Rolling Average Daily Trading Volume (ADTV) is a dynamic measure of an asset’s trading activity over a specified period, updated continuously as new data becomes available. Unlike a fixed average, which is calculated once for a set timeframe, rolling ADTV recalculates the average each day by adding the latest trading volume and removing the oldest data point within the chosen window, such as 10, 20, or 30 days.

This approach provides a more current and responsive view of market activity. For example, a 30-day rolling ADTV reflects the average volume traded over the most recent 30 days, adjusting daily to capture shifts in participation and interest. As a result, it helps traders and analysts identify trends in liquidity more accurately than static measures.

Rolling ADTV is particularly useful for spotting changes in market behaviour. A rising rolling ADTV may indicate increasing investor interest, stronger momentum, or the entry of institutional participants. Conversely, a declining value can suggest weakening demand or reduced engagement with the asset.

Traders often use rolling ADTV to assess liquidity, manage risk, and validate trading signals. Higher rolling volumes typically mean tighter spreads and easier order execution, while lower volumes can lead to slippage and price instability.

Overall, rolling ADTV is a practical tool that offers a real-time perspective on trading activity, enabling more informed and timely decision-making.
