Alpaca Trading: API for algorithmic trading

Alpaca Trading positions itself as a platform for algorithmic trading, commission-free stock and ETF trading and robust charting tools through its web-based platform. While Alpaca offers a unique experience for users looking to dive into APIs and programming, its reliability deserves a closer look. Let's examine the platform with a pinch of salt.


  • Commission-free trading: Alpaca allows users to trade stocks and ETFs without commissions, making it attractive to newcomers.
  • Low margin rates: The platform boasts low margin rates, making it attractive to frugal traders.
  • Convenient account opening: Opening an account with Alpaca is quick and there are no minimum deposit requirements, which helps attract a wide range of investors.
  • API and charting tools: Alpaca provides excellent API tools and charting capabilities, allowing users to efficiently create their own algorithms.


  • Limited customer support: Alpaca relies heavily on GitHub, Slack, and other community forums for user support, as its customer support is notably limited.
  • Limited funding methods: Deposits and withdrawals are limited to bank transfers only, excluding more convenient options such as credit/debit card transactions.
  • Limited product selection: Alpaca's product range covers only US stocks, ETFs and cryptocurrencies, excluding other asset classes and international markets.

Trading Experience

Alpaca's web-based platform is secure, user-friendly, and visually appealing. However, it lacks customization options, price alerts, and a limited search function. And the mobile platform is even simpler, but it lacks advanced search and price alert features, making it less versatile.

Educational Resources

Alpaca offers video tutorials, step-by-step guides on investing, algorithmic trading, and API usage, as well as detailed guides and FAQs for beginners.

Regulation and Security

Alpaca Trading operates under the supervision of top-notch US regulators, which ensures strong investor protection. However, the lack of a banking license or public listing may raise doubts about transparency.


In conclusion, Alpaca Trading is an excellent broker for traders interested in developing their algorithms, especially in the US market. Its excellent API tools, low fees (zero stock/ETF commissions and no inactivity or deposit fees), and free access to powerful software such as Polygon, Alpha Vantage and TradingView make it an attractive choice.

However, potential users should be mindful of the platform's limitations, including limited customer support, reliance on bank transfers and a product range limited to US assets.
