Leverage falls into a good offer from the broker. If I trade with good deposits, I need to use 1:50 leverage. This will protect my account. Leverage will prevent me from overtrading. But if I trade with a small deposit. But I have to select more leverage. Because if I select low leverage with a small deposit, it will be very difficult for me to trade.
In Fx trading , leverage is useful for trader , especially if trader start with small balance hence with leverage it will giving opportunity to making transaction on Fx market , now some broker offer high leverage until 1:1000 but so far I am only use leverage 1:400 as maximum.
