According to my trading experience, I can say leverage is considered as an important financial tool that allows an investor to grow his market exposure to a level that exceeds the initial investment. From my first day of trading I like t trade in a high leverage. So, I took high leverage in my demo account in my trading place TradingBanks to see the performance how it works. After taking high leverage, I did huge loss. So, now I trade with a small leverage even though I am getting 1:400 leverage from my trading platform. so, my trading life is secure.
