The spread across the day

The busiest hour is 10:00, averaging 12.75 per bar. The quietest is 19:00 at 3.00. That is a 4.2× difference across the same instrument, the same timeframe, the same trading day.

A stop sized for 19:00 conditions will be caught routinely at 10:00, and a stop sized for 10:00 gives away far more than it needs to overnight. The same number of points does not mean the same thing at every hour.

How this was measured

Every 15 minute bar of E-mini S&P 500 recorded in the last 90 days was grouped by the hour it opened, in Eastern time. The figure shown is the median of high minus low within each group — the middle bar of that hour, not the average, so a single outlier session cannot distort it. Hours with fewer than 60 recorded bars are omitted rather than shown on thin evidence.
