The concept of stop loss: the benevolent sees benevolence and the wise sees wisdom, look for a wave of market conditions, use positions for risk control, stop loss is in the mind, not necessarily in the disk; for some players who like to trade heavily, the stop loss has to be brought on the market It is a last resort. I think this approach is desirable, but I don’t like it, because I don’t trade heavy positions, and I don’t like heavy positions. Long-term steady profits are my ultimate goal. As a trader for 13 years, if I took heavy positions, I would have already exited the market. The authors of many signals in the market are very good traders, but the reason why many signals are liquidated during operation is 100% due to heavy positions.
