The hours that produce the extremes
| Hour (UTC) | Session | Highs | Lows |
|---|---|---|---|
| 14:00–15:00 UTC | London/New York overlap | 8.3% | 7.3% |
| 13:00–14:00 UTC | London/New York overlap | 6.2% | 7.2% |
| 15:00–16:00 UTC | London/New York overlap | 6.6% | 6.4% |
| 07:00–08:00 UTC | London | 6.3% | 5.6% |
| 12:00–13:00 UTC | London/New York overlap | 5.4% | 6.3% |
| 08:00–09:00 UTC | London | 5.1% | 5.4% |
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.
