三个MACD底背离选股公式

发现三个MACD底背离选股公式，选择出的票子不统一，发给大家看看，讨论一下哪个才是最好的版本。

选股一：（注意包含了DCLOSE函数，是个移动函数，但是和普通的未来函数有区别，陆老师用的三合一选股用的就是这款）DIFF:=EMA(DCLOSE,12)-EMA(DCLOSE,26);DEA:=EMA(DIFF,9),COLORFFFF00;MACD:=(DIFF-DEA)*2;A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));A2:=BARSLAST(REF(CROSS(DEA,DIFF),1));底背离:REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA);

选股二：（其实就是把第一个选股公式的DCLOSE改为了CLOSE）DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);DEA:=EMA(DIFF,9);MACD:=2*(DIFF-DEA);A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)<DIFF AND CROSS(DIFF,DEA);

FILTER(B1>0,5)

选股三：DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);DEA:=EMA(DIFF,9);AB:=REF(DEA,20);BB:=REF(CLOSE,30);低值:=LLV(DEA,25);选股:CROSS("KDJ.J","KDJ.D")AND "KDJ.D"<30 AND DEA>AB AND DEA>低值 AND CLOSE<BB AND 低值<-0.2;
