If you love using my open-source work (e.g. quantmod, TTR, xts, IBrokers, microbenchmark, etc.), you can give back by sponsoring me on GitHub. I truly appreciate anything you’re willing and able to give!

I look forward to your questions and feedback! If you have a question, please ask on Stack Overflow and use the [r] and [quantmod] tags. Or you can send an email to the R-SIG-Finance mailing list (you must subscribe to post). Open an issue on GitHub if you find a bug or want to request a feature. Please read the contributing guide first! It will help save time for both of us. 😉
