I want to use my quantitative finance programs for real world trades on financial spreads; forex, indices, stocks etc. The features presented by many providers are for the human interaction side. There is usually very little information evident for how to connect and automated system to their service. Which providers are examples which allow good application interface? What are indicators that a service is geared towards users through their program logic?
