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);

DEA:=EMA(DIFF,9);
