What is All Time High (ATH) Levels?
All Time High (ATH) Levels marks levels tied to record highs together with support and resistance candidates. A blue stepped line and a shaded band follow the record high, teal lines sit on the downside, and crimson lines sit on the upside.
The indicator does not print buy or sell arrows. It is used to see where an advance tends to stall and how far a pullback has travelled before the move is worth reassessing.
How to use All Time High (ATH) Levels
Read the lines as a map of how far price has travelled from its record high:
- While an advance continues, watch how far price pulls back after each new high.
- When price reaches the teal lines, check whether it steadies there or cuts straight through.
- When price approaches the crimson lines, watch whether the upside becomes heavy or a new high follows, without assuming a touch must reverse.
- Use Show Last ATH, ATH Minimum Duration, and Minimum Distance Between ATH to control how much record-high history stays visible, and the Style Inputs for the line colors.
Where it helps
The plotted lines show how far price has retraced after a new high instead of leaving it to feel, teal and crimson lines separate the downside and upside candidates without drawing every level by hand, and watching an approach to an upper line makes it easier to plan a target before a position is open.
