Прошу помочь с написанием индикатора (конверт с глаженый через ЕМА) формула из метастока EMA:=Input("Base EMA",1,100,22); Factor:=Input("Factor",1,50,27); avg:=Mov(C,EMA,E); csize:= Stdev(2*Max(Abs(H-avg) ,Abs(L-avg)) / avg,100)*Factor/10; {Use 100 days for stable channel size - default is 2.7 std} Csize:= ValueWhen(1, DayOfWeek()<Ref(DayOfWeek() ,-1) OR ( DayOfWeek()=Ref(DayOfWeek(),-1) AND DayOfMonth() <> Ref(DayOfMonth(),-1)) ,Ref(csize,-1)); { This pegs the Stdev to last bar of week and only changes once per week} csize:=LastValue(csize); {fix to constant using last value} channel:=csize*avg; avg+channel/2; avg-channel/2; avg;
