didn't roll?
[2015-08-28 15:18:19] SnackyCoins : Yeah i saw 17.something in pending yesterday
[2015-08-28 15:18:26] SnackyCoins : (in turnover)
[2015-08-28 15:18:41] BitMEX_Sam : Ah. Let me look into it and get back to you
[2015-08-28 15:18:54] SnackyCoins : thanks :)
[2015-08-28 15:19:51] SnackyCoins : i realize the payment wont move during no-fee month :)
[2015-08-28 15:29:39] TInvest : have we moved over to non-insanity land yet?
[2015-08-28 15:29:45] ssa3512 : yep
[2015-08-28 15:29:49] TInvest : oh
[2015-08-28 15:29:50] ssa3512 : settling on XBX
[2015-08-28 15:29:50] TInvest : my
[2015-08-28 15:29:59] TInvest : nooddley apendage
[2015-08-28 16:32:34] vanillafan : hi
[2015-08-28 16:46:24] cryptojoe : Those alert tones are so satisfying.
[2015-08-28 18:25:35] cryptojoe : Anybody else losing real time connection or am i just running too many things at once at my end?
[2015-08-28 18:25:52] BitMEX_Sam : I haven't seen any issues here
[2015-08-28 18:26:20] cryptojoe : have about 8 charts and/or orderbooks opened so it's prob me
[2015-08-28 18:27:07] ssa3512 : cryptojoe: haven't seen any issues here
[2015-08-28 18:31:42] laisee : i lose connection and have to login every 15 mins or so. probably down to my internet connection tho..
[2015-08-28 18:55:06] gustavo7 : wow someone dumped on XBTU15
[2015-08-28 18:55:41] j8 : yeah got nice fills there!
[2015-08-28 18:55:53] cryptojoe : me too . yeh!
[2015-08-28 18:56:03] j8 : more plz
[2015-08-28 18:56:25] cryptojoe : my tones aren't working i diddn't even notice
[2015-08-28 19:02:38] j8 : is there sound now? didn't realize
[2015-08-28 19:04:19] cryptojoe : sometimes it seems to be working and i get a pleasant tone when there is a fill. then i salivate like Pavlov's dog
[2015-08-28 19:06:09] j8 : lol
[2015-08-28 19:06:43] cryptojoe : okcoin seems to be pushing for a dump
[2015-08-28 19:07:39] j8 : they're pretty bearish the last couple days. had a nice arb last night that worked out
[2015-08-28 19:08:03] j8 : on quarterlies
[2015-08-28 19:11:45] ssa3512 : can someone please explain the woodchipper to me
[2015-08-28 19:12:07] ssa3512 : I've heard it mentioned a few times
[2015-08-28 19:12:50] cryptojoe : ssa3512: whenever you try to type in the name of that exchange that has the highest the chat automatically converts it to okcoin
[2015-08-28 19:13:21] ssa3512 : erm
[2015-08-28 19:13:26] ssa3512 : the highest volume?
[2015-08-28 19:13:29] cryptojoe : I wonder if it works for other exchanges like bitstamp, bitfinex, Houbi or btcChina
[2015-08-28 19:13:34] cryptojoe : nope
[2015-08-28 19:13:41] ssa3512 : OkCoin?
[2015-08-28 19:13:44] ssa3512 : ha
[2015-08-28 19:13:47] cryptojoe : The one that begins with ok
[2015-08-28 19:13:52] ssa3512 : yeah okcoin
[2015-08-28 19:14:01] cryptojoe : exactly okcoin
[2015-08-28 19:14:11] j8 : the fucking okcoin
[2015-08-28 19:14:12] cryptojoe : so funny
[2015-08-28 19:14:19] ssa3512 : why does it change ok coin to the woodchipper
[2015-08-28 19:15:03] cryptojoe : Maybe it's like when mafia kill their own, they say, "Never mention his name again" id on't know
[2015-08-28 19:15:52] j8 : just the confuse the fuck out of people
[2015-08-28 19:16:40] ssa3512 : wat
[2015-08-28 19:16:56] ssa3512 : is that what shit is changed to?
[2015-08-28 19:17:04] ssa3512 : gently caress?
