Volume Profile: POC, VAH & VAL Trading
Learn to identify key price levels using Volume Profile - Point of Control, Value Area High/Low.
Key Takeaways
- Volume Profile shows traded volume at each price level, revealing fair value zones
- POC (Point of Control) is the highest volume price level - a magnet for price
- Value Area (70% of volume) defines the accepted trading range
- Naked POCs from previous sessions act as price magnets
What is Volume Profile?
Volume Profile is a charting study that displays trading activity over a specified time period at specific price levels. Unlike traditional volume bars (which show volume over time), Volume Profile shows volume at each price level - revealing where the most trading occurred.
Key Volume Profile Levels
Point of Control (POC)
The price level with the highest traded volume. The POC acts as a "fair value" price and often provides strong support/resistance.
- Magnet effect: Price tends to return to the POC
- Mean reversion: Prices far from POC often revert
Value Area (VA)
The range of prices where 70% of volume occurred. This represents the "accepted value" zone.
- VAH (Value Area High): Upper boundary of the value area
- VAL (Value Area Low): Lower boundary of the value area
Volume Profile Signals in EMMA
Above POC
Price is trading above the Point of Control, indicating bullish sentiment. Traders holding above POC have "fair value" supporting their positions.
Below POC
Price below POC suggests bearish control. Watch for rejection at POC as potential resistance.
POC Touch
Price has reached the Point of Control level. This often triggers:
- Mean reversion bounces (price reversing at POC)
- Breakout continuation if POC fails to hold
VAH Breakout / VAL Breakdown
Breaking out of the value area often leads to trend moves:
- VAH Breakout: Bullish - price escaping the value area to the upside
- VAL Breakdown: Bearish - price breaking down from value area
- Asian session: Often builds the initial range
- London open: Frequently tests and breaks Asian range
- US session: Highest volume, often retests London POCs
Key Parameters
| Parameter | Default | Description |
|---|---|---|
| VP Period | 20 days | Time period for Volume Profile calculation |
| POC Tolerance | 0.5% | How close price must be to POC to trigger "touch" signal |
Trading Strategies
Value Area Play
- If price opens inside the value area, expect range-bound action
- Trade bounces between VAH and VAL
- Watch for breakouts/breakdowns from the value area
POC Bounce/Rejection
- Wait for price to approach POC
- Look for reversal candlestick patterns
- Enter in the direction of the bounce with stop beyond POC
Tips for Volume Profile Trading
- Use appropriate timeframes: Daily VP for swing trades, intraday VP for day trades
- Previous day's POC: Yesterday's POC often acts as today's key level
- Composite profiles: Longer-term VP shows more significant levels
- Naked POCs: Untested POCs from previous sessions are magnets for price
