请老师帮忙设计一个expma即将金叉，但尚未金叉的选股公式，谢谢！

求大师帮忙编写一个通达信expma选股公式

EXP1:=EMA(CLOSE,12);

EXP2:=EMA(CLOSE,50);

XG:REF(EXP1,1)=REF(EXP1,2) AND REF(EXP1,2)REF(EXP1,1) AND EXP1>EXP2;

你要求条件走平，这个走平是极少出现的。这样选股很那选的出来。

VAR1:=EMA(CLOSE,2)-EMA(CLOSE,120);

VAR2:=EMA(VAR1,68);

VAR3:=(VAR1+VAR2);

关注:=POW(VAR3,3)*0.1+POW(VAR3,1);

核心:=EMA(关注,30);

涨停:=1;

敬:=涨停*核心/5;

耀:=MA(敬,6);

XG:CROSS(敬,耀);

VAR2:=REF(LOW,1);

VAR3:=SMA(ABS(LOW-VAR2),3,1)/SMA(MAX(LOW-VAR2,0),3,1)*100;

VAR4:=EMA(IF(CLOSE*1.2,VAR3*10,VAR3/10),3);

VAR5:=LLV(LOW,38);

VAR6:=HHV(VAR4,38);

VAR7:=IF(LLV(LOW,90),1,0);

VAR8:=EMA(IF(LOW<=VAR5,(VAR4+VAR6*2)/2,0),3)/618*VAR7;

DD:=VAR8>5;

买入:=IF((COUNT(DD,2)=2),-20,0);

VAR1S:=REF((LOW+OPEN+CLOSE+HIGH)/4,1);

VAR2S:=SMA(ABS(LOW-VAR1S),13,1)/SMA(MAX(LOW-VAR1S,0),10,1);

VAR3S:=EMA(VAR2S,10);

VAR4S:=LLV(LOW,33);

VAR5S:=EMA(IF(LOW<=VAR4S,VAR3S,0),3);

主力进场:=IF(VAR5S>REF(VAR5S,1),VAR5S,0)*1.1,LINETHICK1,COLOR00FFFF;

STICKLINE(VAR5S>REF(VAR5S,1),0,VAR5S,4,1 ),COLORRED;

洗盘:=IF(VAR5S<REF(VAR5S,1),VAR5S,0),COLORGREEN;

低买:CROSS(洗盘,主力进场)AND 买入=-20;

cross(ma1,ma2);
