New Highs & New Lows – Marker (with Equal Highs/Lows)

Description

This indicator automatically highlights new highs and lows on your chart. It works in two modes:

All-Time Mode (Lookback = 0): Marks all-time highs and lows since the start of the chart.

Lookback Mode (Lookback > 0): Marks new highs or lows relative to the last N bars.

Both new extremes and equal highs/lows (ties) can be visualized with different colors and shapes. Alerts are included so you can be notified as soon as new highs or lows appear.

Use this tool to quickly spot breakouts, double tops/bottoms, or potential support/resistance levels.
