This is what separates basic plugins from "top" ones.
To compile a top-tier AmiBroker data plugin source code, you need:
Note: Many plugins fail because they link dynamically to the CRT. A top plugin static-links everything.
// Real-time WebSocket thread DWORD WINAPI WebSocketThread(LPVOID lpParam) struct lws_context_creation_info info; memset(&info, 0, sizeof(info)); info.port = CONTEXT_PORT_NO_LISTEN; info.protocols = protocols;struct lws_context *context = lws_create_context(&info); while(!g_shutdown) lws_service(context, 50); // 50ms timeout // Parse incoming JSON tick if(new_tick_arrived) QuoteEx q; q.dDateTime = current_time; q.dOpen = json_tick["price"]; q.dHigh = json_tick["price"]; q.dLow = json_tick["price"]; q.dClose = json_tick["price"]; q.ulVolume = json_tick["volume"]; // Push to AmiBroker via callback g_pDataSite->AddRealTimeQuote(&q);
Why this represents "top" source: It uses asynchronous lws_service, not blocking recv(). This ensures AmiBroker can request data simultaneously while the plugin ingests ticks.
The entry point is a C/C++ DLL that exports specific functions AmiBroker calls during initialization. Here is the canonical structure of a high-performance plugin:
// Top-tier plugin structure #include "ABPlugin.h" // AmiBroker SDK Headers// Global handles for thread safety HANDLE g_hStopEvent; CRITICAL_SECTION g_csDataQueue;
// Required Export: GetPluginInfo ABAPI void __stdcall GetPluginInfo(PluginInfo *pInfo) pInfo->ulSize = sizeof(PluginInfo); pInfo->ulVersion = AB_PLUGIN_VERSION; pInfo->ulPluginType = PLUGIN_TYPE_DATA; strcpy(pInfo->szPluginName, "My Top Data Source");
// Required Export: CreateDataPlugin ABAPI IDataPlugin* __stdcall CreateDataPlugin() return new MyCustomDataPlugin();
Why this is "top" quality: Notice the CRITICAL_SECTION. Top developers ensure thread safety because AmiBroker calls the plugin from multiple threads (UI refresh, backfill, real-time tick gathering). amibroker data plugin source code top
For quantitative traders and system developers, AmiBroker stands as a colossus of performance and flexibility. However, its true power is unlocked only when you connect it to a proprietary or specialized data feed. This is where the AmiBroker Data Plugin becomes the most critical piece of infrastructure in your trading stack.
If you have found yourself searching for the phrase "AmiBroker data plugin source code top", you are likely not just looking for a pre-compiled DLL. You want the blueprint. You want the architecture, the best-in-class coding patterns, and the open-source gold standards that allow you to build, modify, or audit a plugin that streams real-time ticks or historical EOD data into AmiBroker with sub-millisecond efficiency.
This article is a 3,000-word technical deep dive into the ecosystem of AmiBroker plugin development. We will explore the top-tier source code structures, the non-negotiable API contracts, memory management secrets, and the leading open-source repositories that serve as the foundation for professional-grade data plugins.
If you are serious about "amibroker data plugin source code top", you have three pathways:
Final word from a 10-year veteran: The top source code isn't the one with the most features; it's the one that handles disconnections gracefully, uses zero polling, and survives a 10,000-tick-per-second stress test. Reverse-engineer the open-source examples, master the CRITICAL_SECTION, and you will build a plugin that rivals commercial offerings.

Amibroker is a popular technical analysis and trading platform, and its data plugin architecture allows developers to create custom plugins to fetch and manage data from various sources.
Here's a useful paper covering the Amibroker data plugin source code:
Amibroker Data Plugin Development Guide
Introduction
Amibroker provides a powerful data plugin architecture that allows developers to create custom plugins to fetch and manage data from various sources. This guide provides an overview of the Amibroker data plugin development process, including the plugin architecture, data structures, and API.
Plugin Architecture
An Amibroker data plugin consists of a DLL (Dynamic Link Library) file that exports a set of functions. These functions are used by Amibroker to interact with the plugin and retrieve data. The plugin architecture is based on the following components:
Data Structures
Amibroker uses a set of data structures to represent financial data, including:
API
The Amibroker data plugin API provides a set of functions that must be implemented by the plugin developer. These functions include:
Example 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:
#include <Amibroker/Plugin.h>
// Define the plugin interface
extern "C"
__declspec(dllexport) int GetBar( const char *symbol, int period, int index, Bar *bar )
// Read data from CSV file
FILE *file = fopen("data.csv", "r");
if (file == NULL) return 0;
// Find the symbol and period
char line[1024];
while (fgets(line, 1024, file))
if (strstr(line, symbol) != NULL && strstr(line, period) != NULL)
// Parse the bar data
sscanf(line, "%d,%f,%f,%f,%f,%f", &bar->time, &bar->open, &bar->high, &bar->low, &bar->close, &bar->volume);
fclose(file);
return 1;
fclose(file);
return 0;
__declspec(dllexport) int GetQuote( const char *symbol, Quote *quote )
// Not implemented
return 0;
__declspec(dllexport) int GetSymbolInfo( const char *symbol, SymbolInfo *info )
// Not implemented
return 0;
__declspec(dllexport) int GetTicker( int index, char *ticker )
// Not implemented
return 0;
This example plugin provides a basic implementation of the GetBar function, which reads data from a CSV file.
Conclusion
Developing an Amibroker data plugin requires a good understanding of the plugin architecture, data structures, and API. This guide provides a useful overview of the development process, and the example plugin source code demonstrates a simple data plugin that reads data from a CSV file. With this information, you can create your own custom data plugins to fetch and manage data from various sources.
Creating an AmiBroker data plugin requires using the AmiBroker Development Kit (ADK)
, which provides the necessary C/C++ headers and sample source code to interface with the AmiBroker core engine.
Below is a structured "paper" or guide on setting up and coding a data plugin from scratch. 1. Getting Started: The AmiBroker Development Kit (ADK)
The ADK is the official package for C/C++ developers to build custom indicator or data plugin DLLs. Get the latest ADK from the AmiBroker Download Page Essential Files: The kit includes
, which contains the required data structures and function prototypes for the plugin interface. about.gitlab.com 2. Development Environment Setup You can use standard C++ environments like Visual Studio or even the free about.gitlab.com Project Type: Create a new Win32 Dynamic-Link Library (DLL) Configuration: Set the project to build a to your project's include path. Ensure the calling convention is for exported functions. about.gitlab.com 3. Key Functions to Implement
A data plugin must export specific functions that AmiBroker calls to retrieve quotes and configuration details. GetPluginInfo
Returns the plugin's name, version, and type (Data/Indicator).
The core function that provides price data (OHLCV) to AmiBroker when requested. SetTimeFrame Notifies the plugin of the current chart's time interval.
Handles events like database opening, closing, or workspace changes.
(Optional) Opens a dialog for user-specific settings like API keys or server addresses. 4. Basic Source Code Structure The most efficient way to start is using the Data_Template provided in the ADK archive. about.gitlab.com // Sample skeleton for GetPluginInfo GetPluginInfo( PluginInfo *pInfo ) { pInfo->nStructSize = PluginInfo ); pInfo->nType = // 1 for Data Plugin pInfo->nVersion = // version 1.0.0 strcpy( pInfo->szID, "MY_DATA_SOURCE" ); strcpy( pInfo->szName, "My Custom Data Feed" Use code with caution.
