将变盘公式中“出现红色箭头”时做个选股

编写要求：

源码如下： VAR1:=LLV(LOW,13); VAR2:=HHV(HIGH,13); VAR3:=SMA((CLOSE-VAR1)/(VAR2-VAR1)*100,5,1); VAR4:=SMA((VAR2-CLOSE)/(VAR2-VAR1)*100,5,1); DRAWBAND(VAR3,RGB(155,50,50),50,RGB(0,100,50)); 主力:VAR3,COLORRED; 散户:VAR4,COLORGREEN; VAR5:=SMA(MAX(CLOSE-REF(CLOSE,1),0),5,1)/SMA(ABS(CLOSE-REF(CLOSE,1)),5,1)*100; 操作:=EMA(VAR5,3),COLORYELLOW; STICKLINE(C,90,90,1,0),COLOR3C3CFF; STICKLINE(C,50,50,1,0),COLORYELLOW; STICKLINE(C,10,10,1,0),COLORCYAN; N1:=7; 界:=38,COLORFF3311; 加仓线:=51,COLORFF1155; LC:=REF(CLOSE,1); X:SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*100,COLORFFFFFF; 魔鬼:=DRAWLINE(X>=HHV(X,N1),X,X<=LLV(X,N1),X,1),COLOR00FF00; TJ1:=X=魔鬼; TJ2:=X

解答：

?N1:=7;

LC:=REF(CLOSE,1);?
