Code Top !link! - Amibroker Data Plugin Source

AmiBroker data plugins are specialized Dynamic Link Libraries (DLLs) that bridge the software with external data sources like real-time brokers, proprietary databases, or web services. Core Architecture of a Data Plugin

To create a functional data plugin, you must implement specific exported functions defined in the AmiBroker Development Kit (ADK).

GetPluginInfo(): The most critical entry point. AmiBroker scans the Plugins folder and ignores any DLL that does not export this function. It provides metadata like the plugin name, vendor, and version.

GetQuotesEx(): 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.

Notify(): Used by AmiBroker to signal events to the plugin, such as when a database is loaded or unloaded.

GetStatus(): An optional function that reports the connection health (e.g., "Connected", "Trying to connect...") to the AmiBroker UI. Top Source Code Examples

Development typically uses C++ (via the ADK) or .NET (C#/VB.NET). ODBC/SQL Universal Data/AFL plugins - AmiBroker

Building your own AmiBroker data plugin is the ultimate "power move" for traders who want total control over their data feeds—whether you’re pulling from a custom crypto API or a proprietary SQL database.

Here is a blog post draft that dives into the technical essentials, top source code examples, and how to get started.

Unlocking the Engine: A Deep Dive into Amibroker Data Plugin Source Code (Top Examples & Architectures)

By: Quantitative Developer’s Desk

In the world of algorithmic trading, Amibroker remains a gold standard for backtesting and analysis. Its speed is legendary, but its true power lies in its extensibility. While Amibroker comes with built-in data sources (ASCII, MetaStock, Yahoo), the holy grail for institutional and serious retail traders is the Amibroker Data Plugin.

If you have ever searched for “Amibroker Data Plugin Source Code Top” or “how to build a custom 64-bit plugin,” you know the documentation is sparse. This article is your definitive guide to the architecture, open-source references, and coding secrets behind the top-tier data plugins.

The 3 Critical Functions (from plugin.h)

Every plugin must implement:

  1. GetQuotesEx – The workhorse. Amibroker calls this to request historical bars or real-time updates.
  2. PluginSetting – Handles the GUI dialog for API keys or symbol mapping.
  3. CreateComposite / DestroyComposite – Manages database connections.

7. API / Source Code Quality (for Developers)

If you are selling or sharing the source code, add these:

  • Clean separation – Data source transport layer (network) vs. Amibroker plugin interface.
  • Example implementation – e.g., plugin that reads from a simple CSV file or WebSocket demo.
  • Build scripts – CMake or Visual Studio project files for both x86 and x64.
  • Documentation – Inline comments explaining the Amibroker SDK (especially tricky parts like GetQuotesEx flags).
  • Thread safety – Proper mutex usage; Amibroker can call plugin functions from multiple threads.

Handling Historical Backfills (A "Top" Priority)

A data plugin is useless without proper historical daily/minute/ tick backfill. The GetStatic method is where top source codes shine.

The algorithm used in professional source code:

  1. Check local cache (SQLite or flat binary file).
  2. If missing, fire async HTTP request to data vendor.
  3. Parse response (CSV, JSON, or binary protobuf).
  4. Convert timezone to Eastern Time (AmiBroker’s internal clock).
  5. Write to cache and return StaticInfo array.

Timezone conversion snippet (Gold standard):

void ConvertToEasternTime(SYSTEMTIME *utc)
TIME_ZONE_INFORMATION tzi;
    GetTimeZoneInformation(&tzi);
    // Apply bias: UTC to Eastern = -300 minutes (standard)
    // Top plugins adjust for DST dynamically
    SystemTimeToTzSpecificLocalTime(&tzi, utc, utc);

Report: Investigation into "Amibroker data plugin source code top"

Summary

  • Objective: locate and assess availability, quality, and provenance of source code for Amibroker data plugins, particularly any projects or repositories referencing "top" (e.g., "top of book", "TOP" naming, or a repo named "top").
  • Scope: public repositories, developer forums, plugin documentation, and official Amibroker SDK resources.

