It sounds like you are looking for to include in an Amibroker data plugin (real-time or historical feed), specifically if you are writing or evaluating source code for one.
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.
When dealing with high-frequency data, small memory leaks or inefficiencies can crash AmiBroker during long trading sessions. Avoid Memory Allocations in the Main Loop

AmiBroker data plugins are standard Windows Dynamic Link Libraries (DLLs) that implement a specific set of exported functions defined by the AmiBroker Development Kit (ADK). The plugin acts as a bridge, translating your data source’s format into AmiBroker’s internal structures. The Two Data Models AmiBroker plugins can operate in two primary modes:
Give the database a name, click , and locate your Top Custom Data Plugin inside the "Data Source" dropdown selection menu.
The search for is not about finding a single file to copy-paste. It is about understanding the contract between your data source and Amibroker’s high-performance database engine. It sounds like you are looking for to
Open Microsoft Visual Studio and create a standard C++ Win32 Dynamic-Link Library (DLL) project.
Developing a custom data plugin for AmiBroker allows you to stream real-time or historical market data from any source directly into the software's high-speed database. This is typically achieved using the , which provides the necessary C/C++ headers and architectural guidelines. 1. Core Architecture and ADK
// Fetch logic here... *pResult = QUOTES_OK; return 0; When the software needs to update a chart,
#pragma pack(push, 1) struct Quotation __int64 DateTime; // Packed date/time format float Price; // Close price (or Last price) float Open; float High; float Low; float Volume; float OpenInterest; ; #pragma pack(pop) Use code with caution. Key Considerations for Data Fields
Several developers have published their custom data plugins on GitHub, which act as excellent, modern examples of how to connect to web sockets or REST APIs.
