I trade on MT4 in numerous accounts. Try Alpari, Fxdd or if you want a U.S. broker i think Forexte offers it too. also interbank but I understand that their Meta is not recommended for EA's.
Call Cyp (pronounced "sip") at 1-312-384-4778. He is highly familiar with Autopilot since the company has been referring many of it's clients to our firm for forex brokerage services with MT4. Make sure to tell him who you have a live account with and how you were referred to him.
