Anyway, the way I see it is this - rollback means blow out every bid and offer after a certain timestamp. The last traded price is 17.50 in this case.
What about orders that were in place before that certain timestamp? That's the whole point of this thread.
The order queue will be filled once the exchange opens an hour prior to trading, with timestamps on bid/offers providing tie-breakers in case there are other orders at the same price.
Yes. The order book will fill up during the hour before trading resumes, but will the order book be empty at 03:00 GMT?
So, what this means is - any suggestion to open at a different price is invalid. It will be 17.50.
Any future 'tick' will be determined by the order book at that time, not by anything in this thread.
OK, sure. Influencing Mt Gox is not the point of this thread.
