Detecting Session Range Sweeps with Locked Levels and Reaction Zones
Summary
This indicator measures high and low prices during configurable Asian, London, and New York trading windows, then freezes each range when its session ends. It flags a sweep only when a later bar penetrates a locked boundary by a minimum amount and closes back within the range. A close beyond the boundary is treated as a breakout instead. Arrows identify the swept side, and a shaded zone marks the nearby area for possible reversal entries or stop placement.
The document describes inputs for session hours, history depth, minimum penetration, alerts, and chart markings. It recommends checking broker server time and adjusting for daylight-saving differences. The author says signals are confirmed after a bar closes and do not repaint. The approach is presented as most readable on intraday charts; bars that span session boundaries can blur range calculations on higher timeframes. No performance testing or evidence that sweeps predict profitable reversals is provided.
Key ideas
- Session highs and lows are accumulated during configurable trading windows and locked when each window ends.
- A sweep requires price to cross a locked level by a minimum distance and close back inside the range.
- A bar that closes beyond a range boundary is treated as a breakout, not a sweep.
- Arrows and shaded rectangles mark the sweep direction and a nearby reaction area.
- Broker server time, daylight-saving changes, spread noise, and chart timeframe can affect interpretation.
