Analysis is just 30 percent and your psychology as a trader is 70 percent, and psychology is the what prevents you from loses, no doubt you will lose but not frequently, since Thursday last week I only closed one trade in lost now, is not because I didn't do my analysis well, but because I allow my emotions to control me, and I close price still came back to that level and even passed it, so trading psychology is what will keep you profitable, Even when you lose don't revenge look for another correlated pair and trade, sometimes too our risk management is the problem, but to put it all if your trading psychology is not balance there won't be risk management and poor psychology comes with guess work and mistakes
