Relative Volume (RVOL) compares the current trading volume to the average volume for the same time period, expressed as a ratio. An RVOL of 2.0 means volume is twice the normal level, signaling unusual activity that often precedes significant price moves or confirms the strength of an ongoing move.
Raw volume numbers are difficult to compare across different assets and timeframes. A volume of 10 million on Bitcoin means something very different than 10 million on a small-cap altcoin. Relative volume solves this by normalizing volume against its own historical average, typically using a 10–20 day lookback period matched to the same time of day.
RVOL readings are interpreted as multipliers: 1.0 is average, 2.0+ is notably elevated, and 0.5 is below average. Day traders and swing traders use RVOL to filter for high-activity setups. A breakout with RVOL of 3.0 carries far more conviction than one with RVOL of 0.8.
According to research by Investors Underground (2021), stocks with RVOL above 2.0 at the time of a breakout showed an average post-breakout follow-through of 4.7% within 3 trading sessions, compared to 1.2% for breakouts with RVOL below 1.0 — a nearly 4x difference in performance. Similar patterns are observed in crypto, where unusual volume on altcoins frequently precedes major price moves driven by whale accumulation or news events.
In crypto, RVOL is particularly useful for identifying which altcoins are seeing unusual interest on a given day. Scanning for coins with RVOL above 2.0–3.0 helps traders focus on the most active opportunities rather than watching dozens of low-activity charts.

Frequently Asked Questions
What is a good relative volume for day trading?
Most day traders look for RVOL of at least 1.5–2.0, indicating 50–100% above-average volume. RVOL above 3.0 signals exceptional activity and the highest-probability setups. Below 1.0, the asset is quieter than usual and is generally avoided for active trading strategies.
How is relative volume calculated?
RVOL = current period volume / average volume for the same period over the lookback window. For intraday RVOL, the calculation matches the time of day to account for natural volume patterns (e.g., higher volume at market open). Typical lookback periods are 10–20 days.

Volume Analysis
Volume analysis studies the number of units traded during a given period to confirm price moves, identify trend strength, and spot potential reversals. High volume validates breakouts and trend continuation, while declining volume during a move warns of weakening momentum and potential exhaustion.
Volume Profile
Volume Profile displays trading volume distributed across price levels over a specified time period, showing where the most and least trading activity has occurred. High-volume nodes act as strong support/resistance; low-volume nodes (gaps) act as areas where price moves quickly.
Breakout Trading
Breakout trading is a strategy that enters positions when price moves decisively above resistance or below support, typically accompanied by increased volume. The breakout signals the start of a new trend or the continuation of an existing one as supply or demand overwhelms the opposing side.
