Hello,
From time to time, all brokers screw up. I've been told that there are official channels through which individual traders can lodge complaints about brokers' malfeasance, but I'm not sure what those channels are. I am starting this thread in order to ask our Traders Lab community if they know what to do when a broker messes up. If you know for sure what to do, please reply here.

I decided to start this thread because Tradestation has been charging customers inappropriately for data services which the customers don't actually recieve, in direct contradiction to their own rules. This is not as seroius as complaints about trading violations, so I'm not sure if:
a) this is the sort of problem one should complain about, or,
b) to whom does one complain about such a violation?

In a sense, charging customers for data they don't receive is just as much a monetary issue as not filling a buy stop order, but I think that these two issues are percieved differently. So, my questions to anyone who knows would be:
1) to whom would one complain for direct trading errors (e.g. stop orders not being hit)?
2) would the appropriate authority be different for stocks vs. futures vs. options vs. Forex?
3) are complaints about data feed errors directed to the same authorities or should one complain to some other authority (and whom would that be?).

If there are other issues I've left out here, please address them here. Knowing where and when and to whom one should complain is a serious issue, and Traders Lab should (IMHO) have this information available for its members.

Good (and error-free) Trading to you all,
Taz
