怎样能选出总买量大于总卖量的股票

N1:=(1000);
Var3:=EMA(100*(CLOSE-LLV(LOW,100))/(HHV(HIGH,100)-LLV(LOW,100)),5);
Var4:=(CLOSE-LLV(CLOSE,N1))/(HHV(CLOSE,N1)-LLV(CLOSE,N1))*100;
Var5:=EMA(CLOSE,2)-EMA(CLOSE,150);
Var6:=EMA(Var5,100);
Var7:=2*(Var5-Var6);
Var8:=POW(Var7,3)*0.1+POW(Var7,1);
Var9:=SQRT(SQRT(LOW*HIGH*OPEN*CLOSE));
VarA:=EMA(Var9*0.97,3);
VarB:=(HIGH+LOW+CLOSE)/3;
VarC:=(VarB-MA(VarB,14))/(0.015*AVEDEV(VarB,14));
线:= IF(Var7>0.1,Var8,0)*5;
Var1A:=CROSS(线,2);
Var1B:=CROSS(线,4);
庄拉:=FILTER((Var1A OR Var1B) AND Var4<40 AND Var3<40,5)=1;
选股:庄拉;

工具---条件选股---技术指标---c多空势力对比指标---内外盘之差， 最后点执行选股。
祝你好运
