做个红箭头出现的选股公式

编写条件：

RSV:=(CLOSE-LLV(LOW,6))/(HHV(HIGH,6)-LLV(LOW,9))*3; K:=SMA(RSV,3,1); D:=SMA(K,3,1); J:=3*K-2*D; N:=7; A2:=DRAWLINE(J<=LLV(J,N),J,J>=HHV(J,N),J,0); A3:=J=A2; A5:=J编写方法：

&nbsp;RSV:=(CLOSE-LLV(LOW,6))/(HHV(HIGH,6)-LLV(LOW,9))*3;

K:=SMA(RSV,3,1);

D:=SMA(K,3,1);

J:=3*K-2*D;

N:=7;

A2:=DRAWLINE(J<=LLV(J,N),J,J>=HHV(J,N),J,0);

A3:=J=A2;

A5:=J<REF(J,1);

FILTER(A3 AND A5,1);
