指標繪製不是預期的結果

Input: UpPct(7, "上漲百分比(%)"),DownPct(3, "下跌百分比(%)");

SetTotalBar(10); 

If BarFreq = "Min" And BarInterval > 60 Then Return; 

If (BarFreq = "D") Or (BarFreq = "W") Or (BarFreq = "M") Or

   (BarFreq = "Q") Or (BarFreq = "H") Or (BarFreq = "Y") Then 

Begin

    Return; 

End;

Vars: YesterdayClose(0);

YesterdayClose = closeD(1);  

If YesterdayClose = 0 Then Return;

Vars: TargetUp(0);

TargetUp = YesterdayClose * (1 + UpPct * 0.01);

Vars: TargetDown(0);

TargetDown = YesterdayClose * (1 - DownPct * 0.01);

Plot1(TargetUp, "上漲目標價"); 

Plot2(TargetDown, "下跌目標價");

這兩條線不論是用PlotLine還是Plot，都不是預期的結果，畫面縮放還會出現在別的地方，不是依照計算出的數值繪製

請教是哪個部分有錯?
另外是否能正確顯示在江波圖裡?
