This script implements a nested fractal-based indicator that identifies potential buy and sell signals by analyzing fractal patterns in price action. It calculates larger and smaller fractal highs and lows and uses these patterns to confirm entry points. When smaller fractals appear within the range of larger fractals, the script generates buy or sell signals, which are plotted on the chart as visual markers. The logic is based on detecting price turning points through fractal analysis without any further complexity or additional filters.
