The spread across the day

The busiest hour is 10:00, averaging 7.25 per bar. The quietest is 19:00 at 1.75. That is a 4.1× 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 5 minute bar of Micro 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.
