The AmiBroker Development Kit (ADK) prescribes a set of exported C-style functions. When AmiBroker loads, it scans the Plugins directory, registers compatible DLLs, and executes specific callbacks based on user actions or timer loops.
Amibroker uses a set of data structures to represent financial data, including:
// 3. GetQuotesEx: The core data delivery engine __declspec(dllexport) int GetQuotesEx(LPCTSTR ticker, int period, int nSize, struct Quotation *pQuotes, struct RecentInfo *pRecentInfo) // period defines the interval (e.g., daily, 5-minute, tick) // nSize is the maximum number of bars AmiBroker can accept in the current buffer // Example mock data generation loop // In a real plugin, replace this with your API/Database fetch logic int barsToReturn = (nSize > 100) ? 100 : nSize; for (int i = 0; i < barsToReturn; i++) // Populate timestamps (Example: Daily bars stepping backward) pQuotes[i].DateTime = GetAmiBrokerPackedDateTime(i); pQuotes[i].Open = 100.0f + i; pQuotes[i].High = 105.0f + i; pQuotes[i].Low = 95.0f + i; pQuotes[i].Price = 102.0f + i; // Close price pQuotes[i].Volume = 10000.0f; // Return the actual number of bars written to the array return barsToReturn; Use code with caution. Step 3: Managing Workspace and Configuration
When a new price tick arrives in your background thread, parse it and notify AmiBroker using the Windows messaging API: amibroker data plugin source code top
Amibroker is a popular technical analysis and trading software used by millions of traders and investors worldwide. One of its key features is the ability to integrate with various data sources, allowing users to access a vast array of market data. In this article, we will explore the Amibroker data plugin source code, its benefits, and provide a comprehensive guide on how to use it.
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
Set up a Module Definition File ( .def ) to explicitly declare your exports and prevent C++ name mangling. The AmiBroker Development Kit (ADK) prescribes a set
Notice the CRITICAL_SECTION . Top developers ensure thread safety because AmiBroker calls the plugin from multiple threads (UI refresh, backfill, real-time tick gathering).
If a market data feed sends 50 ticks per second for a single symbol, do not update AmiBroker on every single tick. Buffer the ticks and flush them to AmiBroker at a controlled interval (e.g., every 100ms).
Access the for the base source files and documentation. In this article, we will explore the Amibroker
This is what separates basic plugins from "top" ones.
Set the path directly to your target AmiBroker executable ( C:\Program Files\AmiBroker\Broker.exe ).
