Every once in a while a look through my LinkedIn feed unearths a juicy(?) nut.
Thanks to Mr Madan for posting this quite impressive list of open-source trading platforms.
Perhaps a good time for a slight tangent: a few years ago, when I started developing quant strategies, I was pleasantly shocked to find out about open-source software, and particularly how deep these offerings were. It’s frankly AMAZING that, for just about any software developing requirement I’ve ever heard of, there’s a free open-source solution. Hence my love for languages such as Python and R, databases such as MySQL, and tools such as Spyder and Sequel Pro. Oh, and stackoverflow: not only are the tools free, but the tech support is free and generally kind. Oh, and Quandl for free data.
In sum: always look for the open-source alternative if you come across a software need.