[2015-08-28 19:17:10] ssa3512 : I'm very confused
[2015-08-28 19:17:13] gustavo7 : now you know
[2015-08-28 19:17:28] gustavo7 : i'm gonna fuck you gently
[2015-08-28 19:18:01] gustavo7 : (tenacious d)
[2015-08-28 19:18:54] gustavo7 : but think i read woodchipper on bitcoinmarkets before, because some weeks ago it had these attack and really choppy movements rekting everyone
[2015-08-28 19:18:54] cryptojoe : fuck
[2015-08-28 19:19:00] cryptojoe : i guessed it
[2015-08-28 19:19:31] j8 : yeah, woodchipper has been a bit of a meme for okc
[2015-08-28 19:21:06] j8 : 20x gamblers are the wood, colocated MM's are the woodchipper
[2015-08-28 19:24:59] ssa3512 : man xbtu dropped
[2015-08-28 19:26:40] gustavo7 : someone betting for the full retrace of this little pump and some more
[2015-08-28 19:26:55] BitMEX_Sam : This is where it comes from: http://i.imgur.com/t0Pw9AN.png
[2015-08-28 19:29:29] ssa3512 : ha
[2015-08-28 19:29:45] j8 : proxied now?
[2015-08-28 19:30:01] BitMEX_Sam : j8: No, we haven't implemented that, but only admins can post images
[2015-08-28 19:30:13] BitMEX_Sam : I didn't mean to use it so I've edited the message to just be a link
[2015-08-28 19:30:23] BitMEX_Sam : I might just rip it out entirely so none of us accidentally post one
[2015-08-28 19:30:58] ssa3512 : BitMEX_Sam: not sure if bug or not but I can isolate margin on a position of size 0 and margin changes to NaNx
[2015-08-28 19:31:11] ssa3512 : no idea what that would do if my orders filled
[2015-08-28 19:31:27] BitMEX_Sam : ssa3512: 99.9% of the time, that's a display bug
[2015-08-28 19:31:33] BitMEX_Sam : The engine is very well tempered. I'll take a look
[2015-08-28 19:31:57] ssa3512 : well, there is technically 0 margin right now because it's unfilled
[2015-08-28 19:32:20] BitMEX_Sam : Ahhhh.
[2015-08-28 19:32:26] BitMEX_Sam : Makes perfect sense. Thanks
[2015-08-28 19:32:35] BitMEX_Sam : That's what happens when you divide by `0` :)
[2015-08-28 19:32:58] ssa3512 : well yeah but what would happen if the order filled
[2015-08-28 19:33:09] ssa3512 : because when you lock margin at 0 and all of a sudden have a position
[2015-08-28 19:33:12] ssa3512 : rekt
[2015-08-28 19:33:20] BitMEX_Sam : It's just a display bug. You would be isolated at 25x when it filled.
[2015-08-28 19:33:29] ssa3512 : ah
[2015-08-28 19:33:44] BitMEX_Sam : On the backend that toggles a flag on/off called `crossMargin` that tells the engine whether or not to use your full margin balance or not to back the position.
[2015-08-28 19:34:00] ssa3512 : gotcha
[2015-08-28 19:51:12] j8 : BitMEX_Sam: i'm trying to find some `.XBT_5M` data referenced to tradeblock, for pricing `BVOL`, does the data in the api switch over at today's settlement? i think i remember hearing you guys were collecting it the last few weeks, is that available anywhere?
[2015-08-28 19:51:50] BitMEX_Sam : j8: It changed already at 12 GMT. I don't know if we have an archive of it from before, let me see if I can find one.
[2015-08-28 19:52:06] j8 : cool.
[2015-08-28 19:52:37] BitMEX_Sam : For now you might get some mileage out of the 1H data at https://tradeblock.com/markets/index/
[2015-08-28 19:53:01] BitMEX_Sam : I believe our testnet server was collecting XBX data for the last two weeks but I'm not 100% sure.
[2015-08-28 19:58:38] j8 : some weird stuff in the testnet data from today. went to 265, went back in time...
[2015-08-28 20:00:33] j8 : showing on the site anyway, not in the api
[2015-08-28 20:00:46] j8 : oh wait yeah it is.
[2015-08-28 20:05:26] BitMEX_Sam : Yeah I see that too. Will have Wally check it out
[2015-08-28 20:06:22] ssa3512 : BitMEX_Sam: any thoughts on non-bitcoin futures?
