50x Faster Bitcoin Price Data Powered by MarketStore for AI Trading
Blog post from Alpaca
MarketStore is an open-source financial timeseries database used for storing and querying historical price data. The current setup uses a background worker to fetch minute-level historical prices, which provides faster data speed compared to the previous setup that fetched daily bar data. This increased data speed enables more backtesting and training in machine learning for trading algorithms. MarketStore offers scalability advantages over PostgreSQL, allowing it to serve multiple symbols and timeframes efficiently. It also reduces the need for complex queries, making it easier to query larger datasets. The performance benefits of using MarketStore were demonstrated through benchmarking tests comparing its speed with PostgreSQL.
