Such as the moving average system.
The golden fork is long and the dead fork is short. Just open the warehouse.

Lose 8 points, stop loss is even, and win 15 points, that's right.
However, everyone's trading system is different, and I can't tell you too many system rules, so as not to bind my own views.
The system must have an advantage in statistics, at least in fund management.
