Volume Analysis

Direct Answer

Volume measures participation, not direction: it tells you how much trading produced a price move, never who was buying. Every share traded is both bought and sold, so volume alone cannot be attributed to either side. That single limitation defines every legitimate use of volume, confirming that a breakout had participation behind it, flagging a move that did not, and locating the price areas where the most trading has occurred.

Does high volume mean buying pressure?

No. Every share traded is both bought and sold, so volume alone cannot be attributed to either side. Indicators that appear to split volume into buying and selling infer it from where price closed within the bar's range, a reasonable heuristic, but an inference, and it is wrong in exactly the conditions where it matters most.
