根據(jù)價格運動效率自適應(yīng)調(diào)節(jié)加權(quán)系數(shù), 比固定周期的均線更適合于趨勢跟蹤.

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);

 

 

發(fā)現(xiàn)設(shè)置2條考夫曼自適應(yīng)均線時，改變其中一條均線的參數(shù)時，另外的一條均線也會跟著改變的（這條的參數(shù)沒有變動過）
不知是怎樣回事，會影響其它均線的值？
input:n1(8);
n:=if(barpos<=n1,barpos-1,n1);
direction:=c-ref(c,n);

PARTLINE(ama<ref(ama,1),ama),COLORWHITE,LINETHICK2;
input:n2(30);{改變其值時，上面的AMA均線值也會變}
nn:=if(barpos<=n2,barpos-1,n2);
