将主力成本线主图中主力成本线上穿CB90改为选股公式,谢谢!

主力成本线主图原码如下(同花顺测试通过):

sm01:SUM(CLOSE*VOL*100,5)/SUM(VOL*100,5);

SM1:=INTPART(sm01*100)/100;

sm02:SUM(CLOSE*VOL*100,10)/SUM(VOL*100,10);

SM2:=INTPART(sm02*100)/100;

sm03:SUM(CLOSE*VOL*100,30)/SUM(VOL*100,30);

SM3:=INTPART(sm03*100)/100;

Var4:=REF(LOW,1)/LOW;

Var5:=EMA(Var4,13)/Var4*CLOSE;

VarA:=EMA(Var5,21)*1.17;

VarB:=EMA(Var5,21)*0.955;

VarC:=EMA(HIGH,21)/HIGH*CLOSE;

CB50:EMA(COST(50),7),colorwhite,POINTDOT;

CB70:EMA(COST(70),7),coloraaff12,POINTDOT;

CB75:EMA(COST(75),7),colorffaaaa;

CB80:EMA(COST(80),7),colorddffaa,POINTDOT;

CB1_85:EMA(COST(85),7),colorred;

cb90:EMA(COST(90),7),colorfaaaff;

CB2_15:EMA(COST(15),7),colorgreen;

警戒:EMA(VarC,21)*1.18,coloryellow,POINTDOT;




解答如下：
SM01:=SUM(CLOSE*VOL*100,5)/SUM(VOL*100,5);

CB90:=EMA(COST(90),7);

CROSS(SM01,CB90);