[2015-08-28 20:06:32] BitMEX_Sam : Non-crypto or just non-bitcoin?
[2015-08-28 20:06:45] ssa3512 : was thinking XAU futures
[2015-08-28 20:07:06] BitMEX_Sam : Ah yes. Yeah, legality and liquidity permitting.
[2015-08-28 20:07:14] cengel : sam which channel is the XBX stream
[2015-08-28 20:07:47] BitMEX_Sam : cengel: All our our Bitcoin indices, so `.XBT`, `XBT_5M` are the main ones
[2015-08-28 20:07:57] BitMEX_Sam : Sorry that second one is `.XBT_5M`
[2015-08-28 20:09:10] BitMEX_Sam : ssa3512: Fixed the `NaN` in the leverage readout you were seeing, a refresh will fix it
[2015-08-28 20:10:30] ssa3512 : nice
[2015-08-28 20:10:41] ssa3512 : you guys are awesome
[2015-08-28 20:11:31] ssa3512 : hoping more people ditch okcoin and bitfinex
[2015-08-28 20:11:40] ssa3512 : get some more volume going on
[2015-08-28 20:12:02] cryptojoe : looks like bitfinex dropped to 5th in volume
[2015-08-28 20:12:05] BitMEX_Sam : http://i.imgur.com/I8CGaLh.gif
[2015-08-28 20:12:19] BitMEX_Sam : Ok let me fix that too.
[2015-08-28 20:12:35] ssa3512 : lol what is going on there
[2015-08-28 20:13:35] cryptojoe : that is one disturbing gif
[2015-08-28 20:13:48] BitMEX_Sam : He's a disturbing man.
[2015-08-28 20:14:38] ssa3512 : BitMEX_Sam: someone needs to fill my bid on XBTU15_Z15
[2015-08-28 20:16:13] j8 : that's a troll bid
[2015-08-28 20:16:21] BitMEX_Sam : :) Good luck with that one
[2015-08-28 20:16:33] ssa3512 : the fact that you can bid 0 is pretty funny to me
[2015-08-28 20:16:40] BitMEX_Sam : You can bid negative if you like
[2015-08-28 20:16:45] BitMEX_Sam : It makes sense on calendar spreads.
[2015-08-28 20:17:14] ssa3512 : yeah well I gues
[2015-08-28 20:17:28] BitMEX_Sam : Not that I would expect a negative bid ever to get filled, would have to be one heck of a bearish market.
[2015-08-28 20:17:28] ssa3512 : except nobody is gonna fill it
[2015-08-28 20:17:35] j8 : i'm outbidding you.
[2015-08-28 20:19:06] ssa3512 : there we go
[2015-08-28 20:19:11] ssa3512 : serious bid
[2015-08-28 20:19:11] BitMEX_Sam : Hah
[2015-08-28 20:19:51] BitMEX_Sam : Just eats up initMargin.
[2015-08-28 20:19:56] ssa3512 : yeah
[2015-08-28 20:20:32] j8 : BitMEX_Sam: what price does it reference to if it fills? mark price on `XBTU15`?
[2015-08-28 20:21:31] BitMEX_Sam : Yeah.
[2015-08-28 20:21:32] BitMEX_Sam : See https://www.bitmex.com/app/lesson3
[2015-08-28 20:21:45] BitMEX_Sam : Our good friend Johnny learns to trade
[2015-08-28 20:21:58] BitMEX_Sam : Hah we have to find a way to make that less condescending.
[2015-08-28 20:22:17] BitMEX_Sam : Hope it's helpful
[2015-08-28 20:22:29] j8 : is it possible to end up with a negative price on one leg?
[2015-08-28 20:23:06] BitMEX_Sam : If you could find anyone crazy enough to fill that, I don't believe it would actually execute. Let me try it on my development machine
[2015-08-28 20:23:44] ssa3512 : you mean the negative 150?
