AmiBroker is a high-performance technical analysis and charting platform written in C++. To maintain its compact size—with executables totaling only about 3.5 MB—it relies on a modular architecture of Dynamic Link Libraries (DLLs).
Core Dependency: Brokey.dll is one of the three primary additional application files (alongside CoolTool.dll and MiscTool.dll) required by the main executable, broker.exe, to run.
System Integrity: Because it is a compiled machine-code library, it allows AmiBroker to process data at extreme speeds—up to 166 million data bars per second—without the overhead of virtual machines like Java or .NET. Common Contexts and Use Cases
While Brokey.dll is a standard system file, users typically encounter the name "Brokey" in three specific scenarios:
Software Installation and Troubleshooting:If the Brokey.dll file is missing or corrupted, AmiBroker will fail to launch. Users troubleshooting startup errors often have to verify that this file exists in the main installation directory (typically C:\Program Files\AmiBroker).
Plugin Development:The AmiBroker Development Kit (ADK) allows developers to create custom data plugins that interface with these internal libraries. "Brokey" acts as a bridge for these plugins to feed real-time or historical data—such as that from Interactive Brokers or Norgate Data—directly into the charting engine.
Third-Party "Cracks" and Security Risks:The name is frequently mentioned in unauthorized "crack" tutorials or modified versions of the software. Malicious actors often replace the original Brokey.dll with a modified version to bypass license checks. Users are strongly cautioned against this, as it compromises system security and software stability. The official software is available as trialware for evaluation.

While "Brokey" sounds like a slang term (often used in trading circles to describe a strategy that blew up an account), in the context of Amibroker data management, it refers to Broken Data Keys or Missing Data.
Amibroker relies on a robust database structure. It expects data to be continuous. However, data vendors often provide "dirty" data. Common issues include:
If your Amibroker database has these "holes," the backtester will skip over them or misinterpret them, leading to Survivorship Bias and wildly inaccurate results.
To understand the value of Brokey, you must understand the bias it corrects. AmiBroker, out of the box, is not biased—the data you feed it is biased.
Consider this example:
Your backtest will show a glorious 20% CAGR. In reality, that strategy would have been wiped out by the dot-com bust because you would have bought the broken stocks too.
The Brokey solution involves adding a “Brokey Flag” – a custom True/False indicator or a separate watchlist that includes all delisted stocks with their price path to zero. When you run a backtest in AmiBroker, Brokey scripts automatically:
Without Brokey, your optimization results are a fantasy.
Brokey is a utility/script used with AmiBroker to detect and manage broken/invalid data, symbol mismatches, or problematic bars that can cause analysis and backtests to produce incorrect results. It helps find gaps, duplicate timestamps, erroneous prices (e.g., zero or null), and misaligned symbol headers.
