Over the years I've amassed a large collection of links, resources, tools and so on that I find useful in my trading/investing activities. I'm compiling those here, along with any that were shared with me via Twitter/Reddit/email/etc and seemed useful after a cursory look. While I've done my best to link to tools that are not only legitimate but also likely to stay active, alive and useful for the foreseeable future, obviously I have no control over these companies/websites and over time some of the links may break or situations may emerge that turn them into poor recommendations. Also, this list is not exhaustive by any means and may be updated in the future as new tools/resources emerge.
