Is there any hope of seeing this anytime soon.  The other day I refrained from trading because I couldn't see what I was doing due to a row of tiny, very close bids.
Depth graph is planned. Hope to see it soon too.

I don't think this should wait for a redesign.  It would be very, very useful if you could just place a link on the page to a separate page displaying the full order book. It does not need to be something fancy that autoupdates, initially just an ugly page showing a snapshot would be great.  We really need it! Smiley
Allright, tomorrow I'll add it some way or another.

There are traders who would be attracted to BUZ2 because for it provides the ability to hedge but they aren't even aware of this trading opportunity.

You should consider a way to serve the chart (and order book) for guest access (i.e., not logged in).
I think we can arrange publishing of this information through bitcoincharts.com

the futures trading chart will be live quite soon so everyone could see historical data

Well, not everyone ... only people who have registered with ICBIT and are logged in can see the charts.

These are beautiful.

Heh, that continues again and again.

Best way to buy is have some low bids in right before clearing.  Someone must feel it is better to sell a few BUZ2's right before clearing and lower the clearing price than to take the hit from a higher clearing price? (and possibly risk having their position involuntarily liquidated?)

I'm providing some liquidity to the market to narrow down the spread. This also helps stabilizing price before a clearing.

Looks like someone is hammering it right @ clearing time? Really, in the last seconds or so.

Thank you very much indeed.

No, it worked for me quite good during that time.

OK, it would have been an almost sensible thing to do, but I guess it was just a fluke - or perhaps the server gets a bit overloaded right then, when the majority of the users are on at the same time, refreshing their pages expecting to see some action.  Grin

EDIT:

PS. Did you pull the internet plug a few minutes before the clearing to prevent the usual market manipulation, or was is just me that lost connection for a few minutes at the critical time?

As for the orderbook 5 price levels limit - we are thinking on how to better place the orderbook on the trading screen and it'll be enhanced to contain more price levels once redesign is figured out.

But instead of executing my order immediately at the current best bid price (about 11.29) it looks like my order was executed at (my very low, mistaken limit price) of 10.579.

Please take a look and let me know if I am understanding the logs wrong.

You understood it right, that was the problem which was fixed. It happened only for sell orders, so all buy orders were correct anyway.

No, it's very simple. This was tested from the very beginning, however with some code changes introduced recently the wrong price was used in only one case. I fixed this yesterday and retested successfully.
A: Best buy is 11.10, best sell is 11.20. Limit order to sell a contract with a limit price of 11.00 will be executed at 11.10.
Similarly, a limit order to buy a contract with a limit price of 11.5 will be executed at 11.20.

You can test that yourself on the exchange now.

Okay, that is very good to hear, but is this a very recent change?

I was hoping that I was misinterpreting this result, but the reason I asked this question is that such a situation just happened to me the other day (by accident).

Take a look at session id 146, trade id 11 (and 12).

I intended to leave a sell limit order (above the market) at 11.579 when the current market was at about 11.29.

However, I made a mistake and accidentally typed my sell order limit at 10.579.  (Big figure mistake...this has cost me so much money over the years on all kinds of exchanges.)

Is there anyway to see more of the orderbook than five orders to each side?  Sometimes it looks like someone is (successfully!) trying to hide part of the book by placing five orders of one contract one cent apart.

It would be convenient (to say the least) to be able to see the whole orderbook for the day's trading range on the webtrade page. Only seeing the top 5 orders can make for some pretty blind trading.

agreed, this seems to be the most important shortcoming of the platform right now, especially since trading now seems to "take off".

@Fireball: are there any concrete plans  somehow "in the pipeline", regarding a full orderbook display?


BTW, this data can be retrieved through the API, but this requires some JavaScript programming, since its a streaming API, i.e. you  open an information channel and then the platform delivers messages; the client needs to sum them up to get a complete display of the current orderbook. https://icbit.se/api

Happens now since several days. Someone sells into a (comparatively) massive amount of offers at the lower end, just 5 seconds before 20:00. Maybe the intention is to squeeze other people out of their positions. Otherwise such a trading pattern doesn't make much sense IMHO. We're way below the stock rates, so to keep that situation, such a trader has to burn money every day -- and, unless the BTC rate drops significantly, those who can efford to keep a long position so comfortably below stock rates are bound to make profit, eventually Undecided

Good, it's not me seeing things Wink

Yeah, that's about my take on it. Looks like they're trying to squeeze people out, and in my case, it would have worked. I would have thought I'd have been force liquidated this week. It's not clear which would have been better(liquidation, or having the position carried). Does look like a money burning proposition, but I do note the open interest has doubled in the same time that I've noticed this pattern.

Fireball,

As you are doing some work on the site, allow me to pose this elementary but profound question:

Q: Let's say the current best bid/ask quote on a given futures contract is 11.10 - 11.20 and I enter a limit order to sell with a limit price of 11, at what price will my order be executed at?

A: On any normal limit order book market at any kind of securities exchange anywhere in the world, the answer is: 11.10
    However, on Cryptoxchange, MercadoBitcoin, the former BritCoin, and apparently ICBIT, the answer is: 11

Please do not lump yourself in with the small number of Bitcoin exchanges who do not understand how order handling is supposed to work on a limit order book and fix this.

Hi,

Also, is there a way to get all trades in the last week or so?  Or just the last 24h?  Either in human-readable form or machine readable.  Heck, it would also be OK if the full depth was JSON, not that hard to read after all.

urgs, really? That would be strange indeed.

I recall having placed such an order and allways got matched to some offers at 11.10 (according to the log entries).
What could happen indeed in such a situation is that you buy away all the offers at 11.10 and maybe one additional offer at 11.0, which makes that the last deal -- this last deal is used to calculate the unrealised loss/profit at that moment

Yup, and it looks like the 8PM tick down to 10$ passed through the bids

That $10 is bogus.  I hope nobody got forced liquidation due to an insufficient margin maintenance because of that.  

Trading range of $9 to $11, what?

@Fireball, where are these numbers coming from?

Hmm. Well, FWIW, I ran a negative balance for a few days, and just covered today. I didn't think that was how it worked, but....there you have that.

Looks like someone is hammering it right @ clearing time? Really, in the last seconds or so. I really can't work with it - looks like a 50% loss for me for the week, some due to the larger drop, but it seems more due to the clearing time changes I can't catch fast enough. I've had more than one day this week that was showing an unrealized profit on the position moments before the 20:00 clearing, and then a massive loss right after. WTF.

guruvan - if you hold big amount of contracts then even small changes in the last price introduce big changes to your unrealized profit/loss rate. It looks like some people practice to make a few deals to either try to drop or rise the price right before clearing. That does not affect the real amount of profit/loss they get, so there is little point in doing so, but they do it nevertheless Wink

Now as for the $10 problem: really sorry about that, there was a minor issue in the trading engine which saved wrong price in rare occasions. Now it's properly fixed. Extra clearing was done to get back the trading range to normal state and properly transfer the variation margin.

If you still think something is wrong - please send an email to the support address and we'll check that.
