Tell my copy-trading friends about my general approach: I tend to aggressively increase positions when the market moves, and there will be many rolling position operations. But every roll will push the protective line. Don’t just see the position size getting large and cut losses to run (this can easily cause capital erosion and losses). If you see profits reaching your respective psychological expectations, you can manually close the position to take profits. Again, I remind everyone to regularly take profits, and try to use pure profits to copy trades. This way, there is no pressure and no risk!
