DIFF:EMA(DCLOSE,12)-EMA(CLOSE,26);
DEA:EMA(DIFF,9);
MACD:(DIFF-DEA)*2;
低位金:CROSS(DIFF,DEA) AND DIFF<-0.1;
JCCOUNT:=COUNT(CROSS(DIFF,DEA),BARSLAST(DEA>=0));
二次金:CROSS(DIFF,DEA) AND DEA<0 AND COUNT(JCCOUNT=2,34)=1;
A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
底背离:REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA);
A2:=BARSLAST(REF(CROSS(DEA,DIFF),1));
顶背离:REF(CLOSE,A2+1)<CLOSE AND REF(DIFF,A2+1)>DIFF AND CROSS(DEA,DIFF),COLORRED;
强:IF(DIFF>=DEA,DIFF,DRAWNULL),COLORRED,LINETHICK2;
