Definition
Session range is a price-based measure that captures how far an asset’s price moved between the high and low within a defined trading session. A session can be any chosen block of time, such as a day, a specific market’s open hours, or a custom time window used for analysis. The session range is typically expressed in absolute price units, but it can also be viewed as a percentage of the starting or closing price.
In crypto markets, which trade continuously, traders often define sessions by time zones or by fixed intervals to make session ranges comparable. A wider session range usually indicates more active price movement during that period, while a narrow session range suggests relatively quiet trading conditions.
Context and Usage
Session range is commonly used as a basic way to observe market behavior and price expansion within a given period. It helps traders understand how much the market moved during that session, which can be relevant for approaches such as Range Trading. Because it reflects the spread between high and low prices, session range is closely related to the idea of Volatility, although it is a simpler, session-specific snapshot rather than a full statistical measure.
Market participants may compare session ranges across multiple periods to see whether price movement is expanding or contracting over time. In this way, session range serves as a foundational concept for interpreting how dynamic or subdued trading conditions are within each chosen session.
