I have been running Petko’s 12 EA system, which has been working quite well.
ROI: 7.12%
Max Draw Down: 5.3%
I found that running Petko’s 12 EA was not the best because they were not trained on my broker’s data (Forex.com).
So I run EA Studio Night and Day on all 6 symbols on 4H 1H and 15M. And then I pick the top 2 for each symbol.
Also, a little tip for US traders the way I get around the FIFO rule is to have 2 broker accounts and run 6 EA in each.
The point is not to run the same symbol twice in one account.
