With a 'kind of' open source bent, but not really, but have some merit for latent information, some tabs I've had open in my browser:
- Open Source Hedge Fund with some tools and data sources and strategies for trading, but it does have a page for Getting Started: Building a Fully Automated Trading System.
- Sentosa – An Open Source High Frequency Automatic Algorithmic Trading System and Research Platform but the site and the code don't seem to be receiving much maintenance, but does have a repository of strategy ideas.
- Zorro Trading - a basic technical analysis based trading engine, but has some ideas to which I aspire.
With a plug to my own code in progress: Trade Frame.
