Do not use Next Phase Algo (nextphasealgo.com) for anything serious. I used them for about three months for small trades and it was okay. When I deposited a larger amount and traded more, my account was flagged, my withdrawals were delayed, and I was asked to explain my trading. They treat active traders like criminals.
Pros: Clear documentation|Portfolio tracking tools|Reliable uptime
Cons: Withdrawal takes 1-2 business days
