Market Profile
Quick Definition
A charting method that organizes price and time data into a bell-curve distribution, showing where the most trading activity occurred at each price level.
Key Takeaways
- Market Profile shows where the most trading activity occurred using time-based distributions, not just price.
- The Value Area (70% of activity) and Point of Control (highest activity price) define key levels for trading.
- Profile shapes reveal market conditions: bell curve = balanced, elongated = trending, bimodal = transitioning.
What Is Market Profile?
Market Profile is an analytical charting technique developed by J. Peter Steidlmayer at the Chicago Board of Trade (CBOT) in the 1980s. Instead of traditional time-based charts, Market Profile organizes trading activity into a statistical distribution showing where the market spent the most time at various price levels. The chart uses Time Price Opportunities (TPOs) — letters assigned to each 30-minute bracket — to build a profile that typically forms a bell curve. Key concepts include: Value Area (the price range where approximately 70% of trading occurred, representing fair value), Point of Control (POC — the single price with the highest activity), and Initial Balance (the range established in the first hour of trading). The profile shape reveals market structure: a normal distribution suggests balanced two-way trading, an elongated profile indicates trending behavior, and a profile with two humps (bimodal) shows the market split between two value areas. Professional traders use Market Profile to identify where institutional volume concentrated, find support and resistance based on volume rather than price alone, and determine whether the market is in balance (range-bound) or imbalance (trending).
Market Profile Example
- 1The Market Profile showed a narrow value area at $152-$155, with the POC at $153.50 — when price broke below the value area low on the next session, it triggered a "value area rejection" sell signal.
- 2A bimodal Market Profile distribution indicated the market was transitioning between two value areas at $100 and $108 — the eventual break above $108 on high TPO count confirmed the new higher value.
