Hello Jay-R,
I think you are doing a great job!
I have been trading with Expert Advisors and EA Studio for about two years now (since I met Petko and his courses).
The first six months, I did not pay attention to the Historical data, and it caused me some losses. However, after 1;1 call with Petko I understood the importance.
Now I am collecting from 3 brokers, but I use 2.
One is JFD, and I am using the Metatrader-Demo data from the EA Studio because it updates regularly.
When I compared Demo and Live data for the last time ( about one year back), it was very similar. So I use it from EA Studio.
No, you are not over-doing it. Everyone who is NOT doing it is on the wrong path…
Cheers,
