Measured, not guessed · 2003..2026 of H1 data

When does EUR/GBP actually rise?

Every hour below is a real measurement: how often EUR/GBP closed higher than it opened in that hour of the week, across 58,437 hourly bars. Not signals — base rates, with the sample size on every figure.

The strongest and weakest hours

Averaged across the trading week, the hour that has leaned up hardest is 21:00 UTC — EUR/GBP closed higher 60.5% of 2,469 times there, far enough from a coin flip to be beyond chance. The weakest is 20:00 UTC, closing higher only 31.5% of 2,432 times.

Hour × weekday, the whole picture

Colour is the up-rate — red leaned down, teal leaned up. The brass dot marks buckets whose lean is statistically beyond chance at |z|≥3. Most cells have no dot. That is the honest shape of the market: mostly noise, with a few stubborn corners.

The three most stubborn corners of the grid:

• Wednesday 20:00 UTC — closed lower 70.8% of 486 times (z=-9.2)
• Tuesday 20:00 UTC — closed lower 70.1% of 488 times (z=-8.9)
• Monday 20:00 UTC — closed lower 67.6% of 488 times (z=-7.8)

Days and seasons

Weekday	Up-rate	Sample
Monday	49.0%	n=11,723
Tuesday	48.8%	n=11,711
Wednesday	50.0%	n=11,663
Thursday	49.1%	n=11,614
Friday	48.1%	n=10,382
Sunday	58.3%	n=1,344

Wednesday has been the friendliest day (50.0% of 11,663), Friday the least (48.1%). By calendar month, December leads at 50.8% and May trails at 47.8% — month buckets carry roughly a twelfth of the sample each, so hold them more loosely than the hourly figures.

Did any of it survive a real backtest?

Colours are description. A different question is whether a simple rule built on them — enter at the open of a bucket, exit at its close, pay a realistic spread — would have made money, and kept making it on data it was never fitted to. We ran that test across 5,086 rules on the whole board: 307 finished net positive, and only 214 survived the held-out final third of the history.

6 of those survivors run on EUR/GBP. The strategy board lists every one — including the losers, because a leaderboard that only shows winners is lying by omission.

Read it without fooling yourself

• The percentage is the headline, not the story. 60.5% from 2,469 samples is information; the same figure from 40 samples is noise. Every number here carries its n.
• The dots matter more than the colours. A vivid cell with no dot is well inside what chance produces.
• Direction is free; getting paid is not. A reliable lean smaller than your spread costs more than it earns.
• These are frequencies, not forecasts. 8 years of "usually" contains every kind of "except when".

The guide walks through all four traps with live numbers.
