Great observation. Last night while I was in bed trying to fall asleep, I was thinking about the same thing. The key here is how the adv-decl volume lines are computed. Like you said, if we gap considerably lower, all the volume will be tagged as "declining" volume as long as stocks are trading at a price < previous day's close. Here is an example: if we have a big downgap - say -2% on average for most stocks - and stocks start to rise or accumulate shortly after the open...well, the adv-decl volume lines will keep showing "bearish" volume until the gap is filled and most stocks get back in the green. Yesterday was a perfect example for this scenario: we gapped considerably lower, adv-decl volume lines showed "bearish" volume...yet we hit a bottom shortly after 11:00am ET and even rallied off that. Guess what? The adv-decl volume lines still showed "bearish" volume. Why? Because most stocks couldn't make it back to prior day's closing prices. In conclusion, the adv-decl volume lines can be a misleading indicator unless you associate it to what price is doing. Unfortunately I am not familiar with ELD programming - I use Tradestation - but if anyone is good at it, maybe we could tweak the current adv-decl volume lines to show what volume is doing from 9:30am ET inconsiderate of the gap. I am sure it won't take a rocket scientist to get the adv-decl volume lines to compute volume outside the opening gaps. If anyone is interested and skilled in programming, we could get a more reliable indicator that tells the real story.
