The London-to-New-York handoff is a change in participation, not a magic reversal window. The US pre-open brings a different calendar, liquidity profile, and relationship to regular cash trading.
Compare whether the US session inherits London range, tests its extremes, or reprices away from it before the cash open. The same framework applies to Asia earlier in the day.
LiquidityLevels publishes the handoff as context rather than treating the clock alone as a forecast.
