Volume profile is a charting tool that shows how much volume traded at each price level over a specified period. Unlike traditional volume bars, it shows volume by price, not by time.
Volume Profile vs Traditional Volume
| Feature | Volume Bars | Volume Profile |
|---|
| Axis | Volume over time | Volume by price level |
| Shows | How much volume per period | Where volume concentrated |
| Best for | Momentum | Key price levels |
| Horizontal | No | Yes (on the side) |
Key Concepts
| Concept | Definition | Significance |
|---|
| Point of Control (POC) | Price level with highest volume | Strongest support/resistance |
| Value Area (VA) | Where 70% of volume occurred | Fair value range |
| Value Area High (VAH) | Top of value area | Resistance |
| Value Area Low (VAL) | Bottom of value area | Support |
| High Volume Node (HVN) | High trading activity | Support/resistance zone |
| Low Volume Node (LVN) | Low trading activity | Gap — price moves fast through |
How to Interpret
Point of Control (POC)
The POC is the price where the most trading occurred.
| POC Location | Meaning |
|---|
| Price above POC | Bullish — POC becomes support |
| Price below POC | Bearish — POC becomes resistance |
| Multiple POCs | Several key levels |
Value Area
The range containing 70% of volume (typically the mean ± 1 standard deviation).
| Price vs Value Area | Meaning |
|---|
| Above VAH | Extended — may pull back |
| Below VAL | Extended — may bounce |
| Within VA | Fair value — chop |
High Volume Nodes
Areas where significant trading occurred. Price tends to respect these levels.
Low Volume Nodes
Areas with minimal trading (gaps). Price moves quickly through these levels.
Trading Strategies
POC Bounce
| Setup | Action |
|---|
| Price approaches POC from above | Buy at POC, stop below |
| Price approaches POC from below | Sell at POC, stop above |
Value Area Breakout
| Setup | Action |
|---|
| Price breaks above VAH with volume | Buy breakout |
| Price breaks below VAL with volume | Sell breakout |
LVN Gap Trade
| Setup | Action |
|---|
| Price approaching LVN | Expect fast move through level |
| After LVN break | Expect continuation |
| Tool | How to Combine |
|---|
| Support/resistance | Use POC and VA for key levels |
| Moving averages | Volume at MA = strong reaction |
| RSI | Volume profile + RSI divergence = strong reversal |
| Market structure | POC at swing high/low = significant |
Timeframe Considerations
| Timeframe | Volume Profile Period | Best For |
|---|
| Day trading | Current session | Intraday levels |
| Swing trading | 5-10 days | Medium-term levels |
| Position trading | 30-90 days | Major support/resistance |
Bottom Line
Volume profile reveals where market participants are most active. The POC and value area are powerful support and resistance levels. Use them to identify high-probability entry zones, avoid trading in low-volume gaps, and confirm breakouts with above-average volume at the VAH or VAL break.
