把神话测顶底公式中的顶和底信号分开提示

下面的公式中顶和底是一个信号，哪位老师给改一下，谢谢了
飞狐源码：

DRAWTEXT(FILTER(CLOSE>0,480),95,'无心插柳,柳成荫');
DRAWTEXT(FILTER(CLOSE>0,480),80,'有心栽花,花不开');
A:=LN(CLOSE)+LLV(LOW,55);
B:=SQRT(CLOSE)+LLV(LOW,55);
A1:=HHV(HIGH,55)-LN(CLOSE);
AB:=MA(CLOSE,21);
AA:IF(crOSS(A1,A),80,0);
DRAWTEXT(AA AND AB<REF(AB,5),75,'底');
DRAWTEXT(AA AND AB>REF(AB,5),75,'顶');
 

{DRAWTEXT(FILTER(CLOSE>0,480),95,'无心插柳,柳成荫');
DRAWTEXT(FILTER(CLOSE>0,480),80,'有心栽花,花不开')};
A:=LN(CLOSE)+LLV(LOW,55);
B:=SQRT(CLOSE)+LLV(LOW,55);
A1:=HHV(HIGH,55)-LN(CLOSE);
AB:=MA(CLOSE,21);
AA:=IF(CROSS(A1,A),80,0);
CC:AA AND AB<REF(AB,5),COLORRED;
DD:AA AND AB>REF(AB,5),COLORGREEN;
DRAWTEXT(CC,1,'底'),COLORRED;
DRAWTEXT(DD,2,'顶'),COLORGREEN;
