Do you not see a 30% difference for 7/22/22 and a 50% difference for 7/29/22 in the one-minute SPY volume you are providing compared to NYSE on your side? Given that BarChart is your data source for this volume, and BarChart agrees with NYSE, I fail to understand how a new data source will resolve the discrepancy.
