Hydra

Hydra automatically downloads market data from different sources and stores it locally. It supports instruments, candles, tick trades, order books, and other data types. Data can be stored in the special Hydra binary format (BIN), which provides high compression, or in CSV format for analysis in other programs.

Stored data can later be used by trading strategies. For strategy testing, see Backtesting. Data can be accessed directly through StorageRegistry (see Market-data storage) or exported to formats such as Excel, XML, or TXT (see Installation and operation).

Hydra can work with both historical and real-time data sources, for example OpenECry or Rithmic for order books. The plugin model also lets you create custom data sources. For details, see Creating source.
