ECN brokers... Ever reverse trades?

I have been trading with Hotspotfx for nearly two months now, and I am happy with the change, but I have a question for those who have been trading at Hotspot or any other ECN for a longer peroid of time. I see that the trades I close don't get added to my balance until after three business days. My question is, has anyone ever had a trade that didn't get added after 3 days? Like was there ever a time that you had a trade filled on an ECN and them reverse it later, saying it was an error or something? I know that this happened to me a couple times at Oanda and often told that a spike was a false quote over at MIG. But I haven't notice any problem like that at Hotspot yet. If anyone has ever had a trade reversed with an ECN please let me know. Thanks.

They will "bust" a trade if there was a technical malfunction. That's why you have to sign the electronic trading agreement. I've never heard of them reversing one otherwise.

weird, this isn't a T3 system like trading stocks. You know hotspot is owned by Knight Capital, one of the largest MM in the stock world.

Have you had a trade busted before? If so, did they explain what the technical malfunction was? Thanks in advance.

Not personally. My broker at the time sent an email to everyone that certain trades had been busted by the exchange due to a malfunction in the price feed. I think the instrument was mini-SP on CME Globex.

Thanks for the feedback Ken. And it's nice to know that it hasn't happened to you either. I am more and more pleased with my decision to go with an ECN.
