Overview

Users select five anchor points (X, A, B, C, and D) directly on the chart via interactive input prompts. The script evaluates the coordinates and plots Fibonacci ratios, potential reversal zones (PRZ), and shaded triangle fills for patterns like Gartley, Bat, Butterfly, Crab, Cypher, Shark, and Nenstar. Settings control pattern selection, error tolerance percentage, and visual elements.
