I'm a retail algorithmic trader. I've written some algorithms that parse intraday movements and make decisions. I still execute trades manually but eventually I need the ability to execute trades on the fly.
I need a platform where I can implement these algos in C#, F#, Java or Python against live data feeds to flag the situations.
Obviously, TD Ameritrade has Thinkscript but it's not really what I need. I need to be able to use regular programming languages against live data.
