I have accidentally short-sell stocks on IB platform and the order went through. This is what I particularly hate about IB platform despite being happy on most counts. I wish they will stop customers' orders which are accidental short-sell. Most customers have no intention to short-sell.

doh, I just noticed my system is long IBKR while this news came out !
And yes, the system runs on IBKR. Irony![]()
Who owns the rest of the brokerage?
