Copy the .dll file directly into your AmiBroker installation subfolder named Plugins (usually found at C:\Program Files\AmiBroker\Plugins ). Launch AmiBroker. Navigate to .
Developing a data plugin is a systematic process. This section provides a high-level guide for developers starting from scratch, covering the initial setup, core functions, and decisions you'll need to make to get your plugin up and running.

While the official AmiBroker Development Kit (ADK) gives you the blueprint, this guide will take you further, exploring the entire ecosystem of available source code. We'll look at the top open-source examples, evaluate the different development pathways—from traditional C++ to modern .NET approaches—and equip you with the best practices needed to build robust, high-performance plugins.

Or, for high-frequency scenarios:
The true complexity of a data plugin lies in how it handles the GetQuotes and GetExtraData functions. AmiBroker operates on a "pull" or "notification" basis. When the software needs to update a chart, it calls the plugin to see if new data is available. A robust plugin must implement an efficient buffering system. Since market data often arrives in bursts, the plugin should store incoming ticks in a thread-safe queue and then flush them to AmiBroker's memory structures during the update cycle.
Use C++ (Community Edition works fine).
This source code focuses on the Import functionality rather than the streaming GetQuotes functionality.
