When the Daily High and Low Actually Form

If a day's extremes were scattered at random, each hour would hold about 4.2% of them. They are not scattered. On GBP/USD, 8.3% of daily highs form between 14:00–15:00 UTC — roughly double chance.

How this was measured. Computed from 1,898,746 one-minute GBPUSD candles covering 2021-01-03 to 2026-04-30 — 1,595 trading days. Range means high minus low over the stated period, grouped by real clock time in UTC rather than by bar count, so an hour is an hour even across a weekend. Figures are in pips. The underlying numbers are published as JSON at https://fxabsolute.com/stats/GBPUSD.json.
One figure is excluded, and here is why. The 00:00 UTC hour shows 8.7% of highs and 9% of lows — the largest in the table — and that is an artifact of where the day is cut. The first minute of a UTC day initialises both running extremes, so any day that never trades beyond its opening minute records its high or low in hour zero. The FX week actually opens near 22:00 UTC, making the boundary arbitrary. Hour zero is shown below for completeness and left out of the ranking.

The concentration sits where the volume does. The three busiest hours together account for 21.1% of highs against the 12.6% chance would give them.

What this is useful for

Mostly for knowing when a range is not yet set. A breakout rule that triggers at 09:00 UTC is acting on a range that still has its most likely extreme ahead of it. That is not an argument against the rule — it is an argument for knowing which half of the distribution it is trading in, and for not treating a morning high as the day's high.

It also says something about exits. A target placed at the prior day's extreme is being placed at a level most likely to be revisited in the afternoon, not the morning.

Questions

What time does the daily high usually form in forex?

Most often in the 14:00–15:00 UTC window on GBP/USD — 8.3% of days, against the 4.2% each hour would hold if it were random. The London and New York hours dominate.

Why does 00:00 UTC show the most extremes?

Because it is where the day is cut, not because the market does something there. The first minute of a UTC day sets both running extremes, so any day that never trades past its opening minute records an extreme in hour zero. It is excluded from the ranking for that reason.

Can this be used to time entries?

Not on its own. It says when a range is likely still incomplete, which is a caution about treating an early extreme as final — not a signal.
