Amibroker AFL (AmiBroker Formula Language) is a versatile proprietary coding language that allows traders to customize indicators, trading systems, backtests, scans and more within the Amibroker platform. Amibroker AFL With adequate skills in amibroker afl, almost any custom requirement for trading analysis and strategy automation can be addressed.
This in-depth guide will cover the key aspects of amibroker afl programming as well as integration of live amibroker data feed market amibroker data feeds, to enable retail traders to unlock Amibroker’s exceptional strategy development capabilities.
amibroker afl is an acronym for Amibroker Formula Language. As the name suggests, it is a domain-specific programming language optimized for financial analysis and trading strategy development purposes.
The language uses a C/C++ like syntax which allows both procedural as well as object oriented coding constructs. amibroker afl has rich inbuilt functionality for technical analysis, statistics, matrix operations, graphics, dates and times. Expert coders can tap into additional mathematical, signal processing, pattern recognition capabilities for creating high performance strategies.
A typical amibroker afl script file consists of multiple blocks or sections for declaring variables, defining functions, strategy logic, trade entries and exits etc. Some key structural elements are:
Parameters Section: Input criteria that can be changed without affecting logic flow Variables Section: Defines variables types and assignments Init Section: Initializes variables values during first pass Analysis Section: Main strategy amibroker afl logic for computing indicators goes here Buy and Sell Sections: Entry and exit trade conditions defined Plot Section: Plots indicator values to chart for visualization
The modular approach facilities code re-use and keeps amibroker afl scripts well organized for easier troubleshooting.
Now that we understand amibroker afl structure, let’s see how to put it into practice for some common use cases:
Coding a Custom Indicator Formula
Building a Trading Strategy
The inbuilt amibroker afl Editor offers many productivity features like syntax highlighting, autocomplete suggestions, error checking and specific trading strategy templates to make coding easier.

Gaining proficiency in Amibroker amibroker afl opens up avenues to create advanced trading tools for gaining an edge in markets. Integrating various amibroker data sources expands possibilities for backtesting and automation across asset classes. With expanding digital datasets and platforms, amibroker afl presents new possibilities for traders to research and deploy winning quant strategies.
AFL stands for Amibroker Formula Language. It is a programming language used to create custom indicators, trading systems, and automation scripts within the Amibroker platform.
Learning AFL allows you to fully customize Amibroker as per your trading requirements by coding complex logic for indicators, strategies, backtests which is not possible using the UI.
Some common uses of AFL are developing indicators, trading systems, scans, data explorations, visualizations, screeners, automated trading systems, connecting to data feeds etc.
Some programming experience in languages like C++, Python, Java etc helps understand the syntax faster. No specific educational background is necessary. Focus is more on the trading domain logic.
Amibroker provides comprehensive AFL documentation and tutorials in the software. There are also dedicated books, courses, forums, blogs that share AFL code and videos.
While direct conversion is not possible due to Amibroker’s proprietary nature, the underlying logic conceptualized in AFL can be recoded into any mainstream programming language.
Yes, AFL has been specialized designed only for Amibroker platform and its associated ecosystem tools for strategy development. It is not a general purpose programming language.
Amibroker EULA allows developing trading systems for personal use. For commercial resale of AFL systems, special licensing needs to be purchased.
For consistency, it is recommended to code AFL scripts on same Amibroker version and machine configuration as you intend to run the AFL on. Cross-platform behaviour may have variations.
Some most widely used AFL functions are for technical indicators, simple/exponential moving averages, strategy signals, true range, highest-lowest values, date-time handling etc.
Mastering Amibroker AFL opens up immense opportunities for traders to research, analyze and automate custom quantitative trading strategies for consistent profits.
While the initial learning curve may seem daunting to some, by systematically going through documentation, taking up coding projects and getting help from forums, the journey gets progressively easier.
AFL allows creation of complex technical analysis measures and rule-based systems not possible otherwise. Integrating reliable data feeds unlocks brute-force backtesting at scale leading to statistical validation of strategy efficacy.
Automation ensures flawless execution without emotions, across markets and asset classes to tap into emerging algorithmic trading opportunities. The future likely promises expanding computing power and data availability, further elevating the scope of AFL applications.
For determined retail traders bitten by the quant trading bug, pursuing Amibroker AFL offers possibilities to reach that profitable sweet spot at the intersection of coding skills, data sources and trading opportunities. The time invested can provide rich dividends for years to come in the form of cash generating trading systems.
