STOP THERE NOW !  Loss of 40% is already a big percentage of loss. you should never make a loss of 40% at a single trade .first of all Practice your trading skills atleast for 3 to 4 months on Demo account and if there you getting good profits then you go for Trading live account with minimum amount you can afford to loose at any circumstances. In trading you should keep one thing in your mind,  YOU DONT WANT TO BE TRUE, BUT YOU NEED TO BE SURE ALL THE TIME , i follow these lines on every single trade i take.
