短买出现时做个选股公式

原公式：

AAA:=(3*C+H+L+O)/6;
 VAR1:=(8*AAA+7*REF(AAA,1)+6*REF(AAA,2)+5*REF(AAA,3)+4*REF(AAA,4)+3*REF(AAA,5)+2*REF(AAA,6)+REF(AAA,8))/36;
 VAR2:=(HHV(VAR1,5)+HHV(VAR1,10)+HHV(VAR1,20))/3;
 VAR3:=(LLV(VAR1,5)+LLV(VAR1,10)+LLV(VAR1,20))/3;
 VAR4:=(HHV(VAR2,5)+HHV(VAR2,10)+HHV(VAR2,20))/3;
 VAR5:=(LLV(VAR3,5)+LLV(VAR3,10)+LLV(VAR3,20))/3;
 VAR6:=(LLV(VAR1,2)+LLV(VAR1,4)+LLV(VAR1,6))/3;
 DRAWBAND(VAR1,RGB(155,50,50),VAR6,RGB(250,250,0));
 短线:VAR1,COLORWHITE;
 中线:VAR6,COLORYELLOW;
 下跌:IF(VAR1=VAR6,VAR6,DRAWNULL),COLORGREEN;
 DRAWTEXT(O<中线 AND C>短线 AND REF(C,1)<下跌,L*0.99,'短买');
