Hack Financial Systems have seen significant growth since launching the Alpaca Trading API nine months ago, supporting a growing number of individuals and businesses in building applications and trading strategies. The introduction of new features through the Web API v2, including commission-free short selling, margin trading with a competitive interest rate, pre-market and after-hours trading, and business account onboarding, aims to empower traders and further enable them to "hack financial systems". Alpaca is committed to building a software infrastructure that enables seamless interaction with the financial market, and encourages developers to join their community and contribute to open source projects.
