Hey Michael,
Thanks for sharing your ideas!
All seems good to me, and here are a few tips:
2. You don;t need to import data to EA Studio – it’s data is briliant, just make it work for your broker by changing the symbol settings.
9. You don’t really need to do it for all timeframes. You will see that there are a few that works best.
Also, at the end you can recalcualte the EAs without using the last one month of data. So do all of than without the last month (you can check it from Data Horizon) and then uncheck it which will be a good forward testing.
Cheers,
