請問小編，我寫了一個語法，要得到今日的日K、周K及月K上布林的UB2.00大於昨日的UB2.00，今日的下布林LB2.00小於昨日的LB2.00，目前跑出來只有日K及周K正確，月K的部分不對，想請小編幫我看一下哪裡出錯，謝謝

Value1=close;

Value2=getfield("Close", "W");

Value3=getfield("Close", "M");

Value4=BollingerBand(Close,20,2);

Value5=BollingerBand(Close,20,-2);

Value6=BollingerBand(Value2,20,2);

Value7=BollingerBand(Value2,20,-2);

Value8=BollingerBand(Value3,20,2);

Value9=BollingerBand(Value3,20,-2);

Value10=AVerage(close,20);

Value11=AVerage(Value2,20);

Value12=AVerage(Value3,20);

IF Value1 > Value1[1] and Value1 > Value1[2] and Value1 > Value10

and Value4 > Value4[1] and Value5 < Value5[1]

and Value2 > Value2[1] and Value2 > Value2[2] and Value2 > Value11

and Value6 > Value6[1] and Value7 < Value7[1]

and Value3 > Value3[1] and Value3 > Value3[2] and Value3 > Value12

and Value8 > Value8[1] and Value9 < Value9[1]

and Volume > 1000

then ret=1;

(1)你需要先釐清，是

月K上布林的UB2.00大於「昨日」的月K上布林的UB2.00，

還是

月K上布林的UB2.00大於「前一根」月K上布林的UB2.00

(2)跨頻率處理，應盡可能避免用變數處理，以免造成邏輯錯誤。
