週頻率選股策略 repeat 語法用不出來

小編你好

我嘗試在週頻率上計算MACD oscValue 有幾根綠棒

在日頻率使用相同語法可行, 但換到週頻率就跑不出結果

input: FastLength(12), SlowLength(26), MACDLength(9);

variable: difValue(0), macdValue(0), oscValue(0),i(0),

          _1st_G_1stBar(0),_1st_G_lastBar(0);

setbarfreq("W");

SetTotalBar((maxlist(FastLength,SlowLength,6) + MACDLength) * 4);

MACD(weightedclose, FastLength, SlowLength, MACDLength, difValue, macdValue, oscValue);

condition1 = Close > PriceLimit;

condition2 = difValue >0;

condition3 = macdValue >0;

condition4 = oscValue >0;

If condition1 and condition2 and condition3 and condition4 then 

begin

i=0;

Repeat

  Begin

    if oscValue[i]>=0 then

    i = i + 1;

  End;

Until oscValue[i]<0;

_1st_G_1stBar =i; //第一根綠棒

Repeat

  Begin

    if oscValue[i]<=0 then

    i = i + 1;

  End;

Until oscValue[i]>0;

_1st_G_lastBar= i-1 ;//最後一根綠棒
