Quote from fullblotter:
on arca the guideline is $1 out of market or 10%. if no one complains and it's even outside the guideline they will usually let it stand, as long as it's within reason. if the other party complains arca issues a ruling. they will usually let the trade stand if it's within the guidelines but sometimes they will break it. ultimately it is their discretion. there is also the possibility of a trade adjustment if both parties agree.
on nasdaq it is 20% away for a trade break.

I've been involved with many busted/adjusted trades. I've gotten explanations from NASDAQ that are completely inconsistent and the opposite of the reasoning given for other break decisions. They have a bunch of guidelines. But, it usually just comes down to "we do what we want."

Is that anyway we can complain about it? I don't even got any exapanations. A few thousands profit was gone.
Quote from fullblotter:
there is usually a small time frame within which you can appeal the decision. for arca it costs $500. you have to get your firm to make the appeal. when you have a trade that is borderline a lot of it comes down to your firm. if they fight for you they can prevent a break or at least get it adjusted. if they don't arca usually just breaks it.
I find nasdaq a lot more inconsistent than arca. nasdaq says 20% but they do what they want basically.
