Backtesting Problems

 
Hello, I have been backtesting MT5 for 3 years.
from 2020-01-01 to the present day.

however, on December 29, 2023, the quality of the data dropped. from 99% to 67%.
In several brokers.

I've tried pepperstone, ic market, FTMO, etc...
all of them with low quality on 01-01-2020.

 Quality will be good again in June/01/2021

It appears that data was lost from 01/01/2020 to June/01/2021

Anyone else experiencing this problem?


If you have a good broker to share, with long date quality data, let me know! 
im ea trader and its important!

Most brokers will provide you incomplete tick data, what you can do is buy the data or find a free source, tickstory is an option
