I just started live trading 6 months ago after about 10 years of demo/learning how to trade Forex. I currently have Two accounts one: 100K account and another 50K account. I am curious about finding a broker preferable a ECN broker that can handle massive standard lot sizes around 100 lots-10,000 lots if possibly. I plan on depositing at least 5 Million to start. Does anyone know a reputable broker?
