Hi all, I am looking for the best open source auto-trading platform, based upon which I could build my auto trading system. Hopefully it is mature. It can link to InteractiveBrokers and has lots of users to discuss with, and has order management facilities. And it also has the capability to do both backtesting, papertrading, and real-trading. Moreover, hopefully it has lots of indicators, much like TradeStation. Please give me some pointers! Thank you! ----- Maybe I should drop the requirement of "lots of technical indicators", because for that maybe TradeStation is better anyway... so the workflow will always be to use TradeStation to do historical back-test and then use ATS+IB to do real trades... Any thoughts?
