I m with forex for 1 and half year. I loss my capital several time for not using stop loss and for many reason that one bad trader have. Now i m profiting well. I believe that "Failure is the Piller of Success...." its totally happen to me and my trading.
So don't hopeless. Try more and more and doing more demo trade. sharp ur skill with it. One day the time will come when u r rock with forex.
wish all the best to all.
