**Volume is one of the clearest ways to read supply and demand, and it often reveals whether institutions are involved.**
When volume expands on up days and dries up on pullbacks, it usually signals strong demand and healthy sponsorship.
When a stock breaks out on weak volume, the move is more vulnerable because there is not enough conviction behind it.
For swing traders, volume helps confirm whether a move is being supported by real buying or just short-term noise.
It is one of the most useful filters for separating strong setups from weak ones.
