求根据下面的指标增加一个出空的“*”信号吗

VAR2:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;

VAR3:=SMA(SMA(VAR2,3,1),3,1)/30;

VAR4:=EMA(VAR3,5);

VAR5:=3*VAR3-2*VAR4;

AA:=CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O;

VAR6:=(2*CLOSE+HIGH+LOW)/4;

VAR7:=LLV(LOW,22);

VAR8:=HHV(HIGH,22);

VAR9:=EMA((VAR6-VAR7)/(VAR8-VAR7)*100,13);

VARA:=EMA(0.667*REF(VAR9,1)+0.333*VAR9,2);

STICKLINE(VAR9>VARA,VAR9,VARA,4,1), COLORMAGENTA;

STICKLINE(VAR9<=VARA,VAR9,VARA,4,1), COLORFFCC66;

STICKLINE(CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O,VAR9,VARA,1,0),COLORRED;

DRAWTEXT(CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O,8,'*'),COLORRED;

DRAWTEXT(CROSS(VAR5,VAR3) AND VAR3>2.1 AND C<0,88,'*'),COLORYELLOW;

趋势: EMA(0.382*REF(VAR9,2)+0.618*VAR9,6);

获利可抛:50,COLORWHITE;

抄底区:20,COLORGREEN;

卖空区:80,COLORYELLOW;
