随手风

DIFF:=EMA(CLOSE,5)-EMA(CLOSE,26);
DEA:=EMA(DIFF,50);
MACD:=2*(DIFF-DEA);  
AA:=COUNT(CROSS(DIFF,DEA),BARSLAST(DEA>=0));
低位二次金叉:=CROSS(DIFF,DEA) AND DEA<0 AND COUNT(AA=2,21)=1 AND MACD<0;
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);
低位二次金叉 OR 底背离;
