可以參照HighD寫個類似的HighW，呵呵- Params
- Numeric WeeksAgo(1);
- Vars
- NumericSeries barCnt;
- NumericSeries WeekHigh;
- Numeric i;
- Numeric j;
- Numeric nIndex(0);
- Numeric CBIndex;
- Begin
- CBIndex = CurrentBar;
- If(CBIndex == 0 || IntPart(DateDiff(19700105,Date)/7) != IntPart(DateDiff(19700105,Date[1])/7))
- {
- barCnt = 1;
- WeekHigh = High;
- }Else
- {
- barCnt = barCnt + 1;
- If(High > WeekHigh)
- WeekHigh = High;
- }
-
- If(WeeksAgo == 0)
- {
- return WeekHigh;
- }Else
- {
- For i = 1 To WeeksAgo
- {
- If( i == 1)
- {
- j = 0;
- }Else
- {
- j = j + BarCnt[j];
- }
- If (j > CBIndex )
- Return InvalidNumeric;
- nIndex = nIndex + BarCnt[j];
- }
- Return WeekHigh[nIndex];
- }
- End
- Params

呵呵，好像不行啊，程序不認(rèn)這個HighW～

我的意思是，你自己新建一個用戶函數(shù)HighW，我照葫蘆畫瓢寫了一個，你試試吧 - 網(wǎng)友回復(fù)：

參考一下這個：- Params
- Numeric weeksAgo(2);
- Vars
- NumericSeries barCnt;
- NumericSeries weekHigh;
- Numeric i;
- Numeric j;
- Numeric nIndex(0);
- Begin
- If (Day-Day[1]>1 Or Day-Day[1]<0)
- {
- barCnt = 1;
- weekHigh = High;
- }Else
- {
- barCnt = barCnt[1] + 1;
- If(High > weekHigh)
- weekHigh = High;
- }
- If (weeksAgo == 0)
- {
- Return weekHigh;
- }Else
- {
- For i = 1 To weeksAgo
- {
- If (i == 1)
- {
- j = 0;
- }Else
- {
- j = j + barCnt[j];
- }
- If (j > CurrentBar)
- Return InvalidNumeric;
- nIndex = nIndex + barCnt[j];
- }
- Return weekHigh[nIndex];
- }
- End
- Params
