I agree, OBV can be manipulated. Any time a stock is
around unchanged the last trade can determine whether
the whole days volume gets added or subtracted from the OBV.
So one single 100 share trade can shift the whole day's volume.

On Balance Volume
On balance volume is an accumulation of volume where: the current interval's volume is added to the total if the stock closes up, and today's volume is subtracted from the total if the stock closes down.
