Closing position without in warning even if you have margin.

Had a horrible experience with this broker!!! Beware as I've lost over 8k without any margin call or warning what so ever, all my positions were closed yet I had over 300% margin left... I couldn't even fund my account again cause they closed it with all the margin I said had left, 200usd, I'm disappointed in this broker and will not recommend them at all, do not use them I warn you now...
