Concept
The London session (0200-0800 EST) establishes the day's initial liquidity pools. As institutional order flow shifts to New York, price frequently seeks out these levels to fill resting orders before committing to directional moves. Historical data suggests approximately 86% of New York sessions will trade through at least one London session extreme.

How To Use
- London High/Low: Watch for sweeps of these levels during early New York session (0830-1000 EST). A sweep followed by rejection can signal reversal setups.
- 50% Level: Acts as equilibrium. After a liquidity sweep, price often retraces to this midpoint before continuation. Useful for target placement or secondary entries.
Best Practices
- Combine with market structure and session timing
- Most effective on ES, NQ, and forex majors
- Works on 1m-15m timeframes for intraday execution
