我把marketposition = Cum(Buy+Cover-Short-Sell);放進去接著我的買賣條件
buy=marketposition = 0 AND "aaa" and barcomplete;
檢查錯誤為...
Error 29.Variable "buy" used without having been initialized
Error 29.Variable "sell" used without having been initialized
Error 29.Variable "short" used without having been initialized
Error 29.Variable "cover" used without having been initialized
