I have recently started writing and testing automated systems with a partner. We chose to start with interbankfx because they work with MetaQuote's free software, and they also allowed us start out with less risk capital in a mini account. Forex also seemed like the perfect product to trade, having a 24 hour market with very high liquidity around the clock. However; experience has definitely changed our outlook. For starters, the connection reliability of InterbankFX has proven horrible. They claim that it is due to a recent wave of new customers and that it will improve, but until I actually see improvement I'm not confident trading with them. In addition, I've noticed that the trading systems I've tested profitable against equities on wealth-labs site aren't generally profitable in forex. I understand that different markets behave differently and that is normal, but I'd like to be able to trade against multiple markets and further diversify my trading approach rather than throw out those systems. To cut to the chase, I'm looking for recommendations for brokerage and software combinations that would allow us to trade in multiple markets from a single account while keeping our costs as low as possible. I've taken a look at Interactive Brokers, and they offer me the ability to trade the markets I want, but I am unsure of what software would be good for them. We've acquired a copy of amibroker, but the automated trading capabilities seem very limited. They themselves even warn against using their software to trade in a live account. Tradestation offers a very nice software package, but it looks as though you need to have a separate account for each market you want to trade. In addition there is a recurring cost to their software if you do not trade enough, even though typically that shouldn't be an issue with our systems. I'd be interested in any recommendations anyone has in the way of software or brokerages that they have used to utilize automated trading. Thanks in advance.
