It seems someone is making an effort to cause problems at Gox. I am waiting for my orders to be executed and the charts make no sense at all (history keeps changing).

It appears to have been real.. gox reporting 6.95 high

Actually, gox just uses a queue with timestamps.  Their order matcher can fall behind during busy times.

When the queue is busy, everyone sees huge price swings and they try to place orders, but their orders are going to the queue, not the market.  The swings you are seeing right now on mtgoxlive.com are at least several minutes old already, possibly much older, and everyone frantically clicking their trade buttons and the bots scrambling to make sense of things are just making it worse.
