AFL (Analysis Formula Language) is the scripting language used in AmiBroker – a popular technical analysis and backtesting platform. It allows you to create custom indicators, scans, explorations, trading systems, and backtests. 🧠 Basic Syntax & Core Concepts 1. Arrays vs Scalars AFL is array-based – most operations work on entire price series.
