Amibroker Afl Code [top]

AmiBroker Formula Language (AFL) is a high-level, C-style scripting language used to create custom indicators, trading strategies, and scans within the AmiBroker platform. It is designed for rapid execution by processing entire arrays (vectors) of data at once, which eliminates the need for many slow loops common in other languages. 1. Core Capabilities of AFL

// --- Input parameters --- FastMA_period = Param("Fast MA Period", 10, 2, 50, 1); SlowMA_period = Param("Slow MA Period", 30, 5, 200, 1);

While array processing is the default, AFL also supports standard programming constructs like if-else statements, for and while loops, and user-defined functions. These are essential for "path-dependent" logic, such as trailing stops or complex money management rules that cannot be calculated using arrays alone. amibroker afl code

AmiBroker Formula Language (AFL) is a high-performance scripting language used for technical analysis, backtesting, and automated trading within the AmiBroker platform. It is widely regarded in the trading community for its array-based processing, which allows it to handle large datasets significantly faster than many competitors.  Core Capabilities 

For a "proper" piece of AmiBroker Formula Language (AFL) code, it is essential to include structural elements that define signals, handle visualization, and manage trading parameters. Essential AFL Structure AmiBroker Formula Language (AFL) is a high-level, C-style

3. Check for Nulls

Frequently, Buy array becomes null. Use Buy = IIf(IsNull(Buy), 0, Buy);

At its heart, AFL operates on arrays—lists of numbers representing prices (Open, High, Low, Close) or volumes over time. This structure allows traders to write complex mathematical formulas with minimal code. Instead of using slow loops to process every bar in a chart, AFL performs operations on entire arrays simultaneously, which significantly boosts execution speed during backtesting. 2.
