: Look at DataSource.cs in the repository for an example of how to implement GetQuotes() to return price data to AmiBroker. amibroker data plugin source code top
AmiBroker requires a C-interface DLL. While you can use "wrappers" for C# or Python, they often introduce latency. For high-frequency data, C++ is the industry standard. For high-frequency data, C++ is the industry standard

Because AmiBroker is a 32-bit or 64-bit multi-threaded application, thread safety is paramount. Developers must use mutexes or critical sections when accessing shared data structures to prevent crashes. Furthermore, memory management must be impeccable; leaking memory in a data plugin will eventually lead to system instability, especially during long trading sessions where millions of ticks may be processed.
