请高手帮忙 组合通达信的选股公式和预警公式 牛资

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) AND X2>0;LC:=REF(CLOSE,1);SG:=EMA(HHV(HIGH,1),8);XX1:=EMA(CLOSE,8);X30:=((XX1 < REF(XX1,1)) AND (CLOSE 震仓线 ;PP3:=操作线<抄底线 AND REF(操作线,1)>抄底线;抓牛:=(((((COUNT((X31 = 1),4) = 3) AND (X31 = 0))AND O0.035))*89) >=89)OR((C-REF(C,1))/REF(C,1)>0.035 AND (REF(PP3,1) OR REF(PP,1))) ;XG:ZRXG1 AND 抓牛 AND 去除;

(这个公式是两个条件都满足的选股)
