This is why I never use their trigger orders.
Yeah, I wonder how many shorts got their positions totally wiped out on the back of this 'bug' and I wonder how long it will take Bitfinex to give people their money back.
Support has confirmed in the service discussion thread that any trades that will be rolled back have been rolled back. I personally pulled all my stops when I noticed the order book fucking up, hours before the massive fraudulent orders started pushing through. I'd be fucking pissed right now otherwise. I can't complain, I made a few thousand bucks in a few seconds. But I suspect there are many who have a right to complain. This makes leaving standing stops on Bitfinex pretty fucking iffy.
I stopped trading on bitfinex (except for some toy amounts) a while ago, so I'm only peripherally following this... can you tell me if there were any *actual* losses incurred to users after the rollback, or are the "losses" all in the form of "missed profits"? (makes some difference, IMO)
To be honest, I have no idea how this works. I know that it is clear that some traders -- including myself -- profited nicely, and had trades trigger well below the bottom on Bitstamp, and I don't know who incurred the losses (traders or Bitfinex). My guess is both. They did not roll back all transactions to the start of the bug, which means that trades that executed well outside of Bitstamp's range (up to $829 and down to $678) may have stuck. I imagine many stops were triggered.
The fact that Bitfinex appears to have rolled back transactions based on an arbitrary price range that they set (e.g. below $720 or below $700), tells me that people incurred real losses. Traders holding longs with stop losses below $750 lost. Traders holding shorts with stop losses above $790 lost.
