请高人帮我编写一个MACD 文华财经程序化交易的公式

//该模型仅仅用来示范如何根据指标编写简单的模型

//用户需要根据自己交易经验，进行修改后再实际应用!!!

DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG)

DEA : EMA(DIFF,M)

MACD:2*(DIFF-DEA),COLORSTICK

MACD<0 AND REF(MACD,1)<MACD,BPK

MACD>0 AND REF(MACD,1)>MACD,SPK

AUTOFILTER

这个模型问题在于，当红绿柱参差不齐的时候会发生频繁的反手买卖，所以实战上不建议，仅供参考。

DIFF:EMA(CLOSE,12)-EMA(CLOSE,27)

DEA:EMA(DIFF,9)

MACD:2*(DIFF-DEA), COLORSTICK,LINETHICK2

低位金叉:=CROSS(DIFF,DEA) AND DIFF<-0.1

STICKLINE(低位金叉,0,0.08,6,0),COLORYELLOW

DRAWTEXT(低位金叉,0.16,' 低位金叉'),COLORWHITE

JCCOUNT:=COUNT(CROSS(DIFF,DEA),BARSLAST(DEA>=0))

二次金叉:=CROSS(DIFF,DEA) AND DEA<0 AND COUNT(JCCOUNT=2,21)=1

STICKLINE(二次金叉,0,0.06,6,0),COLORFF00FF

DRAWICON(二次金叉,DEA*0.9,1)

DRAWTEXT(二次金叉,0.2,' 二次金叉'),COLORYELLOW

A1:=BARSLAST(REF(CROSS(DIFF,DEA),1))

底背离:=REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA)

STICKLINE(底背离,0,0.03,6,0),COLOR00FF00

底背:DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED,LINETHICK4

DRAWTEXT(底背离,0.12,' 底背离'),COLORFF00FF

A2:=BARSLAST(REF(CROSS(DEA,DIFF),1))

顶背离:=REF(CLOSE,A2+1)<CLOSE AND REF(DIFF,A2+1)>DIFF AND CROSS(DEA,DIFF)

顶背:DRAWLINE(A2=0,DEA,顶背离,DEA,0),COLORGREEN,LINETHICK4

DRAWTEXT(低位金叉 AND 二次金叉 AND 底背离,0.25,'三全项'),COLOR0000FF,LINETHICK2
