分享一个自用的趋势副图，很精准，无未来函数！指标未加密，公开源码！
使用方法：
出现箭头买入；持续出现红柱就持仓；红柱转绿就卖出！
RSV1:=(CLOSE-LLV(LOW,7))/(HHV(HIGH,7)-LLV(LOW,7))*100;
RSV2:=(CLOSE-LLV(LOW,38))/(HHV(HIGH,38)-LLV(LOW,38))*100;
T1:SMA(RSV2,5,1),COLORRED,LINETHICK2;
T2:SMA(T1,10,1),COLORGREEN;
STICKLINE(T1>T2,T1,T2,1,0),COLORRED;
STICKLINE(T1<=T2,T1,T2,1,0),COLORGREEN;
XG:CROSS(T1,T2),LINETHICK0;
DRAWICON(XG,T1,1),COLORYELLOW;
