summary: ORB breakout and breakdown levels are shown as percentages of the opening range, not points. here's what that means, how to read the levels, and where the by-size report fits.

in the ORB strategy, breakout and breakdown levels are expressed as percentages of the opening range size, not points.

so when you see extensions like 0.5x, 1x, or 1.5x, those describe how far price moved relative to the ORB. a 1x extension means price moved the full width of the opening range beyond the breakout level.

why percentages instead of points? it keeps things comparable across days. a small opening range on a quiet day and a wide one on a busy day can be read on the same scale, so you can compare the data instead of chasing raw point values that shift with volatility.

whether a level counts as broken depends on your breakout criteria. the standard read and the stricter by-close read count breaks differently, and that difference is the usual reason a move you saw on your chart isn't logged the way you expected.

rather than repeat it here, the full walkthrough lives in one place: wick vs close — and what "broken" means across reports. check which read you're on and make sure you're looking at your chart the same way.

a double break is a session where price takes out both sides of the opening range; a single break is just one side.

if a move you thought was a double break shows up as a single, it's almost always the wick-vs-close setting above, or a session-window or timezone mismatch — the second side happened in a different trading day or session than the one the report is measuring. confirm you're on the same session and timezone as the report, then double-check your breakout criteria.

this is where it gets useful. the "ORB by size" report breaks down the data by the percentage size of the opening range — so you can see how different-sized ORBs tend to play out.

do smaller ORBs lead to bigger extensions? do larger ORBs tend to fail more often? the by-size report answers those questions with actual data.
