Wow, I used to use EAs on Forex.com all the time with demos for testing years ago, sad to hear they are banning that now. Didn’t someone say they were offering MT5 accounts for US citizens now? Last I heard they still had no plans to do so, but I haven’t confirmed that recently. Trading.com is probably the best broker for US clients, the others are pathetic brokers.
