Session Liquidity Cycle: From Asia Range to Weekly Open
Market behavior is not random. Liquidity builds in Asia, is manipulated in London, and resolves in New York. Weekly Open becomes meaningful only under the right conditions.
Research Overview
This page presents a unified research framework linking Asia session range conditions, London liquidity sweeps, New York directional behavior, and Weekly Open reach probability. Each component is not treated as an isolated signal, but as part of a continuous liquidity cycle observed across trading sessions.
Session Liquidity Cycle
Step 1 — Asia Range
Liquidity accumulates during the Asia session. The size of the Asia range determines whether subsequent price action is efficient (expansion) or inefficient (no expansion).
Step 2 — London Sweep
The London session frequently engages resting liquidity above or below the Asia range. This phase acts as a manipulation, redistributing liquidity before directional movement emerges.
Step 3 — New York Resolution
The New York session reveals whether the prior sweep resolves into continuation, rebalancing, or non-expansion behavior. This phase determines the validity of directional bias.
Step 4 — Weekly Open Reaction
Weekly Open often acts as a magnet only after liquidity has been built and redistributed. When Asia builds range and London sweeps liquidity, New York tends to resolve directionally toward or away from Weekly Open depending on expansion efficiency. This relationship suggests that Weekly Open is not a standalone level, but the final stage of the session liquidity cycle.
Key implication:
Weekly Open reach probability increases when London sweep is followed by New York directional expansion, especially under moderate Asia range conditions.
Observed Example
Asia builds liquidity → London sweeps → NY resolves → Weekly Open reaction

Key Findings
- Asia range size strongly affects later session efficiency
- London sweep acts as a recurring manipulation phase
- New York behavior determines directional resolution
- Weekly Open functions as a conditional target, not a universal one
