QDMS is a client/server system for acquiring, storing, managing, and distributing low-frequency historical and real-time data, written in C#.

The server acts as a broker between clients and external data sources, as well as a local database of historical data. The server GUI allows its use without the need for a client application.

• Server Installer

A client library is provided which can access the server either locally or over a network, to request data/metadata, schedule jobs, etc. A sample application showing usage of the client can be found here. Get the client library on NuGet:

For bug reports, feature requests, etc. use either the GitHub issue tracker or gitter chat.

• Manage metadata on stocks, options, futures, CFDs, cryptocurrencies, etc.
• Stream real time OHLC & tick data to your applications.
• Download historical and real time data from external data sources and store it locally.
• Download and store earnings announcements, dividends, economic releases.
• Generate continuous futures data.
• Schedule automatic data updates.

Adding more sources is easy and contributions are welcome.

• MySQL/MariaDB or SQL Server (2008+)
• .NET 4.8 (.NET Core support planned)
