Day of the week
Monday has the widest average daily range (5.54%), Friday the narrowest (4.80%). Only Monday shows an average open-to-close return that is distinguishable from zero at 95% confidence (marked •). Even then it is one measurement over a few years: check the year-by-year table before reading anything into it.

Monthly seasonality
Not shown: the feed has fewer than three complete years of homogeneous data for this market, too few to say anything about a calendar month.
Trading sessions
How much of the day's range happens inside each session, over the last 12 months. Sessions overlap, so the shares do not add up to 100%. A session with no prices in our feed is not listed.
| Session | Average range | Median share of the day's range | Days |
|---|---|---|---|
| London 08:00–16:30 London time | 494.8 bp | 100 % | 165 |
| New York 08:00–17:00 New York time | 392.1 bp | 80 % | 165 |
Volatility over the last year
ATR (14) as a percentage of the price, one point per trading day.
How it is measured
- One-minute bid prices from the cTrader broker feed we use for our own backtests: 165 complete trading days, 2026-03-09 to 2026-10-30. The feed for this market changed on 2026-03-09, so only the data since then is used.
- A trading day is the broker's: it closes at 17:00 New York time, as in cTrader. Partial days (holidays) are left out.
- Range = high − low of the period, as a share of its opening price. 1 bp (basis point) = 0.01%. ATR is Wilder's 14-day average true range.
- The hourly profile is measured in UTC and kept separately for US summer and winter time, so the hours shown in your time zone stay right all year.
- Updated every day after the market data sync. These are descriptive statistics of the past: they are not a forecast and not a trading signal.
