HTS AverageModifiedMethod 轉 TradeStation

基本上這個函式不算太難…反而比較需要注意的是 TradeStation 在命名上的字數限制…
所以這邊就把這個函式命名為 AvgModifiedMethod


原始的 HTS 程式碼：

Parameter: Price(Numeric), Length(Numeric)
Variables: Days(0), MV(0), Prev(0)

Days = Days[1] + 1
MV = 1 / Length

If Days < (Length + 2) Then
AverageModifiedMethod = Price
ElseIf Days = (Length + 2) Then
AverageModifiedMethod = MA( Price, Length)
Else
Prev = AverageModifiedMethod[1]
AverageModifiedMethod = Prev + MV * (Close - prev)
End If


轉換為 TradeStation 後的程式碼為：

Input: Price(Numeric), Length(Numeric);
Variables: Days(0), MV(0), Prev(0);

Days = Days[1] + 1;
MV = 1 / Length;

If Days < (Length + 2) Then begin
AvgModifiedMethod = Price;
End
Else If Days = (Length + 2) Then begin
AvgModifiedMethod = Average( Price, Length);
End
Else begin
Prev = AvgModifiedMethod[1];
AvgModifiedMethod = Prev + MV * (Close - prev);
End;


多注意一下 If ... else 的用法和命名即可。
