Value Area
VAThe price zone where roughly 70% of a period's volume traded — the range institutions treat as fair, forming natural support and resistance.
Key insightPrice that leaves the value area returns to test its edge about 80% of the time.
Value-area trading system
Trade where value actually lives.
Institutional-grade volume-profile analysis — value areas, market tension, and the 80% rule — distilled into high-probability breakout setups across equities, futures, and options.

Origins
Born in the Chicago pits.
Value-area analysis was forged in the 1980s trading pits of Chicago, where floor traders noticed that roughly 70% of the day's volume changed hands inside a narrow band of prices — the range the market treated as fair. That band became the value area.
Those pit observations were formalized into Market Profile by J. Peter Steidlmayer at the Chicago Board of Trade. What began as chalk marks on a trading card is now the volume-profile engine behind this system.

The concepts
A working vocabulary of value.
Every setup is built from six ideas about where volume concentrates — and what price does when it leaves.
Explosive Moves
BREAKOUTA decisive break out of an established value area on heavy volume. Each break is scored on volume, structure, and historical follow-through.
Scoring90%+ perfect storm · 75–89% high probability · 60–74% moderate.
Market Tension
TENSIONThe compression of price inside the value area — coiled energy, like a spring held down before it releases into expansion.
LevelsEXTREME › HIGH › MODERATE › LOW. Higher tension, bigger release.
The 80% Rule
80% RULEWhen price moves outside the value area, it has roughly an 80% chance of returning to test the boundary before continuing on.
AppliedDrives entry timing, stop placement, and where to take profit.
Breakout Probability
P(BREAK)A composite read of volume profile, structure, historical pattern, and market state — expressed as the odds a break actually holds.
Confirms onClean structure, volume expansion, and follow-through momentum.
Point of Control
POCThe single price with the most traded volume in the profile — the strongest magnet, and a decisive support/resistance level in later sessions.
