Many a times , Forex traders do trust their brokers and give them the discretionary powers. This can be extremely risky or harmful for them as the brokers sometimes take undue advantage of their powers and churning is one of them. With excessive trading they can put the trader's money at big risk and immerse them in various taxes in the time of excessive profit. For this reason, the trader must maintain complete control over their account. He must also keep asking questions from time to time to let the broker know that the trader is alert always!
