Hi Mathew.
This seems like a big success really. Especially as you were just getting pure losses hen you entered this thread right?
Balance drawdowns are pretty inevitable. Have you been keeping an eye on your equity drawdown?
Also am I right in that you are moving EAs from demo to your mock live account monthly and still working with the same EAs on the original demo?
I would recommend keep doing what you are doing for another month or two but also maybe run a second system side by side using the EXACT same process.
It could be that this is just a natural drawdown and you may get another profitable overall three months OR perhaps the life cycle of your system starts to deteriorate after 2-3 months?
4+ grand profit on a 10k account over three months is a great result as far as I am concerned.
