執行顯示 " 策略的商品執行範圍不存在(50201)",怎麼辦?

程式很簡單,想找月線附近的股期,但發生錯誤,如何解決?

condition2= c>c[1] or H>H[1];

condition3= c>100;

condition4= c>average(c,20)*0.97 and c<average(c,20)*1.03;//股價站20日線3%附近

if  condition2 and condition3 and condition4 then ret=1;

outputField(1,(c/average(c,20)-1)*100,2,"離月均線%");

outputField(2,LinearRegAngle(average(c,20),3),2,"20日均線3天線性迴歸角度");

outputField(3,GetField("股本(億)", "D"),"股本(億)");

拜託您了...
