WTF. Just tried to place a bid in and:

Trade engine cooldown (lag too high), order placing suspended until 2013-04-13 21:00:00 UTC

The fact that they just did this was a very good thing. It is a temporary solution to a very real problem until they vastly improve their entire trading engine. We could have seen 1.5 hours of lag or more if they didn't do this. It would be stupid not to.

But after 10 minutes all the lag was gone and trading resumes in 1 minute anyway. I can totally live with brief cooldowns.

Didn't know that. Hadn't been paying attention. I always have http://bitcoinity.org/markets/mtgox/USD sitting up in a window. But I noticed that recently it no longer has the lag information posted on it like it did a day or two ago.

12 hours is different from 20 minutes. Could still go down though. They should have done this when it was at 10-15 minutes. Not 50 minutes of lag after 2.5-3 hours of horror blind trading.

This isn't to stop the price moving... or at least it shouldn't be... it should be to stop an entire market from trading BLINDLY and a momentum of panic building that will push things far more then it would have happened naturally.

You can see it on most live charts like ClarkMoody's or Bitcoinity.
In addition, this is the call to check it yourself: https://data.mtgox.com/api/1/generic/order/lag

Yeah just got on and noticed this.  Good that they're trying to manage the lag but of course we can hope they'll fix the engine sooner rather than later.

Edit - Lag's already up to 10 minutes again.

Oh Loaded, who art up in Mt. Gox, hallowed be thy name!  Thy dollars rain, thy will be done, on BTCUSD.  Give us this day our daily 10% 30%, and forgive the bears, as we have bought their bitcoins.  And lead us into quadruple digits

Nice to see they are making up fake lasts during the cooldown. Real last was 89 and they are reporting 95 to try to boost price lol

Some observations on the recent lag situation.

After ten minutes of trading since they dropped pending orders at UTC 21.00
(that's when lag went from 50 minutes to zero), lag was back up to 8 minutes 47 seconds.

From this, we can estimate that they are recieving around like 800% to 900% more orders than they can execute.

MtGox's trading engine is congested.

(This is a separate problem from the recent, ongoing DDOS attacks.)

Meanwhile, the surplus, "pending" orders get placed in a buffer.

This buffer has some finite capacity.

As long as incoming orders > 100% capacity, lag will increase without bound, tending to infinity.



This is what traffic congestion looks like, MtGox's current situation is somwhat similar.

They will have to clear the "pending orders" buffer periodically until things cool down.

Pending orders will get wiped.

Mt Gox is currently situated on the fourteenth floor of an office building, IIRC.

They need the entire building. They need something like this:



You cannot put MtGox in the cloud, for obvious reasons.

So, in a sense they're right. This "success" is killing them.

There are no easy solutions.

The situation is well and truly fucked up.

Sucks for the people who fell for the bull trap and bought in at 110+. It's not like I didn't warn them...
