if the price went above his limit price then the execution should not have occurred .... period. he should find the log files and file a complaint, no matter how many days have passed.
Great point.....why else would someone try and place a limit $10 below the closing price if not to take advantage of another trader hitting your (OP's) bid, ceteris paribus.
As someone already mentioned (in less detail), you do have 20 minutes to break a trade if it is a clear mistake and grossly outside the range of previous trades in the stock. This is an exchange policy, not an IB policy. It's too late now, but you definitely need to be aware since it's going to happen again if you use TWS long enough and are going to mess around when stocks are illiquid. http://www.nyse.com/pdfs/NYSEAmexObviousErrorRule.pdf http://www.nasdaqtrader.com/trader.aspx?id=clearlyerroneous
No offense,you screwed yourself shorting 400 share at 76 and watching it go 10 points against you.You did have an unrealized loss on the books.If you are so he'll bent on staying short,just put yourvposition back on and dont worry about the fifty cents you paid up in AH.
He's a hypocrite for crying foul when getting picked off when that's exactly what he was attempting to do. He got screwed on 50 cents, but was fine to screw someone out of 10 handles on a fat finger. I have no problem picking someone off, but don't flap your labia looking for sympathy when you lose while attempting to do so. It was obviously a mkt order or he typed an 8.
by the way, you didn't mention the stock, its probably NFLX, will be funny if it goes straight down from here all the way to 0
It was most likely your mistake and I can almost guarantee if you check the logs again you will see that you entered a buy STOP limit instead of a buy Limit. You chose the wrong order type. A buy stop limit would protect you if your short position exceeded a certain price and then would become a market order. In this case you entered a buy stop limit order at 76 but since the stock was already trading above that price it was automatically triggered and became a market order and filled at the price that was currently available. So you would have seen 76 on the screen when entering order but you didn't check the order type enough times to see the error.
