I was exploring 09988HK dataset. I noticed that the volume and price data are not consistent and vary greatly from the data i have from my broker and also data from tradingview. Can i know the source of equity data in the Algogene platform? i have looked at this post which explains about the inconsistency. But my experience with the data is too weird  for e.g. on  2024-10-16 00:00:00, the volume is only 2777 and on 2024-10-17 00:00:00 the volume is 2604. The actual volume on those days are in millions for 09988HK. Why such big margin of error?
