把K线对应紫色区域做个选股

编写要求：

源码： RSV:=(C-LLV(L,9))/(HHV(H,9)-LLV(L,9))*100; K:=SMA(RSV,9,1); D:=SMA(K,9,1); J:3*K-2*D,COLOR00FFFF,LINETHICK2; IF(J>=REF(J,1),J,DRAWNULL),COLORFF00FF,LINETHICK2; 麻烦老师：只要是紫色区域全选出来做(海选）

股票网解答：

RSV:=(C-LLV(L,9))/(HHV(H,9)-LLV(L,9))*100;

K:=SMA(RSV,9,1);

D:=SMA(K,9,1);

J:=3*K-2*D,COLOR00FFFF,LINETHICK2;

J>=REF(J,1);
