Quote from OldTrader:
Just a few comments:
1) Before you knew what had happened or whether there was a problem at all, you were posting here on the board hammering IB. Not the way a professional handles matters in my opinion. The first step is to contact IB, find out if you are filled. If there is a problem with the fill, you then discuss that with IB to find some type of resolution. Hammering the broker before you even know if there is a problem, or for that matter, before you have discussed it with them is a sign of immaturity.
2) What you received is a standard form letter. This letter by itself would not be acceptable to me. I would want to know more about what happened and why it happened, so that I could take some sort of steps to remedy the situation. But if this is really true, that it is a problem with "market data", then the implication is that the stop was held on the IB server, not on an exchange. And therefore you opened yourself up to an error when IB had a problem that happened to coincide with the triggering of your stop.
I would want my stop to be held on an exchange, not on IB's server...and therefore that's one element of what I would want to determine here. Frankly, if your stop was held by IB, and you had a means of having it held by the NYSE for example, you in the end have to take the responsibility for not knowing how to best enter your order to protect yourself.
Now, if your stop was actually held by an exchange, and IB claims the problem was "market data", that is bullshit. But I doubt that is the case. I might add that I am a supporter of IB, I trade with them, I think they are a great company. But when I start to see or hear the above letter more than a few times, I start to think IB is not remedying the problem, and that is it high time to remedy the problem.
