RVOL - Relative Volume Intraday

In the context of intraday trading, RVOL stands for Relative Volume. It is a technical indicator that compares the current volume of a stock to its average volume over a specified period. A RVOL above 1 suggests higher than average trading volume, potentially indicating increased interest and volatility. 

The precise definition of real time relative volume is current cumulative volume up to the time of day divided by average cumulative volume up to this time of day. It means for example taking the volume from 09:45 to 10:00 and comparing it to what it does from 09:45 to 10:00 every day.

This indicator supports all timeframes from1 minute to 4 hours.
