At Alpaca, we truly believe open source and the community around it can change financial systems and how we interact with them. It is our commitment to contribute to the community as much as possible. With that in mind, we set up a few initiatives where you can learn from and contribute to the community.

As you get deeper into trading and automation, there are many questions and hurdles that you may face while trying things out. We find that our community has been growing rapidly to share what they do with each other. Alpaca grows with our community and knowledge is built together.
