Handles events like database opening, closing, or workspace changes.
Give the database a name, click , and locate your Top Custom Data Plugin inside the "Data Source" dropdown selection menu.
To help tailor a concrete template for your needs, could you share a few details?
AmiBroker interacts exclusively with this thread. It must never block, or the charting UI will freeze.
#include <Amibroker/Plugin.h>
A background thread initialized inside the plugin's Notify function. This thread runs an event loop connecting to your data socket (e.g., via libwebsockets or cpprestsdk ).
If you are searching for "top" source code examples, look for these architectural patterns:
Building a custom data plugin utilizing AmiBroker's C/C++ Development Kit (ADK) allows for seamless integration of external data streams directly into the database engine. 1. Architecture of AmiBroker Data Plugins

AmiBroker data plugins are specialized that bridge the software with external data sources like real-time brokers, proprietary databases, or web services. Core Architecture of a Data Plugin
I can then give you more specific code examples or a tailored architectural plan. Amibroker Plugin - What is OpenAlgo? | Documentation
For algorithmic traders and quantitative developers, AmiBroker remains one of the most powerful technical analysis platforms available. However, its true potential is unlocked not just by its formula language (AFL), but by its ability to connect to virtually any data source.
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. Handles events like database opening, closing, or workspace
Here's a useful paper covering the Amibroker data plugin source code:
Here's an example plugin source code in C++ that demonstrates a simple data plugin that reads data from a CSV file:
Backfilling is another essential feature. When a user opens a new symbol, the plugin must recognize that historical data is missing and trigger a request to the data provider's server. This is typically handled through a background thread to ensure that the AmiBroker user interface remains responsive while the historical bars are being downloaded and processed. Performance and Stability Considerations
Automated retrieval of historical data.
