这样的kdj才是我们想要的

公式原码如下：
hp:=hhv(h,9);
lp:=llv(l,9);
r:=(c-lp)/(hp-lp)*100;
k:sma(r,3,1),coloryellow,linethick2;
d:sma(k,3,1),colorwhite,linethick2;
j:3*k-2*d,colorff9999,linethick2;
m:=ma(r,40);
s:=std(r,40);
高:=m+2*s;
中:=m;
低:=m-2*s;
【高】: 高,color0099ff;
【中】: 中,pointdot,colorwhite;
【低】: 低,color00ff00;
drawtext(cross(高,j) ,j*1.2,'★'),coloryellow;
drawtext(cross(中,j) and m<=80 ,高,'抛'),colorred;
drawtext(cross(j,低) ,j,'▲'),color00ff00;
drawtext(cross(j,低) and k<10 ,j,'▲'),colorred;
drawtext(cross(j,中) and K>D ,0,'吸'),coloryellow;
drawtext(cross(d,k) and (d>m or d>=50),d,'★'),coloryellow;
drawtext(cross(d,k) and m>80,高,'逃顶'),coloryellow;
drawtext(cross(d,k) and d>85,d,'★'),colorred;
drawtext(cross(k,d) and d<15,d,'▲'),colorred;
drawtext(中>80 ,中,'★'),colorred;
