Key terms for this guide
These glossary pages cover the ideas and platform language most closely tied to this workflow.
Session handling matters first
An opening range indicator is only as useful as its session definition. Futures, equities, and extended-hours charts can all produce different opening windows and different signals.
- The opening window must match the session you actually care about.
- RTH and extended-hours charts often produce different ranges.
- If the session definition is off, the rest of the logic is off too.
Use the range as context
Opening range highs, lows, and midpoints are reference levels. They become more useful when paired with volume, speed, or broader session context rather than treated as automatic entries.
Know when the range is locked
Some tools keep updating until the range window closes. Others mark only the completed range. Make sure you know which behavior your chart is showing.
- A moving range and a completed range support different decisions.
- This matters most around the open when traders are acting fast.
- Good documentation should make that behavior obvious.
