!! An EDS pseudo-equivalent of the AIQ OBV indicator.
!! Identical in shape of plot only, not in value.
!! Coded by Bill S.  on 09/26/2003. 
!!============================================. 
period is HasDataFor(10000).
cl is [close].
ycl is val([close],1).
OBVvol is [volume] / 1000.
F is iff(cl > ycl,1,iff(cl<ycl,-1,0)).
VolSum is Sum(OBVvol *F, period).
VolSumSeed is 1000 + VolSum.
 
OBVeds is iff( FirstDataDate() >= Reportdate(),1000,VolSumSeed).
