DALE    —  !KELTNER  BANDS:
!Coded by: Rich Denning 8/28/05

! For the top or Plus Band, the ATR is calculated over 10 periods, 
! doubled and added to a 20 period exponential moving average 
! For the bottom or Minus Band, the ATR is calculated over 10 periods, 
! doubles and subtracted from a 20 period exponential moving average 


!CODING ABBREVIATIONS:
H	is [high].
L	is [low].
C	is [close].
C1	is val([close],1).

TR 	is Max(H - L,max(abs(C1 - L),abs(C1- H))).
ATR10	is expAvg(TR,10).

ESA20	is expavg(C,20).

KTop	is ESA20 + 2* ATR10.
KBot	is ESA20 - 2 * ATR10.

!! Plot KTop and KBot as two separate single line indicators on upper chart.