[2015-08-28 20:24:21] j8 : negative spread is no problem, i'm thinking if it was so negative that one of the contracts you end up with has negative entry price
[2015-08-28 20:24:48] BitMEX_Sam : Yeah. So I suppose that would be any price < 238.15
[2015-08-28 20:27:38] j8 : just trying to avoid the universe imploding :)
[2015-08-28 20:30:04] cryptojoe : ether trade seems to be grinding to a trickle
[2015-08-28 20:30:24] ssa3512 : yeah I noticed that too
[2015-08-28 20:31:42] cryptojoe : i'm sure it will pick up again when they launch a user friendly client
[2015-08-28 23:50:41] cryptojoe : Funny how stamp and finex are dragging while china is crashing
[2015-08-29 00:40:37] zanza : mm
[2015-08-29 00:40:51] zanza : okcoin has biggest volum,e i think
[2015-08-29 00:41:36] zanza : :)
[2015-08-29 03:10:19] zanza : we got some volume on XBTZ15
[2015-08-29 03:36:36] cryptojoe : stamp not following the price into okcoin
[2015-08-29 03:37:28] cryptojoe : I could make much more money if the markets were rational
[2015-08-29 03:56:54] zanza : ^ lol
[2015-08-29 04:00:45] cryptojoe : sell pressure is high in the woodchipp
[2015-08-29 04:01:31] Matthew.v : hidden valley buy the dip
[2015-08-29 04:02:16] j8 : whats a hidden valley
[2015-08-29 04:02:42] cryptojoe : volume at stamp and finex is almost non-existent. that's scary
[2015-08-29 04:03:27] Matthew.v : http://imgur.com/JgGaBIL
[2015-08-29 04:03:36] Matthew.v : buy the dip
[2015-08-29 04:03:45] j8 : lol
[2015-08-29 04:03:51] j8 : i see
[2015-08-29 04:04:20] j8 : this dip is not on sale
[2015-08-29 04:05:36] j8 : i don't pay full price for ranch.
[2015-08-29 04:05:55] Matthew.v : always buy the dip on bitcoin
[2015-08-29 04:06:06] cryptojoe : the smell of ranch makes me ill
[2015-08-29 04:07:10] j8 : more of a mayo person myself.
[2015-08-29 04:07:30] Matthew.v : miracle whip folk should die slowly
[2015-08-29 04:13:30] cryptojoe : Matthew.v: i'm gonna be sick
[2015-08-29 07:47:46] joequant : anyone know if a good algo trading engine that works with bitcoin. I've been thinking about taking zipline and interfacing it with bitmex.
[2015-08-29 10:03:43] lolcookie : any good trades atm
[2015-08-29 10:03:54] lolcookie : cant find anythign decent on the books
[2015-08-29 10:05:27] lolcookie : guess ill sit on my hands for a bit
[2015-08-29 13:20:27] vbmithr : Hi there
[2015-08-29 13:20:52] vbmithr : How do I do to get historical price data (trades) for bitmex ?
[2015-08-29 13:45:27] vbmithr : I started working on a DTC -> BitMEX fast prototype
[2015-08-29 13:45:43] vbmithr : It's going to be the first supported exchange :)
[2015-08-29 13:49:12] TInvest : what's going on - is everyone asleep?
[2015-08-29 13:55:47] BitMEX_Wally : vbmithr: Check out our API: https://www.bitmex.com/api/explorer/
[2015-08-29 13:57:11] BitMEX_Wally : TInvest: It's 10pm on a Saturday night for us (Hong Kong time)
[2015-08-29 13:57:37] TInvest : it's midnight for us here in east coast Australia
[2015-08-29 13:57:49] TInvest : i guess I'm a nighttime day trader
[2015-08-29 13:58:37] vbmithr : BitMEX_Wally: I'd like to get all of them though
[2015-08-29 13:58:55] vbmithr : BitMEX_Wally: thanks anyway.
[2015-08-29 14:03:00] BitMEX_Wally : vbmithr: Let me know what you need
[2015-08-29 14:06:45] vbmithr : All trades since inception
[2015-08-29 14:06:52] vbmithr : But I'm gonna fetch them using the REST API
[2015-08-29 14:06:58] vbmithr : Since they are available.
[2015-08-29 14:07:02] vbmithr : So, nothing at all :)
[2015-08-29 14:07:24] BitMEX_Sam : vbmithr: Yep, they're all there, you just have to fetch them in buckets of 500 and stay under the ratelimit
[2015-08-29 14:07:31] BitMEX_Sam : Morning, by the way
[2015-08-29 14:07:37] vbmithr : :) morning!
