Study scenario

Mark an example 09:30–10:00 window and extend levels to describe structure only.

The time window depends on the market and the user's study plan. The indicator does not generate trade recommendations.

Common mistakes

  • Issue: Time zone or Session shifts the range.

    Check the input, version, session, data, or setting that controls this behavior.

  • Issue: Bars outside the window are included.

    Check the input, version, session, data, or setting that controls this behavior.

Lesson summary

  1. 01

    Time zone defines the window.

  2. 02

    Extremes come from in-window bars.

  3. 03

    Extended lines show structure.

PRACTICE EXERCISE

Check independent resets across two historical days with Jason Opening Range.

Use static, historical, or browser-local sample data only.
