Without wanting to start an argument about the exact definition of these Bands... of which there appears to many, here is one version: --8<------------------------------------- {Simple Keltner Bands} len:= Input("Length",2,100,10); MA:=Mov((H+L+C)/3, len, S); x:=Mov((H-L), len,S); MA+x; {UpperKeltner Band} MA; {Moving Average} MA-x; {LowerKeltner Band} --8<------------------------------------- and here's another... --8<------------------------------------- {Variable Keltner Bands} prd1:= Input("EMA Periods",1,100,20); prd2:= Input("ATR Periods",1,100,20); multiplier:= Input("ATR Multiplier",1,10,1.5); x:=Input("Data: 1-O 2-H 3-L 4-C 5-MP 6-Typ",1,6,4); x:=If(x=1,O,If(x=2,H,If(x=3,L,If(x=4,C,If(x=5,MP(),Typical()))))); AV:= Mov(x,prd1,E); UL:= AV+ATR(prd2)*multiplier; LL:= AV-ATR(prd2)*multiplier; AV;UL;LL; --8<------------------------------------- I am sure there are plenty more out there too! Hope these help. wabbit :D

This indicator will allow you to plot the indicator from a higher time frame onto a lower time frame chart you will need the powerpivot Plus Add-on for this indicator to work x:=Input("Number of Periods", 2,500,21); Factor1:=Input("TFactor1", 0, 1000, 1); offset:=Input("Offset", 0, 1000, 0); HD:=ExtFml("PowerPivots.TDataCreate",1, factor1); LD:=ExtFml("PowerPivots.TDataCreate",2, factor1); CD:=ExtFml("PowerPivots.TDataCreate",3, factor1); A1:=Mov((HD+LD+CD)/3,x,S); A2:=Mov((HD+LD+CD)/3,x,S) + Mov((HD-LD),x,S); A3:=Mov((HD+LD+CD)/3,x,S) - Mov((HD-LD),x,S); A1:=ExtFml("PowerPivots.TDataLocalize", A1, factor1, offset); A2:=ExtFml("PowerPivots.TDataLocalize", A2, factor1, offset); A3:=ExtFml("PowerPivots.TDataLocalize", A3, factor1, offset); A1;A2;A3;
