【飞狐】请改成画线随着光标移动，谢谢！！

心诚

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=SMA(RSV,3,1);
D:=SMA(K,3,1);
J:=3*K-2*D;
t:=BARSLAST(CROSS(d,k));
a:=REF(HHV(HIGH,5),t);
b:a[DATACOUNT],COLORCYAN,LINETHICK1;

方天问

随光标移动有什么意义，直接历史的线显示出来
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=SMA(RSV,3,1);
D:=SMA(K,3,1);
J:=3*K-2*D;
t:=BARSLAST(CROSS(d,k));
a:REF(HHV(HIGH,5),t),COLORCYAN;
