On PRT trading, market data for Valeo on March 8th for the 4h 3 candles is respectively: 595096, 463663 and 858287, total 1917046, matching daily TF data. So… not a platform issue when using market data.
Looks like you are using IG cfd data. It doesn’t explain the difference « daily vs intraday sums » (other intraday TF add up to 4197 too like 4h) whatever that data is, but that would be more a question for them (IG, as your broker), unless a user here already asked them and steps up to help with their answer.
