missing tick data

 

Yesterday when I was doing some backtesting of EA

I realised that ticks data were missing for year 2023 and before resulting the testing quality to be 0

What could have happened?

Do I need to contact the broker for this?

I have tried to delete all tick data and tried to re-download but data are still missing for 2023 and before
