Pattern Detection
Pattern Detection AFL code for Amibroker, when integrated with Amibroker Data Feeder, is an essential tool for traders. It scans and identifies various technical patterns like triangles, head and shoulders, or flags within price movements. This code, when powered by real-time market data from Amibroker Data Feeder, assists traders in recognizing potential trade setups based on pattern formations.
//* HARMONIC PATTERN DETECTION
Automatic Detection of Harmonic Patterns - Gartley, Bat, Butterfly and Crab.
Zig Zag is not used in this AFL. It is based on fractals