[2015-08-29 14:07:59] vbmithr : It would be awesome if you could provide flat files with trades in there
[2015-08-29 14:08:33] BitMEX_Sam : Yeah, something like a monthly CSV export isn't a bad idea at all.
[2015-08-29 14:08:38] vbmithr : yes
[2015-08-29 14:11:07] vbmithr : starting point for results, it is indexed in what ?
[2015-08-29 14:11:09] vbmithr : id ?
[2015-08-29 14:11:14] vbmithr : if I put 0, I get the first trades ?
[2015-08-29 14:12:22] vbmithr : yep.
[2015-08-29 14:14:19] BitMEX_Sam : vbmithr: Yep, starting from the very beginning. If you send `reverse=true` you'll get them starting from the end
[2015-08-29 14:14:38] BitMEX_Sam : So you could easily grab the last month of data by just paging backwards until the timestamps are where you want
[2015-08-29 14:15:28] vbmithr : Yeah, I see.
[2015-08-29 14:22:34] vbmithr : How does it work if I ask for all the symbols
[2015-08-29 14:22:52] vbmithr : The start,count is still relevant in this case…
[2015-08-29 14:22:57] vbmithr : (obviously)
[2015-08-29 14:23:01] vbmithr : I'm gonna do this
[2015-08-29 14:32:57] vanillafan : hi
[2015-08-29 14:35:07] BitMEX_Sam : Hey vanillafan
[2015-08-29 14:35:19] vanillafan : hi, :)
[2015-08-29 17:23:50] j8 : `XBTU15_Z15` broken?
[2015-08-29 21:39:39] ssa3512 : j8: looks that way
[2015-08-29 21:54:28] BitMEX_Sam : Looking into it
[2015-08-30 03:44:54] johnny : lol, its so very "calm" here
[2015-08-30 03:46:07] BitMEX_Arthur : Sunday funday
[2015-08-30 03:53:14] johnny : haha
[2015-08-30 06:22:34] zanza : whales swooping in ?
[2015-08-30 06:25:31] j8 : no volume
[2015-08-30 06:25:51] BitMEX_Arthur : Price has flatlined
[2015-08-30 07:51:36] BitMEX_Arthur : Anyone alive out there
[2015-08-30 07:57:19] cengel : yea
[2015-08-30 07:57:34] cengel : Arthur how do i subscribe to XBX live changes in the websocket
[2015-08-30 08:01:23] cengel : Or is the 1 minute snaps as real time as it will get
[2015-08-30 08:04:44] BitMEX_Arthur : You can go to tradeblock to subscribe the their websocket
[2015-08-30 08:04:49] BitMEX_Arthur : we provide only minutely for now
[2015-08-30 08:10:12] cengel : how come bitcoin and litecoin have ISO standard X prefix but not ETH
[2015-08-30 08:13:22] BitMEX_Arthur : Easier to understand
[2015-08-30 08:43:37] DunningKruger : cengel: because it's new I guess.
[2015-08-30 12:09:34] SnackyCoins : does tradeblock supply a public /free price api? google cant seem to find it
[2015-08-30 12:10:20] SnackyCoins : i'd like to track it on bitfx.info for mex users 8)
[2015-08-30 12:58:16] cengel : cant find either. id
[2015-08-30 14:38:44] cengel : if Sam is around maybe he can help?
[2015-08-30 14:44:21] cengel : even if there was reliable historical data i could try to reverse engineer the weightings
[2015-08-30 14:44:24] BitMEX_Sam : cengel: SnackyCoins: You can likely get a hook into their WS feed if you contact them, I believe they are being more liberal with keys now but I am not 100% on that
[2015-08-30 14:44:33] BitMEX_Sam : They export hourly CSV data yo ucould use.
[2015-08-30 14:44:40] BitMEX_Sam : We are working on publishing weightings too.
