Hello, I am comparing GOOGL's daily data (open high low close volume) from Sierra to that of NASDAQ. Small differences between the prices were observed. While the differences between volume numbers cannot be regarded as small and are quite consistent. For example, according NASDAQ the trading volume on GOOGL on 21st Aug 2015 is 4,525,625 compared to 3,958,595 provided by Sierra. This is the NASDAQ page for GOOGL data: https://www.nasdaq.com/symbol/googl/historical Please help with understanding the differences.
