Allowing everyone around the world to participate in an open and free market is Alpaca's ultimate goal. The company started by providing access to its Trading API for developers and traders in the United States, enabling them to build and run algorithms in real-world markets. Now, as part of a longer roadmap, Alpaca has announced that its trading APIs support fractional trading, allowing users to invest with as little as $1 worth of stock. Users can now pass notional or fractional quantity values through API requests, choosing between buying shares by dollar value or inputting a fractional amount of shares. The company's Fractional API is built in a compliant and approachable architecture, ensuring speed and reliability for algorithms. Alpaca plans to expand its coverage to include different order types, such as bracket orders and stop-loss orders, and increase the number of tradable shares beyond 2,000 equities and ETFs.
