将副图做一个选股公式出现红箭头、白箭头

副图源码：

JX1:=MA(C,5);
JX2:=MA(C,10);
JX3:=MA(C,20);
JTTJ1:=BARSLAST(CROSS(JX1,JX2));
JTTJ2:=BARSLAST(CROSS(JX1,JX3));
JTTJ3:=BARSLAST(CROSS(JX2,JX3));
JTTJ4:=JTTJ1>=JTTJ2;
JTTJ5:=JTTJ2>=JTTJ3;
JTTJ6:=JTTJ3=0;
价托:JTTJ4 AND JTTJ5 AND JTTJ6;
BOLL:=MA(CLOSE,20);
UPPER:=BOLL+2*STD(CLOSE,20);
LOWER:=BOLL-2*STD(CLOSE,20);
大黑马:CROSS(C,UPPER) AND C/REF(C,1)>1.05,COLORRED;

BOLL:=MA(CLOSE,20);
UPPER:=BOLL+2*STD(CLOSE,20);
红箭头:CROSS(C,UPPER) AND C/REF(C,1)>1.05;
