Leverage in Forex trading is a tool that enables us to open big size trade with small capital. It is the leverage that helps us to to make more profit with a small capital. But it is difficult to pick the best leverage level one should use, as it in a general sense relies on the individual trader's trading procedure. But if you want to hold your trade for longer term, use less leverage. For my trading I utilize 300:1 leverage however my broker XeroMarkets provides for 500:1.
