In forex, traders use leverage to profit from the fluctuations in exchange rates between two different countries. Leverage is a credit that is provided to a trader by the broker that is handling his or her forex account. Usually, the amount of leverage provided is either 50:1, 100:1 or 200:1, depending on the broker and the size of the position the trader is trading. Standard trading is done on 100,000 units of currency, so for a trade of this size, the leverage provided is usually 50:1 or 100:1. Leverage of 200:1 is usually used for positions of $50,000 or less. I am also not having big capital but I am using 200:1 as my leverage instead of using more leverage than that. I think best leverage is for a trader is 200:1
