Post From: SC Gives Different 1-Min volume for SPY than NYSE's Website

I'm seeing significantly different volume for the SPY on Sierra Chart than I do on NYSE's website that is affecting my volume based indicators (e.g. VWAP). For example, the one-minute volume on SC for 9:30 EST today (7/19) is 410K. The volume I see on NYSE's website is 665k (https://www.nyse.com/quote/ARCX:SPY), which also agrees with what I see on TradingView. Why is the volume off and how do I get the same volume as NYSE?
