Nice call Cookie! I've been working on VCR bottom detecting, and have found that qualifying it with positive OBV over the previous 3 days acts as a good check for true bottom. See attached chart, showing 3 neg OBV's, and the current pos(almost) 3 day OBV. I have also found that extaordinarily high volumes,may give rise to VCR peaks that may not be bottoms.These I have filtered out by comparing to ESA volume and restricting a valid peak to 8* ESA volume( 14 days)
