There are 3 differences, none of them is truly technical since they are working on the same pairs and the same EA.
The differences are:
1. OM Flex 2 is simply newer so it doesn't have the vast history track that this one has.
2. OM Flex 2 has another EA, a very solid one, which is attached to it and makes roughly another 0.68% per month
3. On this account, I withdrew at some point 75% of my funds while there where open trades, so the DD became very large at this point. This discourages some people I wanted to show an account without major deposits or withdrawals so it will not affect DD so much.