Findings

  1. Official Amibroker resources
  • Amibroker provides an SDK and documentation for creating data plugins (Data Plugin SDK). This is the primary authoritative source for how plugins integrate with Amibroker—includes header files, interface specifications, and examples.
  • Official examples are typically distributed with Amibroker installations or available on the Amibroker website/documentation.
  1. Public source code availability
  • Several third-party data plugins have publicly available source code (GitHub, GitLab, Bitbucket). These vary in language (C/C++, sometimes C# wrappers) and quality.
  • Common repository contents: sample plugin implementations, DLL project files, README with build instructions, and sometimes binary releases.
  1. "top" keyword relevance
  • The term "top" appears in contexts like "top of book" market data or as part of repository names. No single dominant public repo named exactly "amibroker data plugin source code top" was found; results are scattered across multiple repos and forum posts.
  • Repositories with "top" in name more often relate to market data providers or proprietary tools rather than canonical Amibroker plugins.
  1. Community discussions
  • Active threads on Amibroker community forums, StackOverflow, and trading developer forums discuss building data plugins, common pitfalls (threading, callbacks, memory management), and vendor-specific adapters.
  • Some contributors share snippets rather than full plugins due to licensing or commercial restrictions.
  1. Licensing and legal notes
  • Many third-party plugins are closed-source or commercial; where source is published, licenses vary (MIT, GPL, permissive, or custom). Always check repo-specific license before reuse.
  1. Build and compatibility considerations
  • Data plugins are typically compiled as 32-bit or 64-bit DLLs matching the Amibroker installation and must implement required interfaces from the SDK.
  • Dependencies: Visual Studio toolchains, correct SDK headers, and sometimes vendor APIs for market feeds.

Recommendations (actionable)

  1. Start with the official Amibroker Data Plugin SDK and shipped examples to understand interfaces.
  2. Search GitHub/GitLab for repositories with keywords:
    • "AmiBroker data plugin", "AmiBroker dataplug", "AmiBroker data plugin example", "amibroker plugin data dll".
    • Add vendor names or "top of book" if looking for TOP-related feeds.
  3. Evaluate candidate repos for:
    • Recent activity, build instructions, required toolchain, and license.
  4. If a commercial/top-of-book vendor is target, contact vendor for SDK/API and licensing—most TOP feeds are proprietary.
  5. When adapting code, ensure binary architecture (32 vs 64-bit) matches target Amibroker and run sanitizers/debug builds for plugin stability.

Next steps I can perform (pick one)

  • Produce a step-by-step guide to build a simple Amibroker data plugin from the official SDK (assume Windows + Visual Studio).
  • Search public code hosts (GitHub/GitLab) and assemble a short list of existing repositories with links and short notes.
  • Summarize common implementation pitfalls and debugging tips for Amibroker data plugins.

Building a High-Performance AmiBroker Data Plugin: A Deep Dive into Source Code and Architecture

AmiBroker is renowned among quantitative traders for its blistering backtesting speed and flexibility. However, the software is only as good as the data feeding it. While many commercial vendors offer ready-made connectors, developing your own AmiBroker data plugin using the source code SDK allows for unparalleled customization—whether you’re plugging into a proprietary API, a crypto exchange, or a niche local database.

In this guide, we will explore the structural "top" tier of AmiBroker data plugin development, breaking down the C++ SDK essentials and how to optimize your source code for real-time performance. 1. The AmiBroker Development Kit (ADK)

To start, you need the AmiBroker Development Kit (ADK). This is a collection of C-style headers and sample C++ projects provided by AmiBroker's creator, Tomasz Janeczko. The ADK defines the standard interface that allows the Broker.exe process to communicate with external DLLs. Key Files in the Source:

Plugin.h: The core header file containing structure definitions like Quotations, StockInfo, and PluginInfo.

AmiRoot.cpp/h: Often used as the entry point for managing the connection lifecycle. 2. Core Functions Every Plugin Needs

When you look at the top-performing data plugin source codes, they all implement a specific set of exported functions. Without these, AmiBroker won't recognize your DLL. GetPluginInfo

This identifies your plugin to the system. It returns the name, vendor, and type of plugin (Data, Indicator, or Tools).

