Hi everyone. Ran into an issue for my backtesting.

Requested 2025-26 tick data from my broker of 5.9GB of tick data and algo working well.

Prev year of 2024-25 is 2.4GB and has 3x less tick density than the other.

Again half the tick density for the prev year of 23-24.

My question is shall I be trusting this data from previous years prior to 2025 or will the data be fairly accurate?

My EA relies heavily on tick data to engage trade but if the density is reduced this much is it worth even trusting?

Thanks all
