Subject: Re: GTR1 Question: Volume
Thanks for the codes. Interestingly, minus(adv(1,1),adv(2,1) matches the Yahoo provided volume for Jan 23 and earlier. For Jan 24, I checked a few symbols and the GTR value is less than the Yahoo values. I guess there is some variation after the close and the results end up merging with 24 hours.

As a follow-up, GTR1 and Yahoo now agree on volume for 1/24. The number in GTR1 changed to match the Yahoo number I saw yesterday.
