可以使用自编指标将20-80区域填充颜色，20以下80以上用系统颜色
参考
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
BACKGROUNDSTYLE(1);
K:SMA(RSV,3,1);
D:SMA(K,3,1);
J:3*K-2*D;
FILLRGN(C>0,20,80,COLORLIGHTBLUE);
参考
LC := REF(CLOSE,1);
BACKGROUNDSTYLE(1);
RSI1:SMA(MAX(CLOSE-LC,0),7,1)/SMA(ABS(CLOSE-LC),7,1)*100;
RSI2:SMA(MAX(CLOSE-LC,0),14,1)/SMA(ABS(CLOSE-LC),14,1)*100;
FILLRGN(C>0,20,80,COLORLIGHTBLUE);//填充颜色

FILLRGN(C>0,20,80,RGB(192,192,192));//填充颜色
您可以在如下图位置选择颜色，插入自己需要的颜色
