Take advantage of SQLite's capabilities for intermediate data storage, analytics, and integrations of the MetaTrader platform. Keep all your data in one place.
Use the saved data in SQL analytical queries, from Python and other languages, to build dashboards
Parameters
- useDefaults true - use default parameters. Save data to the COMMON hierarchy, to the db/ram/{server_name} directory.{account number}.trade.db
