我认为很好用的MACD指标公式，副图

DIFF:EMA(CLOSE,12) - EMA(CLOSE,26);
 DEA:EMA(DIFF,9);
 MACD:2*(DIFF-DEA),COLORSTICK;
 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
