Possible disadvantages of Alpaca Data API

  • Limited Asset Coverage
    While Alpaca offers substantial data for U.S. securities, its coverage outside the United States is limited, which may not be suitable for traders interested in global markets.
  • Rate Limits on API Calls
    The free and lower-tier subscriptions have rate limits on API calls, which can be restrictive for users requiring extensive data access or high-frequency data requests.
  • Potential Delays in Real-Time Data
    Depending on the subscription tier, there might be delays in receiving real-time data, which can be a disadvantage for high-frequency traders who rely on minimal latency.
  • Complex Pricing Structure
    The pricing model for accessing different levels of data and other features via the API can be complex, making it difficult for users to estimate costs effectively without a thorough understanding.
  • Dependency on Internet Connectivity
    As with any online API service, the reliability and performance of Alpaca's data feed depend on the user's Internet connectivity, which could be a concern in areas with unstable connections.

Possible disadvantages of Alpaca Trading API

  • Limited Asset Classes
    Alpaca primarily focuses on U.S. equities and ETFs, limiting the variety of assets available for trading compared to other platforms offering forex, futures, options, or cryptocurrencies.