[2015-08-30 14:45:13] cengel : when i contacted them they just said you guys would have it
[2015-08-30 14:45:28] BitMEX_Sam : We'll see what we're allowed to do. We'd like to be able to republish the realtime data with weightings via the WS
[2015-08-30 14:45:37] BitMEX_Sam : I don't know if we could offer history but we may be able to provide realtime
[2015-08-30 14:47:19] cengel : the csv data is limited to the time period there
[2015-08-30 14:47:55] cengel : their weekly goes back to 2014 summer
[2015-08-30 14:48:05] BitMEX_Sam : It also appears they are publishing the data publicly via the WS on the XBX page
[2015-08-30 14:48:18] cengel : I couldnt quite figure that out though
[2015-08-30 14:49:58] cengel : for me realtime is more important than the historical
[2015-08-30 14:51:12] BitMEX_Sam : It appears they have no issue with publishing that data to the public if you see your browser connecting to the WS on that page
[2015-08-30 14:51:14] BitMEX_Sam : So that may be a good option
[2015-08-30 14:56:50] cengel : Im not seeing anything in devtools under Networks->Websockets
[2015-08-30 14:57:06] BitMEX_Sam : cengel: Usually you have to refresh it again once that's open
[2015-08-30 14:57:26] cengel : doh :)
[2015-08-30 14:58:07] cengel : Snacky: wss://socketbc.tradeblock.com/
[2015-08-30 14:58:13] cengel : ok
[2015-08-30 14:58:39] BitMEX_Sam : hmm that's odd
[2015-08-30 14:58:46] BitMEX_Sam : Our url scraper must have filtered that out, not intentional
[2015-08-30 14:58:51] BitMEX_Sam : wss://socketbc.tradeblock.com/
[2015-08-30 14:58:56] BitMEX_Sam : :(
[2015-08-30 14:59:16] BitMEX_Sam : wss:// socketbc.tradeblock.com/
[2015-08-30 14:59:57] cengel : yes
[2015-08-30 15:00:13] cengel : but that gives you the stream of the whole lot. have to filter for the market that is XBX but cant find what exact string is
[2015-08-30 15:00:30] cengel : narrowing down now sec
[2015-08-30 15:01:01] BitMEX_Sam : ` < {"time":1440946846,"pair":"XBT/USD","market":"IXBX","price":228.47,"size":0,"currency":"USD","type":2}`
[2015-08-30 15:01:12] BitMEX_Sam : You have to send it `ixbx-xbt-usd` when it starts up to get that added to your feed
[2015-08-30 15:04:17] cengel : yea this will do
[2015-08-30 15:04:20] cengel : ty
[2015-08-30 15:48:49] cryptojoe : darn. wish the last two days of free trading had more. has definitely been really fun. glad i checked this site out.
[2015-08-30 15:49:10] cryptojoe : more volume
[2015-08-30 15:53:02] BitMEX_Sam : cryptojoe: Glad you're enjoying it here
[2015-08-30 15:53:54] cryptojoe : been meaning to trade here for a while but the new found volatility was the clincher
[2015-08-30 15:54:56] BitMEX_Sam : Yeah volatility in the last few weeks has been great.
[2015-08-30 17:26:49] vbmithr : Hi bitcoiners
[2015-08-30 17:28:09] vbmithr : I can release a DTC data feed almost immediately if it can be of interest for anybody here
[2015-08-30 17:28:25] vbmithr : I'm gonna see this with the Sierra Chart team very soon
[2015-08-30 18:06:42] krtek.net : Hunting uraninite with friends is such fun.
[2015-08-30 18:07:45] vbmithr : sounds like you talk about hunting aliens in another planet
[2015-08-30 18:07:47] vbmithr : yaeh, sounds fun
[2015-08-30 18:07:48] krtek.net : Be a member of hackerspace, acquire cancer :)
[2015-08-30 18:08:45] krtek.net : No aliens, our shit is real, about 40 kilos brutto in 2 days, I estimate we can get about 200 gram of uranium from that )
[2015-08-30 18:10:28] krtek.net : http://nat.brmlab.cz/phtagr/explorer/view/category:Geovylet%20Pribram%202015-08
[2015-08-30 18:11:16] krtek.net : I'm the one with the rasta hat :)
[2015-08-30 18:27:48] vbmithr : cool :)
[2015-08-30 18:28:02] vbmithr : you want to make a a-bomb in your garage ?
