In some positions, both long and short positions can be traded, that is, the profit and loss ratio is 1:1. Orders that can be traded in both long and short positions are not suitable for trading.

Some systems are based on winning rate, and this can consider a lower profit and loss ratio, but my system is not, it only does profit and loss ratio + a small stop loss that needs to be strictly enforced.

You may not lose money once if you make 10 mistakes. The problem is that many people have a fluke mentality when doing stop loss, and I can't overcome it either. I always wonder if it is a false breakthrough.
