pre-market volume indicator report: what it measures and how traders use it

the pre-market volume indicator report on edgeful measures the relationship between pre-market volume (4:00 AM-9:15 AM ET) and regular session volume (9:30 AM-3:45 PM ET).
calculates a correlation coefficient so you can see whether higher or lower pre-market participation reliably predicts a more or less active regular session.
this is one of the 150+ reports available on the edgeful platform. here's how it works, what the data shows, and how traders use it.

what the pre-market volume indicator report measures
splits each trading day into a pre-market window (4:00 AM-9:15 AM ET) and a regular session window (9:30 AM-3:45 PM ET), sums total volume for each window, and reports both the mean volume per window and the correlation between the two daily series.
the report is available for futures, stocks, ETFs, forex, and crypto. you can filter by ticker and lookback period.
how the calculation works
the pre-market volume indicator report compares the total volume of two time windows per day.
- the report filters historical data into pre-market (4:00 AM-9:15 AM ET) and regular session (9:30 AM-3:45 PM ET) subsets
- it groups each subset by trading day and sums total volume
- both volume series are averaged across the lookback to produce mean pre-market volume and mean regular session volume
- a Pearson correlation coefficient is calculated between the two daily volume series
- the higher the correlation, the more reliably pre-market volume predicts regular session volume
how traders use pre-market volume indicator data
- gauging whether to expect an active or quiet regular session before the bell
- sizing up when pre-market volume is significantly above average and the ticker correlates
- sizing down or stepping aside when pre-market volume is significantly below average
- pairing with pre-market range correlation for a full volume + range pre-session read
- adapting your aggression to the day's expected participation instead of trading every open the same way
the data doesn't tell you to trade. the pre-market volume indicator report tells you the historical performance of the setup in front of you. what you do with that information is your decision.
results require customization, time, and effort. the numbers change depending on your ticker, session, and lookback period. always check the data for your specific conditions.