[2015-08-30 18:47:29] krtek.net : well... let says, that yes, we want. but we also understand, that we are not able to collect enough material from the self-sustained chain-reaction :)
[2015-08-30 18:52:53] krtek.net : but there are other thinks that you can do with it... eg. uranite in a cloud chamber makes a great eye candy for the visitors :) An we also have some thing that are mostly not shown to normal visitors...
[2015-08-30 18:54:13] krtek.net : ... I'm still trying to make our betatron work. *wink* *wink*
[2015-08-30 19:06:01] vbmithr : :))
[2015-08-30 19:06:21] vbmithr : Cool projects
[2015-08-30 19:06:30] vbmithr : You're in Praha ?
[2015-08-30 19:12:51] krtek.net : yep.
[2015-08-30 19:13:25] vbmithr : I have a friend living there, nice city.
[2015-08-30 19:14:01] vbmithr : There is a Rihanna clip that has been filmed there :) the one of the diamond song :)
[2015-08-30 19:14:47] vbmithr : no not diamond, this! https://www.youtube.com/watch?v=yd8jh9QYfEs
[2015-08-30 19:15:14] vbmithr : the taxi has been imported, but the place is definitely Praha :)
[2015-08-30 19:19:21] krtek.net : Most probably. Kolonada waffles and Vodafone logo. Can be Praha. I'm not able to watch more than a half of that... and there was nothing more to guess from in the first part.
[2015-08-30 19:19:47] krtek.net : But there are some "diamonds" filmed here.
[2015-08-30 19:19:58] vbmithr : lol :)
[2015-08-30 19:20:08] vbmithr : yeah :)
[2015-08-30 19:20:08] krtek.net : Like Eurotrip movie... was almost completelly filmed here
[2015-08-30 19:20:12] vbmithr : that's just the first part
[2015-08-30 19:20:15] krtek.net : even the "Bratislava part" :D
[2015-08-30 19:20:47] krtek.net : https://www.youtube.com/watch?v=1mYqY5YELd0
[2015-08-30 19:20:52] vbmithr : Praha has probably sex appeal or something
[2015-08-30 19:21:05] vbmithr : what's the point of importing a NYC taxi there lol
[2015-08-30 19:22:31] krtek.net : Well... czech taxis are not required to be "yellow cabs"
[2015-08-30 19:22:33] vbmithr : "we're in eastern europe"
[2015-08-30 20:43:28] krtek.net : Until the next rain comes, we wouldn't need to turn the lights on at the backyard :D https://www.youtube.com/watch?v=DYQzPI8frR4
[2015-08-30 21:39:53] vbmithr : Ha, by the way!!
[2015-08-30 21:39:57] vbmithr : BitMEX team
[2015-08-30 21:40:16] vbmithr : Could you release a version of the websocket API without the websocket framing
[2015-08-30 21:40:35] vbmithr : i.e. dump the same messages in a plain TCP connection
[2015-08-30 21:41:19] vbmithr : It's super easy to do for you
[2015-08-30 21:42:27] vbmithr : I mean, if it is indeed super easy for you, you should provide it
[2015-08-30 21:42:46] vbmithr : websocket is an additional complexity when you don't code an app that lives in a browser
[2015-08-30 21:43:10] vbmithr : and the protocol adds a layer of framing that makes the thing a bit less efficient
[2015-08-30 21:44:07] vbmithr : while you're at it you could even use something more efficient than json too :) but I'm asking too much :p
[2015-08-30 21:44:24] vbmithr : (but still, same messages over plain TCP would be awesome IMO)
[2015-08-31 00:02:18] TInvest : bam
[2015-08-31 00:02:33] BitMEX_Arthur : http://www.coindesk.com/uk-banking-giant-barclays-to-allow-charities-to-accept-bitcoin/
[2015-08-31 00:02:40] BitMEX_Arthur : Giddy Up
[2015-08-31 00:04:38] johnny : http://www.econotimes.com/Mozilla-study-shows-bitcoin-negatively-impacts-donations-78862
[2015-08-31 00:05:11] johnny : In light of that report, barklay's move proves banks are mostly insane
[2015-08-31 00:05:39] BitMEX_Arthur : johnny: Who cares if charities receive more money or not, barclays has said it actually bought bitcoin around 230
[2015-08-31 00:06:36] johnny : Oh? I wasn't aware of that, then that is pump time then!
