What it does
Session Levels keeps the main prior-session prices on the chart while you trade lower timeframes. It is built for traders who want a quick map of where price sits versus yesterday's structure and today's open.
Who this is for
This page is a good fit for traders who want a readable Session Levels workflow without having to reverse-engineer the setup from forum posts or screenshots.
Key terms for this tool
Review the core trading and platform terms tied to this page before changing settings or using the study in a live workspace.
What it is not
Session Levels is a chart-context tool. It does not place trades, manage risk automatically, or promise that a specific pattern will resolve in one direction. Use it to organize decisions, not to outsource them.

- Session templates directly affect the levels.
- Too many levels can clutter the chart.
- Levels show context, not automatic trade decisions.
