IB/TWS trader for 10 years. I pull a Fat-Finger about once a quarter. *Somehow* -- for about...... 6-9 months, now? No Fat-Finger. I'm waiting. I've even had a couple of "Almost(s)!" *Usually*, I can get out of them for flat, cash-wise. Mental/attention costs are in the $millions. (IMHO.) $200? I'd count myself lucky: you're out. You don't have to look at that wart for the next 6 weeks or whatever..... By the way: a sticky mouse button will reveal itself in just this sort of way, if you have your TWS set-up for 1-button trades. Despite a non-smoking environment, an always-clean desk top, and so-called "gaming mouse" with switch pods good to "millions" of keystrokes, I go through a new mouse *at*least* every 6 months. Currently into my 3rd Logitech G-302 -- strong laser/software engine, ambidextrous, minimal "fancy" keys to get in the way. But I got this one around Thanksgiving/Christmas, and the primary key is going -- it clicks twice when I depress it once. It's starting to interfere with my ability to fly through some trades as quickly as I might need. But !!! I already have a spare on-hand. Best wishes.
don't feel bad.. it happens more than you think.. with IBKR, all future calendars are reverse celendars if you want to trade them "the normal" way (specially if you are used to CQG for charting given IBKR data is not all that great for spreads) ... its easy to forget about it tbh, and one ends up entering the trade in the wrong direction... worst part is when one only notices a few days later when the spread is moving in favor for the trade but the position is losing $$$ .... then I check closely and I see the mistake. I now verify things 3-4 times before I ever enter, specially if entering fly's since IBKR doesn't handle those as a single trade but rather one has to leg in manually... tbh, I dont understand why their spreadtrader cant handle it correctly... they would be so much better off if they allowed for retail to use TT or CQG as front end's...
I don't use IB but I've done lots of things like this before. Tough too if it's an early morning trade and you're rushed into it and haven't fully woken up. I feel for you, I hate when mistakes happen like this. Tomorrow will be a better day.
I'm surprised to hear that you were able to modify an existing order from being a buy order into a sell order. I was aware that IB allows you to modify the limit price, or modify the quantity. But I was not aware that you are allowed to change from buy into sell on an existing order.
Oh...got a new one to add to the mix. A "closing bell" trade in the wrong timezone. Just placed one. Shouldn't be a problem though, a fairly straight forward volatility play. Panicked when I saw 1:53 and ran to my app to enter. Really can complain though, vacation was paid for on vacation.
last time i looked there was another nasty bug. if you pause an order, then change the routing, it shows your change but does not respect it. uses the old routing. should be easy to fix, they just dont . very ugly . been like that for years?
I do this from time to time and as a matter of fact, I did it today. I bought long and decided to scale-in 50% more shares and it turned out I sold 50% of my shares instead. Didn't realize it until 30 secs later. I trade a mix of long and short which doesn't help. Also, I find myself mousing over the wrong button/key in anticipation of hitting it and catch myself at the last second. My hot buttons are even color-coded but regardless, I need 100% undivided attention when I hit the trigger and most times I don't. Something I need to work-on. Also another thing I've done was accidentally double-click the hot button for a double order. It happens as a new I'm a new trader.