[2015-08-31 00:22:10] TInvest : giddy up indeed Arthur
[2015-08-31 00:23:49] TInvest : and charities accepting bitcoin is a pretty brilliant idea - when you think of the amount of dust people end up left with if they're occasional dabblers - 0.00001 don't mean much - but a whole bunch of them... well that means almost something heh
[2015-08-31 00:46:01] johnny : I agree that it is a great idea, something like changetip is goign to make that a real thing
[2015-08-31 00:46:41] johnny : But its interesting how bitcoin has real brand issues, to the point were mainstream donors dont want to donate online when there is bitcoin as a paymetn option
[2015-08-31 00:46:55] johnny : We have a lot of work to do regarding advocacy etc
[2015-08-31 02:42:45] TrevinHofmann : BitMEX_Sam: Can I ask what you use for a database infrastructure? Is there one single server with a database, or do you have multiple nodes using something like Cassandra?
[2015-08-31 02:48:35] krtek.net : I think the "db" here is redis.
[2015-08-31 04:27:51] zanza : Do you guys ever plan to offer like SP500/Oil/Gold/Forex or anything like that?
[2015-08-31 04:32:04] krtek.net : I cannot speak for the 'mex, but anything that can be indexed, could be traded as futures contracts..
[2015-08-31 04:34:49] krtek.net : Eg. there are futures on reaching the Bitcoin XT's consensus by the end of the year prepared I think :)
[2015-08-31 04:35:52] j8 : could be legal grey area, i'm not sure
[2015-08-31 04:38:39] j8 : i'm a bit surprised sites like 1broker and simplefx survive
[2015-08-31 04:39:44] krtek.net : The only thing it IMHO depends is the legal value (or valuability) of the settlement.
[2015-08-31 05:46:39] zanza : they don't want to confuse their interface by offering too many products people don't use
[2015-08-31 05:47:46] zanza : unless there is legal issues with CFD's on say, SnP500?
[2015-08-31 05:48:03] zanza : above my knowledge
[2015-08-31 05:48:26] zanza : I wanna guess though, if they settle everything in BTC then it might be OK
[2015-08-31 07:33:36] krtek.net : eth just went full retard
[2015-08-31 08:00:56] chromaticcr : still less retard than that of the first week price discovery period
[2015-08-31 08:01:47] vbmithr : what is the multiplier field in the instrument api call ?
[2015-08-31 08:05:55] BitMEX_Wally : vbmithr: It is the multiplier used to turn the quote currency (i.e. USD) into the settlement currency (i.e. XBt or Satoshi)
[2015-08-31 08:06:05] vbmithr : thanks
[2015-08-31 08:07:00] BitMEX_Wally : So you do multiplier * quantity * price to get the value of the contract in Satoshi
[2015-08-31 08:07:08] BitMEX_Wally : If the multiplier is negative you do multiplier * quantity / price
[2015-08-31 08:08:35] vbmithr : ok, my use case is to figure out the currency value per tick size
[2015-08-31 08:09:03] vbmithr : so I guess, tickSize * multiplier
[2015-08-31 08:14:02] vbmithr : would be nice to document the fields
[2015-08-31 08:14:12] vbmithr : of your API json object responses
[2015-08-31 08:16:16] BitMEX_Wally : ticksize * multiplier will only work for linear or quanto contracts
[2015-08-31 08:16:47] BitMEX_Wally : For inverse futures the Satoshi value of a tick size move in the price is a function of the price
[2015-08-31 08:18:24] vbmithr : ha yeah nonlinear derivatives
[2015-08-31 08:18:33] BitMEX_Wally : Well, they're linear in USD terms
[2015-08-31 08:18:37] BitMEX_Wally : But settled in XBT
[2015-08-31 08:19:21] BitMEX_Wally : So the XBT value is a reciprocal of the price
[2015-08-31 08:20:53] vbmithr : I think that's I'm interested in
[2015-08-31 08:21:04] BitMEX_Wally : Have a look at the XBU series
[2015-08-31 08:21:32] BitMEX_Wally : `XBUU15` is always worth 100 USD of Bitcoin
[2015-08-31 08:22:08] vbmithr : yes
[2015-08-31 08:22:42] BitMEX_Wally : So 1 contract of `XBUU15` at 200 USD has a value of -0.5 XBT
