考夫曼自适应均线

根据价格运动效率自适应调节加权系数, 比固定周期的均线更适合于趋势跟踪.

input:n1(8);
n:=if(barpos<=n1,barpos-1,n1);
direction:=c-ref(c,n);
volatility:=sum(abs(c-ref(c,1)),n);
ER:=direction/volatility;
smooth:=if(barpos=1,1,ER*0.6022+0.0645);
cc:=smooth*smooth;
ama:dma(c,cc);

 

 

发现设置2条考夫曼自适应均线时，改变其中一条均线的参数时，另外的一条均线也会跟着改变的（这条的参数没有变动过）
不知是怎样回事，会影响其它均线的值？
input:n1(8);
n:=if(barpos<=n1,barpos-1,n1);
direction:=c-ref(c,n);
volatility:=sum(abs(c-ref(c,1)),n);
ER:=direction/volatility;
smooth:=if(barpos=1,1,ER*0.6022+0.0645);
cc:=smooth*smooth;
ama:dma(c,cc),LINETHICK0;
PARTLINE(ama>=ref(ama,1),ama),COLORRED,LINETHICK2;
PARTLINE(ama<ref(ama,1),ama),COLORWHITE,LINETHICK2;
input:n2(30);{改变其值时，上面的AMA均线值也会变}
nn:=if(barpos<=n2,barpos-1,n2);
direction1:=c-ref(c,nn);
volatility1:=sum(abs(c-ref(c,1)),n);
ER1:=direction1/volatility1;
smooth1:=if(barpos=1,1,ER1*0.6022+0.0645);
cc1:=smooth1*smooth1;
ama1:dma(c,cc1),LINETHICK0;
PARTLINE(ama1>=ref(ama1,1),ama1),COLORMAGENTA,LINETHICK2;
PARTLINE(ama1<ref(ama1,1),ama1),COLORBLUE,LINETHICK2;
