The 3 Major Interbank Trading Killzones

Over 78% of daily forex volume transacts during two overlapping windows: the London Open and the New York Open. Algorithms programmed by tier-1 banks execute bulk order balancing during these specific temporal phases:

  • Asian Session Range (Accumulation): 00:00 – 06:00 GMT. Establishes the daily liquidity boundaries (Asian High & Low) subsequently hunted during London.
  • London Killzone (Manipulation & Trend Establishment): 07:00 – 10:00 GMT. Frequently forms the low of the day (in a bullish daily profile) through a false breakdown known as the Judas Swing.
  • New York Killzone (Expansion & Reversal): 13:00 – 16:00 GMT. US macroeconomic releases (NFP, CPI, Retail Sales) unleash high directional volatility.
