Value Area is the price range where approximately 70% of a session’s volume traded, bounded above by the Value Area High (VAH) and below by the Value Area Low (VAL). Developed by J. Peter Steidlmayer at the Chicago Board of Trade in 1984, these levels — along with the Point of Control (POC) — have become standard reference points for futures and equities day traders building intraday trade plans around volume profile analysis.
Key Takeaways
- The Value Area contains ~70% of session volume; VAH is resistance, VAL is support when price trades inside the range — roles flip on breakouts.
- The 80% rule: when ES or NQ opens outside the prior day’s Value Area and re-enters, rotation to the opposite boundary completes ~80% of sessions.
- A naked POC — a prior session’s highest-volume price level never revisited — is one of the highest-probability magnetic targets in market profile trading.
How Value Area Works
The Value Area comes from Market Profile theory. After each session, a volume profile tool plots the volume traded at every price level. The algorithm then identifies the Point of Control — the single price with the most volume — and expands outward from the POC, adding price levels on either side until the cumulative volume reaches 70% of the session total. The upper boundary of that 70% range is the VAH; the lower boundary is the VAL.
VAH and VAL as dynamic levels:
- When price is trading inside the Value Area, VAH acts as resistance and VAL acts as support.
- When price breaks above VAH with conviction, VAH flips to support; when it breaks below VAL, VAL flips to resistance.
- The POC is the strongest gravitational center — price frequently revisits it multiple times within a session.
Profile shape adds context. A P-shaped profile (heavy volume at the top) indicates short covering: sellers who chased price down were forced to buy back. A B-shaped profile (heavy volume at the bottom) suggests accumulation. A balanced, bell-curve profile indicates a neutral auction day with no directional conviction. Reading the shape tells you whether the prior session’s Value Area is likely to hold or be violated.
Volume Profile vs. TPO Profile: Volume-based profiles (used on TradingView and ThinkOrSwim) weight levels by contracts traded — more relevant for equities and crypto. Time-Price-Opportunity (TPO) profiles weight by time spent at each price, preferred by pit-trained futures traders following Steidlmayer’s original methodology. Both produce VAH, VAL, and POC, but at different levels on volatile days.
Practical Example
Prior day’s ES (S&P 500 E-mini futures) closes with these levels: VAL = 5,210, POC = 5,225, VAH = 5,238.
The next morning, ES opens at 5,205 — 5 points below VAL. This triggers the 80% rule setup.
A trader waits for two consecutive 30-minute bars to close back above 5,210, confirming acceptance inside the Value Area. Once that confirmation prints:
- Entry: 5,212
- Stop: Below the overnight low at 5,198 (14-point risk = $700 per contract)
- Target 1: POC at 5,225 (+13 points = $650 per contract)
- Target 2: VAH at 5,238 (+26 points = $1,300 per contract)
- Risk/reward to T2: approximately 1:1.85
If ES instead opens inside the Value Area at 5,220, no 80% rule setup exists. In that case, traders treat VAH (5,238) and VAL (5,210) as a bracket — fading moves toward extremes or waiting for a high-volume breakout above VAH or below VAL to trade in the direction of expansion.
The Value Area is the price range where roughly 70 percent of a session’s volume traded. Its upper and lower boundaries — VAH and VAL — act as support and resistance. When price opens outside these levels and moves back in, it tends to rotate to the opposite side.
Common Mistakes
- Treating VAH/VAL as hard lines. These are zones, not exact price triggers. Waiting for bar-close acceptance above or below the level filters false signals caused by single wicks.
- Using distorted profiles. Thin overnight sessions produce abnormal volume distributions. A profile built on low-volume globex data will have a misleading VAH, VAL, and POC. Always check the session type before relying on the levels.
- Ignoring profile shape. Applying the same setup to a P-shaped profile (likely to reject higher prices) as to a B-shaped profile (likely to attract buying) leads to incorrect directional bias.
- Missing naked POCs. Traders who only watch the current session’s levels overlook naked POCs from prior sessions — often the highest-conviction magnet targets on the chart. A naked POC from three sessions ago that NQ has never revisited can be more powerful than the current day’s VAH.
How JournalPlus Tracks Value Area
JournalPlus lets traders tag each trade with the market structure context — including whether the entry was a VAH/VAL fade, an 80% rule setup, or a naked POC target. Over time, the journal surfaces which Value Area setups have the strongest edge in your trading, filtered by instrument, session type, and profile shape, so you can size those setups with confidence.
