主题：关于MACD的判断公式如何编写

我在网上找了一段用于大智慧中的底背离判断代码，请各位老师看一下是否能借鉴：

{以下处理底背离}
N1:=last(MACD<0);{绿柱天数}
N2:=REF(last(MACD>0),N1);{绿柱前红柱天数}
N3:=REF(last(MACD<0),N2+N1);{红柱前绿柱天数}
MINMD1:=LLV(MACD,N1);
MINMD3:=REF(LLV(MACD,N3+N2),N1);
MINDIFF1:=LLV(DIFF,N1);
MINDIFF3:=REF(LLV(DIFF,N2+N3),N1);
MINDEA1:=LLV(DEA,N1);
MINDEA3:=REF(LLV(DEA,N2+N3),N1);
股价L1:=LLV(L,N1);
股价LL:=LLV(L,N1+N2+N3);
绿柱缩短:=MACD<0 AND MACD>REF(MACD,1) AND REF(MACD,1)<REF(MACD,2);
MACD底背离:=MACD<0 AND MINMD1>MINMD3;
DIFF底背离:=DIFF<0 AND MINDIFF1>MINDIFF3;
DEA底背离:=DEA<0 AND MINDEA1>MINDEA3;
股价新低:=股价L1=股价LL;
底背离:绿柱缩短 AND? MACD底背离 AND DIFF底背离 AND DEA底背离 AND 股价新低,COLORRED,PRECIS0,LINETHICK0;
