Quote from Redneck:
Could also be on rising, or high(er) volume â where sellers are scrambling to get out / and eager buyers are entering
Could be. However, your proposition was that the volume spike was on the downside. If as you say volume is also high on the upside, then your scenario is legitimate. And kudos to buyers for being able to work their way through all of that (I should also point out that sellers may be somewhat taken aback by the intensity of the buying and think that maybe they had it wrong and become buyers themselves; this also contributes to high volume).
This is part of the "story", and if one can view it in these terms rather than whether or not a green line has crossed a red line, he will be far more likely to make the best decision when the road price is traveling to the upside gets a little bumpy.
