I’m trying to gather pre-market minute data but I don’t seem to be seeing all of the data. My calculations of AAPL on 7/24 was 10192. Is this volume data given in getBars supposed to be multiplied by something? Also, is there any way to initiate data streaming pre-market?

this.alpaca.getBars(‘1Min’ is the type I’m using. I’m using a 2.5 hour spread from 6am-830 Central Time. Its only returning me 29 data points in that span. Any ideas?
