金叉箭头的预警公式

编写要求：

DIFF:EMA(DCLOSE,12)-EMA(DCLOSE,26);DEA:EMA(DIFF,9),COLORFFFF00;MACD:(DIFF-DEA)*2;STICKLINE(MACD>=0 AND MACD>=REF(MACD,1),0,MACD,1,0),COLORRED;STICKLINE(MACD>=0 AND MACD<=REF(MACD,1),0,MACD,1,0),COLORGREEN;STICKLINE(MACD<=0 AND MACD>=REF(MACD,1),0,MACD,1,0),COLORFF00FF;STICKLINE(MACD<=0 AND MACD<=REF(MACD,1),0,MACD,1,0),COLOR00FFFF;DRAWICON(CROSS(DIFF,DEA),DEA,1);DRAWICON(CROSS(DEA,DIFF),DEA,2);

解答：

DIFF:=EMA(DCLOSE,12)-EMA(DCLOSE,26);
