Using the First-Hour Range to Mark Open-Range Breakout Levels

Summary

The document explains an open-range breakout indicator that tracks the highest and lowest prices during the first hour of a trading session. In its default example, the measurement window runs from 9:00 to 10:00 in a European time zone. Those extremes define potential support and resistance levels; traders watch for price to break beyond the range. The indicator also plots levels at half-range increments above and below the measured range, which can serve as additional reference points.

The included indicator logic accumulates the session high and low during the specified window, then calculates and displays the range boundaries and extensions. The author notes that users can change the time parameters for other windows. The document gives no entry confirmation rules, stop placement, position sizing, or performance evidence, and it does not discuss how results may vary by instrument or session. The levels are therefore chart references for a breakout approach, not a complete or validated trading system.

Key ideas

• The indicator records the high and low during a configurable opening window.
• The first-hour extremes are treated as potential support and resistance for breakout monitoring.
• It plots additional reference levels at half-range increments beyond the opening range.
• The default measurement period is 9:00 to 10:00 in a European time zone.
• The document provides no tested performance or complete trade and risk rules.
