First-Hour Breakout Rules Using Prior-Day and Premarket Levels

Summary

This intraday strategy trades only within a configurable opening window and seeks long or short entries around the prior day’s high or low and the premarket high or low. Setups include a level retest, a first confirmed touch, or a pullback to the fast EMA. Directional filters can require price to align with VWAP and the fast and slow EMAs, while a location rule requires price to have moved beyond a relevant prior-day or premarket boundary. The example uses two units per trade and limits the number of daily trades.

Exit management combines a partial limit exit near a new regular-session high or low, an EMA-based stop, and a close-based trail tied to the fast EMA or entry level. The strategy also flattens positions near the market close. The source notes that partial fills in the tester are approximate and recommends replay or paper evaluation. It gives no reported performance results, and its behavior depends on chart settings, extended-hours data for premarket levels, and the execution assumptions used in testing.

Key ideas

• The strategy combines prior-day and premarket levels with retest, first-touch, and fast-EMA pullback setups.
• VWAP, EMA alignment, and price location act as configurable direction and entry filters.
• A partial exit can occur at a new session extreme, while the remaining position follows EMA and level-based exits.
• The strategy restricts entries to a first-hour window and flattens remaining trades near the close.
• The document reports no performance results and cautions that simulated partial fills are approximate.
