This one is still eluding me, weakness could be a climactic volume before moving back into the range, or just an upwave with less volume after a climactic move. Or it could be that volume rose before or at the break, but then stalled before the reversal.
For example, I took this chart from the Trading the NQ forum:
We come from a strong uptrend after the break of the lower range, there is an upside break where demand dried up earlier in the morning, but then comes the very clear reversal in hindsight. If I was looking at this in real time I would have been thinking that the most probable scenario would be a breakout and that the lower volume bar was the retracement (test) before the confirmation. So here is where I think I am missing the volume analysis bigtime.

Something to consider is using the terms demand and supply. They can refer to being long or short in price. However, when you consider that any initiated short position is a stop away from being long as well as any initiated long position is a stop away from being a seller, demand and supply is more accurately describing liquidity. The offering of trading options to other traders when one places open limit orders (supply) and the role of market orders when traders are time sensitive on liquidity (demand).
When observing volume, demand (for time sensitive trading) is the volume of transactions where there is agreement to do business. When there is no-agreement to do business at the current price levels, the supply of open limit orders might fluctuate but it's the market orders entering the market that initiates a move contra to the Dominant trend.
DU (Dry up) volume is the shortest volume bar on one's display in the timeframe one is observing. Long and short volume had a behavior prior to this moment and will exhibit a different behavior post this moment.
