Overview

This page describes the methodology used by the eXpeed Research Lab to analyze liquidity behavior and market structure events across major FX trading sessions. The objective of this research is not to provide trading signals, but to examine recurring structural patterns associated with session liquidity, sweeps, displacement, and market structure shifts.

Data Sources

The analysis is based on historical price data from major FX pairs, with a primary focus on EURUSD and GBPUSD. All observations are derived from time-based session segmentation and rule-based event detection implemented in Pine Script.

Session Segmentation

Market activity is segmented into three major trading sessions :

– Asia Session
– London Killzone
– New York Session

This session-based segmentation allows the study of liquidity accumulation, sweep behavior, and displacement events across the trading day.

Event Classification

The research framework focuses on the following event types :

  • Liquidity Reservoir
  • Liquidity Sweep
  • Displacement
  • External Market Structure Shift (External MSS)
  • Fair Value Gap (FVG)
  • Judas behavior

These concepts are treated as structural observations rather than predictive guarantees.

Detection Logic (Extended)

All events are detected using deterministic rule-based conditions implemented in Pine Script. To ensure consistency, each condition is defined using objective price behavior rather than subjective interpretation.

Examples :

  • Liquidity Sweep:
    A break of prior session high/low followed by immediate rejection or failure to continue.
  • Displacement:
    A strong directional move defined by range expansion exceeding a multiple of recent average range.
  • London Raid:
    A liquidity sweep occurring during the London Killzone, typically targeting Asia session highs or lows.
  • Judas:
    A false directional move during early session that reverses and leads to expansion in the opposite direction.

All detections are processed sequentially and aggregated for statistical evaluation.

Research Framework

The research framework follows a sequential model :

Liquidity Accumulation → Liquidity Sweep → Displacement → Structural Shift → Continuation or Reversal

・Session Liquidity Cycle

・External MSS Model

・London Raid Model

The London Raid model represents a specific case within the broader liquidity framework, where Asia session liquidity is swept during the London Killzone, often leading to displacement and continuation toward the New York session.

Limitations

This methodology is designed for observational research and statistical study. The models described on this site do not guarantee future outcomes and should not be interpreted as financial advice or a standalone trading system. All findings are subject to sample limitations, market regime changes, and rule-definition constraints.
