[語法請教] 函數歷史資料引用問題

tapehero

語法問題請教版上先進:
小弟寫了下面的程式想要算出pivot點當天5/10/30日均值:

當程式碼寫成下面時，算出來的pivotH3FastMA/pivotH3MidMA/pivotH3SlowMA都是不對的(算出來的值都是最後一根k的)  

Inputs: Price(Low),
        LeftStrength3(4), RightStrength3(2),

      FastLength(5), MidLength(10), SlowLength(30);

pivotH3V = PivotHighVS(1, High, LeftStrength3, RightStrength3, RightStrength3+1);
   pivotH3Bar = PivotHighVSBar(1, High, LeftStrength3, RightStrength3, RightStrength3+1);   
   if pivotH3Bar >= 1 then begin
      pivotH3FastMA = AverageFC(Close,  FastLength)[pivotH3Bar];
      pivotH3MidMA = AverageFC(Close, MidLength)[pivotH3Bar];
      pivotH3SlowMA = AverageFC(Close, SlowLength)[pivotH3Bar];

-------------------------------------------------------------------------------------------------------------------------------------------------------------------
但如果把其中的FastLength, MidLength, SlowLength改成數字就正確了，請問這是什麼問題呢?
另外想請問: 函數是否不能引用變數呢? 謝謝指教~

pivotH3V = PivotHighVS(1, High, LeftStrength3, RightStrength3, RightStrength3+1);
   pivotH3Bar = PivotHighVSBar(1, High, LeftStrength3, RightStrength3, RightStrength3+1);   
   if pivotH3Bar >= 1 then begin
      pivotH3FastMA = AverageFC(Close, 05)[pivotH3Bar];
      pivotH3MidMA = AverageFC(Close, 10)[pivotH3Bar];
      pivotH3SlowMA = AverageFC(Close, 30)[pivotH3Bar];

TRY THIS: Change "AverageFC" to "Average".
