Volume Profile
A horizontal histogram showing how much volume traded at each price level — revealing where markets have accepted or rejected value, not just when.
Description
Volume Profile differs fundamentally from time-based volume: instead of asking “how much traded per time period,” it asks “how much traded at each price level.” The result is a horizontal histogram anchored to the price axis, showing the market’s price acceptance profile over a selected range. High Volume Nodes (HVN) are prices with heavy acceptance; Low Volume Nodes (LVN) are prices that the market moved through quickly.
How It Works
For a selected time range, all executed transactions are allocated to their respective price levels. The resulting histogram is plotted horizontally — wider bars indicate more volume at that price. The Point of Control (POC) is the single price level with the highest volume. The Value Area spans the price range containing 70% of all volume — typically the POC ± about one standard deviation.
How to Read It
Price tends to slow, consolidate, or reverse at HVNs because that’s where the most participants entered — they defend their positions. Price tends to move quickly through LVNs because those levels have thin support. The Value Area High (VAH) and Value Area Low (VAL) are key support/resistance. A break through the Value Area into a LVN often signals fast price movement.
Common Uses
- Identifying high-conviction support and resistance levels
- Locating POC as a magnet for price returns
- Assessing where institutional orders were placed
- Finding LVN targets for breakout moves
Caveats
Volume Profile requires specific software and data capabilities not available on all platforms. The selected time range dramatically affects the resulting profile — a daily profile looks very different from a monthly one. On thinly traded instruments, volume data is unreliable, making the profile misleading. Interpretation requires experience; the visual complexity can lead to confirmation bias in selecting which nodes to focus on.
