My english is very poor. I think, make money from trading,not by small losing with big win, but by big win with small losing. I think, if we look at the small losing, will be difficult to catch the big win. We may be should lock the big win at first,and then we try everything we can do to let losing smaller and smaller. What I often do, is not run before market, but run after market. Up Buy Down Sell. If the market run on our trades direction, I will hold the trades,so the profit range will be unlimited. If we on the wrong term, market reverse, it doesn't matter, we have the stop-loss, losing range will be limited. My friend FunQi said to me, for a trading system,stick to and improve both are important.So, the general direction can not be wrong and be changed. I think, the trading system which conform to " Profit range unlimited and losing range limited ", may be the general direction. End.Thank you for reading.
