Every pre-session directional read is graded against the realised move from session open to session close. Flat sessions are reported separately and excluded from the rate.

FXBias publishes briefings for three sessions: Asia (00:00–09:00 UTC), London (08:00–17:00 UTC) and New York (13:00–22:00 UTC). London consistently produces the widest ranges on EUR and GBP pairs, Asia is the home session for AUD, NZD and JPY instruments, and New York carries USD-driven moves.
How is this data measured?
Every session, FXBias records the opening price of each instrument, then the high, low and close when that session ends. Session range is (high − low) ÷ open, expressed as a percentage and averaged per pair. Nothing is back-filled or simulated — each figure comes from a session that was recorded live, before it happened. Data as of July 2026, 1,839 pair-sessions recorded.
