Disliked{quote} What I can to say is there are a lot of question I want to know. I did the trade based on my strategy. It is a normal day for me. it is consistent with my past records even same as the last account. They didn't have any evidence based on the talk with the director. He said my trading size increase dramatically from 30k to total (not single) 200lots (this is definitely my strategy, and last 6 months my overall trading volume is about 2700lots). they suspect I know the market information and they use raw data to adjust that. Their adjustment...Ignored
Only you know if what you did was in violation of your contract with them.
If this is the second time they've closed your account for a contract violation, that doesn't look good. It doesn't make sense to open another account if you had a problem with them the first time and it's difficult to get money back once it's gone with a broker. It took years of litigation when people were fighting Gain Capital a few years back. That doesn't mean you should give up if you really want to fight it, but it's going to take time and energy and you probably won't recover the money. You got your principle out and 49K profit which is substantial. People lost everything with MF Global, and a few other brokers, and will never recover their loses.
You need to be a lot more careful.
With the type of trading you seem to want to do, a low spread Forex bucket shop isn't going to work. They put those rules there for that reason, and the STP ECN Forex model with commission and spread makes those type of quick turnarounds more difficult. Depending on your total capital, you might want to look into Level III access and bypass the spread completely. Then you can trade very tight turnarounds without the same entry barrier.
