A storage engine for cryptocurrency market data. You supply the exchanges, data type (trade, book, etc), and trading pairs you're interested in and Cryptostore does the rest!

Stores data to:

• Parquet
• Arctic
• Google Cloud Storage
• Amazon S3

Once installed with pip, an executable is placed on the path, so you can simply run cryptostore to start the collector. It requires a config.yaml file. If its not in the current working directory, you can specify the path to the config with the --config option.

An example config, with documentation inline is provided in the root of the repository. The config file is monitored by cryptostore, so you can change the options in the file and it will apply them without the need to reload the service (this is experimental. If you encounter issues with it, please raise an issue).

• Missing data detection and correction (for exchanges that support historical data, typically only trade data)
• Support other caching engines. Currently uses Redis Streams. Will also support kafka (and maybe others) in near future
• Storing data to InfluxDB
• Storing data to MongoDB
• Subscribing to Book Deltas
• Support for enabling computation and storage of diverse metrics in parallel with data collection (eg. configurable OHLCV)
• Support for forwarding data to another service/sink (eg. to a trading engine).
