To understand the source code, one must first understand the interface. Amibroker does not simply read raw text files; it utilizes a plugin architecture based on a standardized interface definition (often utilizing C++). This allows third-party developers to create Dynamic Link Libraries (DLLs) that act as a bridge between a data vendor’s API and the Amibroker charting engine.
The AmiBroker plugin ecosystem is not static. Newer versions of AmiBroker (like 7.00.x) have shown changes in how plugins are loaded, sometimes affecting compatibility with older ones, which underscores the need to stay current with community developments.
Download this from the official AmiBroker website. It contains necessary headers like Plugin.h .
The main workhorse for a data plugin is GetQuotesEx . It is called by AmiBroker whenever it needs quotes for a particular symbol and date range.
AmiBroker is a highly optimized technical analysis and charting platform. Its speed and efficiency stem from its ability to process massive arrays of financial data in native memory. While AmiBroker provides built-in support for many standard data vendors, institutional traders, crypto enthusiasts, and proprietary trading desks often require integration with custom data sources. amibroker data plugin source code top
This is the engine room of the plugin. The source code here defines how Amibroker requests historical or real-time data. It typically involves mapping Amibroker’s internal request structures (asking for a specific symbol, timeframe, or date range) to the external data vendor’s API queries. Efficient source code in this section utilizes asynchronous programming techniques. Since network requests can be slow, "top-tier" source code avoids blocking the main Amibroker thread, ensuring the user interface remains responsive while data loads in the background.
Copy the compiled .dll file directly into the Plugins subfolder inside your AmiBroker installation directory (typically C:\Program Files\AmiBroker\Plugins\ ).
Creating an AmiBroker data plugin requires using the AmiBroker Development Kit (ADK)
This is a more specialized plugin designed to fetch data from the QUIK terminal, which is widely used to trade on Russian markets. The strength of Q2Ami is its modular design; its code is structured to allow on-the-fly conversion of trade streams into any required format. This plugin architecture demonstrates how to build a flexible data processing pipeline. To understand the source code, one must first
// Example Snippet PLUGINAPI int GetPluginInfo(struct PluginInfo *pInfo) pInfo->Type = PLUGTYPE_DATA; pInfo->Version = 100; pInfo->Name = "CustomDataFeed"; pInfo->Description = "Connects to Custom API"; return 1; Use code with caution. 2. Init / Shutdown
For developers looking to use C# instead of C++, the kriasoft/amibroker GitHub repository provides an excellent framework for creating plugins using the .NET framework. It handles the difficult interop communication between the .NET CLR and the native C++ API of AmiBroker. C. Yahoo.com EOD Data Plugin (Example)
This article explores the best resources, top source code examples, and the foundational knowledge required to develop high-performance AmiBroker data plugins. 1. What is an AmiBroker Data Plugin?
All plugin types, regardless of the specific type, share a common foundation: three core export functions ( GetPluginInfo , Init , Release ) and a unique 4‑character ID (obtained from AmiBroker support) that prevents conflicts with other plugins. The AmiBroker plugin ecosystem is not static
: Broadcasts application events like database loading, unloading, or configuration metric updates.
The official way to build a plugin is using the ADK, which includes the C++ API definitions and working examples for both indicator and data DLLs.
The Amibroker data plugin source code provides several key functions that developers can use to create custom data plugins:
The ADK is essential because it contains the skeleton code for native plugins. It serves as the bedrock for all C++ based development. As noted in the official community forums, the ADK specifically includes the source code for sample data plugins such as the and QP2 plugins. AmiBroker staff have explicitly confirmed that studying these examples "is sufficient as an example of how to write data plugins". This makes the ADK the absolute starting point for understanding the core API, implementing essential functions like GetQuotesEx , and compiling the plugin into a functional .dll .
For many, C++ is complex. Using C# via P/Invoke (Platform Invoke) allows for faster development, especially when dealing with modern REST or WebSocket APIs.
