副图指标（macd）选股预警公式

编写要求：

请老师帮忙改一个副图指标（macd）在出红箭头的位置写一个选股预警公式。上张图共老师参考。DIFF :=( EMA(CLOSE,9) - EMA(CLOSE,26))*100;DEA :=EMA(DIFF,12);MACD :=2*(DIFF-DEA);绿柱消失买入:STICKLINE(DIFF<0,0,DIFF,2,0),COLOR00FF00;红柱消失卖出:STICKLINE(DIFF>=0,0,DIFF,2,0),COLORRED;STICKLINE(DEA>=0,0,DEA,2,0),COLORBLUE;STICKLINE(DEA<0,0,DEA,2,0),COLORYELLOW;DRAWICON(CROSS(DIFF,DEA),DEA*1.1,1);DRAWICON(CROSS(DEA,DIFF),DEA*1.1,2);强1:IF(DIFF>DEA,DIFF,DRAWNULL),COLORRED,LINETHICK2;强2:IF(DEA0,抄底,' 抄底'),COLORRED;DRAWICON(ABS(抄底)>0,抄底,9);

解答：

 diff:=( ema(close,9) - ema(close,26))*100;
