In all fairness, they should bust both sides of the trade. I.e. anyone who bought long and had the trade busted should have the corresponding sell busted as well. Assuming OP scenario is true, there is a very valid complaint here.
Maybe I'm missing something, but I don't see why it would be so difficult to match up any round trip positions during the bust action (FIFO) and invalidate them.
Quote from Ghost of Cutten:
There is a solution, it is to not bust trades, but rather to re-price them to the low of the day that is considered "normal" and not a mistrade, erroneous trade, or massively out of whack. That way people do not get penalized for providing liquidity, people get punished - but not excessively - for placing erroneous trades or stupid market orders with no limit during crashes or volatile conditions, and noobs don't end up with debit balances because of capricious decision-making at exchanges.
The existence of unilateral trade busts means that in a true market crash, less liquidity is provided. Liquidity providers will shy away from providing bids & offers because if they get filled and it turns out to be a loser, the trade won't get busted; and if they get filled and it's a winner, the trade will get busted. Heads you lose tails they win. Also, if you get filled at a low price during a crash, you then have that margin tied up because you don't know if you will keep the position or not - you cannot use that money to buy other stuff, and you cannot exit the trade for fear of it being busted and ending up naked short. Trade busts paralyze market liquidity during crashes, when it is most needed.
Efficiency's position is silly and illogical - down 59.9% was not ridiculous but down 60.1% was?
Trade busts, rather than re-pricing, are morally indefensible, damaging to market liquidity and efficiency, and have no upsides whatsoever. They should be outlawed.
Damn right. If I f*ck up and hit "sell" instead of "buy", or 10000 instead of 100, or what ever else I do to screw up, I'll take the hit. I fess up to my mistakes.Quote from Ghost of Cutten:
