I tried OEC long time ago, and I was not that impressed and went for another solution. I think it is not completly bad, there are just much better alternatives available.
Even Rick Tomsic, founder of OEC, moved on and launched Tradovate in 2015, which I like MUCH more, especially their pricing (only place I know where a small retail trader can trade the Bund for less than 0.50 EUR per contract, all-in).
@IronFist, where are you moving your account now ?
