Symbol PPP
3-21 Vol spike on dailly chart says over 18 mil shares
Go to 60 min chart and add up the vol bars, its not even close to that, less than 5 mill
Which is right,? why the discrepency? This is a big deal to me. I have a strategy /sort in part based on daily volume . If the daily volume is wrong, or unreliable, my system is unreliable.
Does this discrepency occur on a regular basis?
Thanks.

The daily volume for PPP on 3/21 is being reported everywhere as 18 million shares. I agree that summing up the intraday volume (hourly) doesn't add up, but I'm finding the exact same thing from other sources. Right now, I can't account for the discrepancy.

It COULD be that the Day total includes trades not made during trading hours, and/or trades made by what Martha Stokes refers to as Dark Pools. These would not show in hourly totals during trading hours.
Note the Caps on "could". Its a suggestion, not a defintitve answer
