Cross Above Error

小幫手您好,

今日指標腳本在 1分K 處理 3693.TW 時，發生指標無法運算完成的狀況，經過小小測試後，測試腳本如下，發現 Cross Above在 2022/12/16 09:05:00 時無法正確執行完成：

SetBackBar (0);

var: dayOpenBar (0);
if isSessionFirstBar then
 begin
  dayOpenBar = CurrentBar;
 end;

var: BBAND_LENGTH (20), BBAND_BAND (2);
var: BBandLength (BBAND_LENGTH), BBandSD (0);
var: BBandMA (0), BBandUpper (0), BBandLower (0);

BBandLength = IFF (CurrentBar - dayOpenBar < BBAND_LENGTH, CurrentBar - dayOpenBar + 1, BBAND_LENGTH);
BBandMA = Average (Close, BBandLength);
BBandSD =  StandardDev (Close, BBandLength, 1);
BBandUpper = BBandMA + BBAND_BAND * BBandSD;
BBandLower = BBandMA - BBAND_BAND * BBandSD;

 PRINT (File ("[Date][StartTime]_[Symbol]_[StrategyName].log")
 , NumToStr (CurrentBar, 0)
 , DateToString (Date)
 , TimeToString (Time)
 , NumToStr (Open, 2)
 , NumToStr (High, 2)
 , NumToStr (Low, 2)
 , NumToStr (Close, 2)
 , NumToStr (Volume, 0)
 , NumToStr (BBandUpper, 3)
 );

 PRINT (File ("[Date][StartTime]_[Symbol]_[StrategyName].log")
 , NumToStr (CurrentBar, 0)
 , DateToString (Date)
 , TimeToString (Time)
 , "Close Cross Above BBandUpper"
 , Close Cross Above BBandUpper
 );

相關的 PRINT 輸出如下，在 09:05:00 發生錯誤後，下一根K棒的CurrentBar已經重頭變成1了
