根据下面的薛丝指标写个选股公式

VAR2:=CLOSE*VOL; VAR3:=EMA((EMA(VAR2,3)/EMA(VOL,3)+EMA(VAR2,6)/EMA(VOL,6) +EMA(VAR2,12)/EMA(VOL,12)+EMA(VAR2,24)/EMA(VOL,24))/4,13); VAR4:=EMA(CLOSE,9); SUP:1.06*VAR3; SDN:VAR3*0.94; LUP:EMA(VAR4*1.14,5); LDN:EMA(VAR4*0.86,5); 要求当前股价上穿绿,黄,白,紫线,4种情况

爱约股解答：

{上穿绿线}

VAR4:=EMA(CLOSE,9);

LDN:cross(c,EMA(VAR4*0.86,5));

{上穿紫线}

VAR4:=EMA(CLOSE,9);

LUP:cross(c,EMA(VAR4*1.14,5));

{上穿黄线}

VAR2:=CLOSE*VOL;

VAR3:=EMA((EMA(VAR2,3)/EMA(VOL,3)+EMA(VAR2,6)/EMA(VOL,6)

+EMA(VAR2,12)/EMA(VOL,12)+EMA(VAR2,24)/EMA(VOL,24))/4,13);

VAR4:=EMA(CLOSE,9);

SDN:cross(c,VAR3*0.94);

{上穿白线}

VAR2:=CLOSE*VOL;

VAR3:=EMA((EMA(VAR2,3)/EMA(VOL,3)+EMA(VAR2,6)/EMA(VOL,6)

+EMA(VAR2,12)/EMA(VOL,12)+EMA(VAR2,24)/EMA(VOL,24))/4,13);
