Such as the moving average system.

The golden fork is long and the dead fork is short. Just open the warehouse.

As for the liquidation, stop loss or stop winning.

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.
