急急请高手帮忙 组合通达信的选股公式和预警公式 （主力介入选股 去）

pn1:=dynainfo(8)>0;pn2:=dynainfo(17)>0;pn3:=dynainfo(22)>0;pn4:=dynainfo(23)>0;st:=if(namelike('st')=1,0,if(namelike('s
st')=1,0,if(namelike('*st')=1,0,1)));
去除:=
pn1*pn2*pn3*pn4*st;
{只选非st类和当天非停牌的股------用于配合选股公式};diff:=ema(close,3)-ema(close,8);x1:=ema(diff,5)*5;x2:=((ema(close,3)-ema(close,8)))*5;zrxg1:=cross(x2,x1)
