将出现红箭头为预警公式

编写要求：

DIFIF1:=EMA(CLOSE,12) - EMA(CLOSE,26); DEAEA1:=EMA(DIFIF1,9); MACD1:=2*(DIFIF1-DEAEA1),STICK; MACD2:=EMA(MACD1,3); STICKLINE(MACD1>MACD2 AND MACD1>0,0,MACD1,1,0),COLORRED; STICKLINE(MACD1>MACD2 AND MACD1<0,0,MACD1,1,0),COLORGREEN; STICKLINE(MACD1=0 OR MACD1<=0,0,0,50,1),COLORWHITE; DIFIF1,COLOR33FF33; DEAEA1,COLORYELLOW; MACD:MACD1,NODRAW,COLORMAGENTA; 强:IF(DIFIF1>=DEAEA1,DIFIF1,DRAWNULL),COLORRED,LINETHICK2; 弱:IF(DEAEA1>=DIFIF1,DEAEA1,DRAWNULL),COLORFF9900,LINETHICK2; DRAWICON(CROSS(DIFIF1,DEAEA1),DEAEA1-0.02,1);

解答：

?DIFIF1:=EMA(CLOSE,12) - EMA(CLOSE,26);

DEAEA1:=EMA(DIFIF1,9);
