Quote from ddaytrader:
This isn't option related but it is Interactive Brokers related: on August 1st I had a sell stop (a stop market, not a stop limit)to go short the EURUSD at Interactive Brokers. Price traded at and below that level for about twenty minutes before the market broke lower. For twenty minutes, the market was offered at my stop level or lower. IB's own Time & Sales data confrims that many transactions took place at and below my stop level during that time.
However, Interactive Brokers did not fill my order for nearly 30 minutes, and when they did fill it, it was after the market broke lower. I was filled at a price more than 50 pips lower than my stop order. This was a stop market order. IB's customer service acknowledges that the order should have been filled about 55 pips higher than it was. However, my request for compensation has, nearly a month later, gone unanswered. When I inquire, I am simply told that "senior management is aware of the issue."
So, if you have qualms about trading at IB, perhaps you should listen to your gut. I will say that while this is not first time I had a problem with an FX trade at IB, it is the largest error in their favor, and it is the first time that they have not done the right thing in a timely manner.
In fact, it would seem that after a month, Interactive Brokers has no intention of doing the right thing, and is simply hoping that it goes away without me or anyone else affected filing a comp-laint with the CFTC's reparations program.
I am still trading with Interactive Brokers, but my trust level is destroyed, and I am very nervous about whether my stop orders, especially stop loss orders, will be honored.
I am never margined heavily, but if I were to trade a strategy that used high margin I would be very hesitant to employ that strategy at Interactive Brokers, because should an autoliquidation take place at a price unjustifiably unfavorable to you, you might find it very difficult to get Interactive Brokers to act rightly.
I am hoping Interactive Brokers does the right thing, but after more than 30 days, I would have to say that Interactive Brokers has been, in this particular case, untrustworthy.
