Hello,
unfortunately, all brokers do not provide a lot of data from the beginning.
The data that is in EA Studio comes from JFD which is not a bad broker. Also, from Forex Software they developed an app for Historical data that comes from Ducascopy and it is very good data.
Still, I will need to test it before we place it on our website, so everyone can download it for free.
If you want to use any other broker, you will just need to collect the data.
Cheers,
