将这个MACD公式改成通达信

编写要求：

DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26); DEA:=EMA(DIFF,9); MACD:2*(DIFF-DEA), COLORSTICK; MACD1:SMA(MACD,3,1); MACD2:SMA(MACD1,3,1); 中线:=EMA(SLOPE(C,21)*20+C,55); 短线:=MA(CLOSE-中线,5)+中线; 副线:=SMA(短线,3,1); UPR:=中线+3*STD(中线,10); DWN:=中线-3*STD(中线,10); 上:HHV(MACD,20),COLORGRAY,DOTLINE; 金叉:CROSS(副线,中线) AND 短线>=副线 AND BARSLAST(MACD=上)<=10,PRECIS0,LINETHICK0; drawbmp(金叉,0,'buy1.bmp'),align1,valign2; 准备区:last(中线>REF(中线,1) AND 副线>REF(副线,1) AND BARSLAST(金叉)<=10),COLOR00FFFF,PRECIS0,LINETHICK0; 窄:=(UPR-DWN)/DWN*100; 拐头:UPR>=REF(UPR,1) AND REF(UPR,1)=UPR AND 短线>=REF(短线,1) AND BARSLAST(窄=LLV(窄,30))<=5 AND BARSLAST(MACD=上)<=10,COLORYELLOW,PRECIS0,LINETHICK0; STICKLINE(拐头,MACD,0,8,1),COLORYELLOW,LINETHICK1; 操作区:last(短线>=UPR AND 中线>REF(中线,1) AND BARSLAST(拐头)<10),COLORRED,PRECIS0,LINETHICK0; 阴:=(LOW<=副线 AND CLOSE<短线) OR (CLOSE副线 AND REF(短线,1)<=REF(副线+0.01,1)) AND 短线>=中线 AND 中线>=REF(中线,1) AND MACD>=0 AND MACD1>=MACD2,PRECIS0,COLORWHITE,LINETHICK0; STICKLINE(交叉,MACD1,MACD2,3,0),COLORWHITE,LINETHICK1; 下:LLV(MACD,20),COLORCYAN,PRECIS2,DOTLINE; PARTLINE(上,MACD=上,RGB(255,255,255)); PARTLINE(MACD1,操作区,RGB(255,0,0)),LINETHICK2; PARTLINE(MACD1,准备区,RGB(255,255,255)),LINETHICK2; FILLRGN(0,MACD2,0>MACD2 AND 0副线 AND 中线+0.01<短线 AND BARSLAST(MACD=上)<=10,RGB(0,255,0)); 0,DOTLINE,PRECIS0;

解答：

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

DEA:=EMA(DIFF,9);
