Before diving into source code, we must understand the hierarchy. Amibroker uses a (Software Development Kit) to interface with external data sources. The "top" plugins (like those for Interactive Brokers, eSignal, or custom WebSocket feeds) share three traits:
While the benefits are substantial, writing this source code is not without challenges. The primary difficulty lies in thread safety. Amibroker is multi-threaded, meaning it can request data for multiple symbols simultaneously. If the source code is not written with thread-safe logic (using mutexes or critical sections), race conditions can occur, leading to corrupted data or software crashes. Therefore, the "top" concern for any developer is ensuring that global variables and connection handles are managed safely across concurrent threads. amibroker data plugin source code top
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.
