yes they do. pretty much everything more than 3% away is in question. and you never know when trade can be reversed. i know few people,who been burned very badly over those erroneous trades
very few of reviewed trades are adjusted... i would say less than 10%. i have worked on these desks so this is only from my opinion at one desk, still only imo
got a question.....the ruling is that on that google fiasko they were going to break all trades at or below $352.07......why dont all those shares that traded at $38 bucks just get the price of #352.08? wouldnt that be fairer than cancelling the trades all together?.....the dumbass who sent the order should have to suffer some consequence....no????
i think it's depends on how big the dumbass on other side, if he big enough-he will walk away with zero damage 99.9% of time
At least think about this conspiracy possibility: Some big guys definitely knew the market would go higher and also knew that a trade at 10% of original value will be broken.. At least it's nice to get some people stopped out, stops triggered
