我优化的相对强弱指数 RSI

LC := REF(CLOSE,1);
RSV:=(CLOSE-LLV(LOW,18))/(HHV(HIGH,18)-LLV(LOW,18))*100;
K:=SMA(RSV,4,1);
D:=SMA(K,3,1);
J:=(3*K-2*D),coloryellow;
RSI1:=j+SMA(MAX(CLOSE-LC,0),5,1)/SMA(ABS(CLOSE-LC),5,1)*100;
rsi:ma(rsi1,3),colorred;
底:25,linethick2,COLorred;
分界:90,linethick2,COLORFF00FF;
顶:180,linethick2,COLOR00FF00;
跑:190,linethick2,COLORYELLOW;
DRAWTEXT(CROSS(180,rsi),180,'顶'),color00ff00;
DRAWTEXT(CROSS(rsi,90) and rsi>ref(rsi,1),90,'加仓'),colorred;
DRAWTEXT(CROSS(rsi,25),25,'买底'),color00ff00;
