For around 7 minutes, there has been a crossover on Intersango.  The bids at 10.00 GBP have not executed against the asks at 9.79 GBP.  What gives?

Wallet empty at a guess, sells have been close to empty all morning and there is a big increase on the charts.

What does that mean?  Whose wallet?  It's all supposed to be client funds.  If there are asks on the book, there are funds behind them, if the service is being run to spec.

It looks like everything is working as per normal other than the ask at 9.79200 not being removed.
(Bid wall is still going down from other orders.)

.... and its gone

Would it be an Intersango-glitch by any chance ? How could this come to be, I sincerely (*chuckle*) thought those guys were ominpotent.

we're all just guessing, but didn't the explanation given by stan.distortion sound satisfactory enough?

Some things (like GBP deposits) didn't work so well ;-) in the recent past, but this inicident, and the way it cleared up looks just like a sign that the platform is woking in an ordinary fashion

Read up on some of the heists at exchanges in the past. Coins to be traded are usually stored in a hot wallet with enough coins to cover the expected trades so if the exchange is compromised they don't loose everything. The bulk is stored in a cold offline wallet for security.

I don't see why the trading engine needs access to the coins.  It just needs to know how many are available.  The coins only need to be accessed when they're withdrawn.

Makes sense.

That's exactly what I am thinking....

There are no real coins on the trading part of the exchange... just a bookkeeping system: Client A trades with Client B so in our database we change the holdings of Clients A and B

Hot and cold storage wallets have got nothing to do with the actual trading.... at least they shouldn't

It's the socketio live updates.

It seems like it's from missing depth updates.

The actual trading engine never has a real problem.

Unfortunately debugging an issue I have never been able to trigger is nearly impossible.
