编写要求：

DIFF:=EMA(CLOSE,34)-EMA(CLOSE,55),COLORFFDDFF,LINETHICK1; DEA:=EMA(DIFF,13),COLORAADDFF,LINETHICK1; MACD:=2*(DIFF-DEA),COLORSTICK; TYP:=(HIGH+LOW+CLOSE)/3; CCI:=(TYP-MA(TYP,14))/(0.015*AVEDEV(TYP,14)); AA:=CROSS(CCI,-70); MM:=MACD>REF(MACD,1) AND MACD>0 AND CLOSE>OPEN; DD:AA AND MM,NODRAW,COLORFFBBFF; MA1:=MA(CLOSE,5); MA3:=MA(CLOSE,20); 一穿三:=MA1>O AND MA2>O AND MA3>O AND MA1OPEN; 一穿三 AND DD ; DRAWTEXT(一穿三, DD*1.13,'←致命出击II代'),COLORYELLOW;

解答：

?DIFF:=EMA(CLOSE,34)-EMA(CLOSE,55);

DEA:=EMA(DIFF,13);
