Last-hour breakout patterns, direction, and extension
The last hour of trading (3:00-4:00 PM ET) — "power hour" — often brings a surge in volatility as institutions finalize positions, MOC (Market on Close) orders execute, and traders square up. This report tracks breakout frequency and quality during this window.
| Metric | Typical Value |
|---|---|
| Breakout Frequency | 40-55% of sessions |
| Average Extension | 0.3-0.6% from breakout level |
| Continuation Rate | 55-65% continue into next day open |
| Peak Volume Time | 3:45-3:55 PM ET (MOC orders) |
Wait for a break of the 2:30-3:00 PM range, then trade in the breakout direction with momentum. Power hour breakouts that align with the day's trend have higher continuation rates. Use a tight trailing stop — the move can be sharp but also whipsawing.
