There are some flaws in your understanding and requirements. According to your original intention, I think the stock selection formula has great defects. If you choose stocks by it, it is inefficient and ineffective. Based on the above reasons, I have made some changes, and the overall idea has changed slightly, but it is more practical. I pressed the name myself. Parameter: p 1 {0, 100,90} The formula is as follows: a: = p1+(100-p1)/2; b:=( 100-p 1)/2； CC:= cost (a); DD:= cost (b); ↑ 1:IF((CC-DD)/(CC+DD)* 100/2 & gt； REF((CC-DD)/(CC+DD)* 100/2，BARSCOUNT(C)- 1)+ 10， 1，0)； If you want to see the SCR value in the stock selection column, you can use the following formula: a: = p1+(100-p1)/2; b:=( 100-p 1)/2； CC:= cost (a); DD:= cost (b); SCR 1:(CC-DD)/(CC+DD)* 100/2； SCR2:REF(SCR，bars count(C)- 1)+ 10； ↑ 1:IF(scr6 5438+0 & gt； SCR2， 1，0)； After stock selection, the speculative value of ↑ 1 stock will be greater, and vice versa! I hope I can help you!
