What it does
Round Number Levels keeps evenly spaced whole-number references on the chart around current price. It is built for traders who care about reactions near obvious psychological prices and want those levels visible without drawing them manually.
Who this is for
This page is a good fit for traders who want a readable Round Number 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
Round Number 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.

- The right interval depends heavily on the instrument and price scale.
- Round numbers matter more in some markets and sessions than others.
- These levels are references, not automatic signals.
