爱约股解答：

input:p(1.5,1,4),m(10,3,50);

atr:=if(barssince(c)>=m,ma(tr,m),ema(tr,m));

median:=(high + low)/2;

up:=median + atr*p;

dn:=median - atr*p;

trup:=llv(up,m);

trdn:=hhv(dn,m);

fc:=close;

for i=m+1 to datacount do begin

if fc[i] > trup[i-1] then

tra[i]:=1;else

if fc[i] < trdn[i-1] then

tra[i]:=-1;else

tra[i]:=tra[i-1];

end;

partline(tra=-1,trup),colorblue,linethick2;

partline(tra=1,trdn),colormagenta,linethick2;

趋势跟踪止损线:if(tra=1,trdn,trup),linethick;
