Hi All,
I'm using ICM since last Feb, they are a very good company in a lot of aspects, very accurate and speedy when it comes to fund/withdrawal process, however they send me an email with detailed statement after each and every trading day, this is a very strong evident that everything is fine and in it's place, else you should respond to the wrong statement and contact them to know what is happening (didn't happen to any one i know yet).
However, go back to these days statements and compare them and see what happened exactly.
I made tons of withdrawals from them and never seen something with (-) before! Maybe a technical error or something I don't know, but my experience says that their customer service is amazing and very helpful and very responsive.
All the best
I hope you don't wake up one day to see your positive balance turned to a huge negative because icmarkets don't like the way you trade.