__declspec(dllexport) int GetPluginInfo(struct PluginInfo *pInfo) pInfo->Name = "Custom SQL Connector"; pInfo->Vendor = "YourName Quant Lab"; pInfo->Type = 1; // 1 for Data Plugin return 1; Use code with caution. GetQuotes

This is the "engine room." When AmiBroker needs data for a chart, it calls GetQuotes. A high-performance plugin source code should implement intelligent caching here. Instead of hitting your API every time a user scrolls, the plugin should store data in a local buffer. 3. Real-Time Streaming vs. Backfill

The "top" tier of plugins are those that handle both historical backfill and real-time "tick" data seamlessly.

Historical Backfill: 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.

Real-Time Streaming: Requires a multi-threaded approach. Your source code should have a background thread listening to a WebSocket or Socket connection, pushing new ticks into a thread-safe queue that GetQuotesEx can then drain. 4. Best Practices for Professional Source Code

If you are searching for "top" source code examples, look for these architectural patterns:

Thread Safety: Since AmiBroker may request data for multiple charts simultaneously, your internal data structures (like a std::map of symbols) must be protected by Mutexes or Critical Sections. Unlocking the Engine: A Deep Dive into Amibroker

Error Logging: Implement a robust logging system that writes to the AmiBroker "Log" window using SiteContext->LogMessage(). This makes debugging connection drops much easier.

Adaptive Polling: Top-tier plugins adjust their request frequency based on whether a symbol is currently being viewed or if it's just being updated in the background. 5. Where to Find Source Code Examples?

While the official ADK includes a "Universal Data Plug-in" sample, it is quite basic. For more advanced implementations, developers often look toward:

GitHub Repositories: Search for "AmiBroker Plugin C++" to find wrappers for modern APIs like Interactive Brokers (IBKR) or IQFeed.

AmiBroker Custom Dev Forum: A hub for veteran coders sharing snippets for specific data formats like JSON or Protocol Buffers. Conclusion

Writing an AmiBroker data plugin is a rite of passage for serious systems traders. By mastering the ADK and focusing on thread-safe, cached data delivery, you can build a connector that matches the speed of the software it feeds.

To develop an AmiBroker data plugin, you primarily need the AmiBroker Development Kit (ADK), which provides the necessary C++ headers and sample source code. For modern developers, there are also community-supported .NET alternatives that simplify the process. 1. Official AmiBroker Development Kit (ADK)

The official way to build a plugin is using the ADK, which includes the C++ API definitions and working examples for both indicator and data DLLs.

Latest Version: ADK 2.10a (supports 64-bit date/time and floating-point volume).

Core Files: Look for Plugin.cpp and Plugin.h within the Data_Template folder of the kit.

Documentation: The included ADK.html contains the full API specification for functions like GetQuotesEx.

Download: Available as a self-extracting ADK.exe or ADK.zip from the AmiBroker Download Page. 2. Open Source Examples & SDKs

If you prefer not to work directly in C++, several GitHub repositories provide modern wrappers and full plugin implementations: A AmiBroker Development Kit - GitLab

Data Flow in 64-bit vs 32-bit

Modern Amibroker (v6.0+) strongly prefers 64-bit plugins. The top source code repositories avoid the legacy 32-bit __stdcall conventions in favor of __fastcall for speed.

Memory Management Warning: A common bug in third-party source code is improper handling of QuoteEx arrays. The plugin must fill pQuote->fOpen, fHigh, fLow, fClose, nVolume atomically to avoid chart glitches.

4. Symbol Handling & Metadata

  • Dynamic symbol discovery – Provide a symbol list from the data source (e.g., from a broker API or CSV config).
  • Symbol mapping – Map external symbol names (e.g., AAPL from broker) to Amibroker symbols.
  • Market center / exchange filter – Allow user to enable/disable specific exchanges.
  • Watchdog for symbol status – Detect delisted or suspended symbols and notify Amibroker.

3. Historical Data Management

  • On-demand backfill – Automatically fetch missing history when Amibroker requests a symbol for the first time.
  • Intraday backfill – Support for tick, 1-sec, 1-min, 5-min, etc.
  • Adjustment for splits & dividends – Adjust O/H/L/C/V in the plugin before passing to Amibroker.
  • Smart caching – Local binary cache (e.g., using LMDB or custom flat files) to avoid re-downloading history.
