出出现“区域底部”选股公式

源码如下：
STICKLINE(C>=O,H,L,0,0),COLORffffFF;
STICKLINE(C>=O,C,O,8,1),COLORffffFF;
STICKLINE(C<O,H,L,0,0),COLORB6B600;
STICKLINE(C<O,C,O,8,1),COLORB6B600;
B1:='--------------------财富平台';
DRAWTEXT(VOL=HHV(VOL,20),C ,B1),PXUP8,COLORRED;

VARM2:=(CLOSE-LLV(LOW,21))/(HHV(HIGH,21)-LLV(LOW,21))*100;
VARM3:=SMA(SMA(VARM2,9,4),9,4)/7.777777;
VARM4:=EMA(VARM3,5);
VARM5:=3*VARM3-2*VARM4;
AAM:=CROSS(VARM5,VARM3) AND VARM3<1.7777777 AND C>O;
VARM6:=(2*CLOSE+HIGH+LOW)/4;
VARM7:=LLV(LOW,13);
VARM8:=HHV(HIGH,13);
VARM9:=EMA((VARM6-VARM7)/(VARM8-VARM7)*100,13);
VARMA:=EMA(0.667*REF(VARM9,1)+0.333*VARM9,2);
DRAWTEXT(AAM,L,'区域底部'),COLORMAGENTA;

解答如下：

VARM2:=(CLOSE-LLV(LOW,21))/(HHV(HIGH,21)-LLV(LOW,21))*100;
VARM3:=SMA(SMA(VARM2,9,4),9,4)/7.777777;
VARM4:=EMA(VARM3,5);
VARM5:=3*VARM3-2*VARM4;
CROSS(VARM5,VARM3) AND VARM3<1.7777777 AND C>O;
