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. Buy = Cross(oversold, rsi); // RSI rises above
// Calculate RSI rsi = RSI(rsiPeriod);
// Plot Plot(Close, "Price", colorBlack, styleCandle); Plot(macd, "MACD", colorRed, styleLine); Plot(signal, "Signal", colorBlue, styleLine); Plot(hist, "Histogram", colorGreen, styleHistogram); Arrays vs Scalars AFL is array-based – most
// Mark buy/sell on chart PlotShapes(Buy * shapeUpArrow, colorGreen, 0, Low, -10); PlotShapes(Sell * shapeDownArrow, colorRed, 0, High, -10); rsiPeriod = 14; overbought = 70; oversold = 30; rsi = RSI(rsiPeriod);
