: The primary function for data retrieval. It handles the actual request for price bars (OHLCV) and allows for 64-bit date/time stamps and floating-point volume.
Compile the binary for your specific AmiBroker target environment (compile x86 for 32-bit versions, x64 for 64-bit installations).
The most fundamental part of the source code manages the connection logic. This involves the GetPluginInfo and Init functions. In the source code, this section defines the plugin’s unique ID, the supported data types (e.g., EOD, Intraday, Tick), and the status of the connection. Robust source code in this layer includes error handling to manage disconnections, ensuring that the plugin can auto-reconnect to the data vendor’s server without crashing the Amibroker application.
: The modern function for fetching historical and real-time data. It receives a ticker name and periodicity and must fill a buffer with price arrays (Open, High, Low, Close, Volume, etc.). GetPluginConfig amibroker data plugin source code top
class MyCustomDataPlugin : public IDataPlugin
Test your plugin by:
Tools such as provide wrappers that allow you to write the business logic in C# while the wrapper handles the native function calls required by AmiBroker. 5. Best Practices for High-Performance Plugins : The primary function for data retrieval
Uses a loop to populate the Quotations array. Efficiency here depends on how you handle memory allocation—pre-allocating the array size based on the expected date range is a common optimization.
Handles events like database opening, closing, or workspace changes.
Establishes a persistent socket or API connection to push tick-by-tick updates into AmiBroker's internal workspace. The most fundamental part of the source code
Implement a robust logging system that writes to the AmiBroker "Log" window using SiteContext->LogMessage() . This makes debugging connection drops much easier.
