2026-01-28 XQ部落格 P&L Chart 指標的藍色"臨界值直線"是如何畫出？試著寫成選股腳本，請問有無錯誤或改善之處？

var: Flag_PLChart1(false);   // 股價長期低於P&L Chart，近日站上

Flag_PLChart1 = (countIf(C[10]<=LastPoint[10],40)>=32 and countIf(C>=LastPoint,10)>=8 and C>=LastPoint) or 

                (countIf(C[10]<=LastPoint[10],80)>=64 and countIf(C>=LastPoint,10)>=8 and C>=LastPoint) or

                (countIf(C[10]<=LastPoint[10],120)>=96 and countIf(C>=LastPoint,10)>=8 and C>=LastPoint) or

                (countIf(C[15]<=LastPoint[15],40)>=32 and countIf(C>=LastPoint,15)>=12 and C>=LastPoint) or 

                (countIf(C[15]<=LastPoint[15],80)>=64 and countIf(C>=LastPoint,15)>=12 and C>=LastPoint) or

                (countIf(C[15]<=LastPoint[15],120)>=96 and countIf(C>=LastPoint,15)>=12 and C>=LastPoint) or 

                (countIf(C[20]<=LastPoint[20],40)>=32 and countIf(C>=LastPoint,20)>=16 and C>=LastPoint) or 

                (countIf(C[20]<=LastPoint[20],80)>=64 and countIf(C>=LastPoint,20)>=16 and C>=LastPoint) or

                (countIf(C[20]<=LastPoint[20],120)>=96 and countIf(C>=LastPoint,20)>=16 and C>=LastPoint);

if Flag_PLChart1 or 

   Flag_PLChart1[1]

then counts=counts+1;
