What is the best ECN broker for US residents, MT4 and MT5

OK,

Newbie here. I’m sure this question will get me the standard newbie abuse but here goes…

What is the best ECN broker for a US resident who wants to develop EAs in MT4 and MT5.

…preferably a broke that offers a demo account.

Thanks,

S

Brokers I know of are Exness, which is a market maker (I won’t recommend market makers for newbies). Then Profiforex, an STP/NDD broker that allows you to upload any honest EA.
