summary: the ORB report shows how price behaves after breaking the opening range. this is the trade-it layer: the number to read, what to do with it, a worked example, setup, and what to check when it looks off. for the full breakdown of all 9 variants, see which ORB report should I use?

the opening range is the first 15 minutes of your session (customizable). the report answers: after that range is set, how often does price break out, in which direction, and how far does it run?

ORB is the faster cousin of the IB. the range is shorter (15 minutes vs the IB's 60), so it breaks more often and earlier, but each break carries a smaller initial range.

start with the standard view: the overall breakout rate and the direction lean. look for a comfortable majority before you lean on it — the further clear of a coin flip, the better. a strong directional skew is a read you can trade. a near-even split is a day to sit out.

if the range breaks consistently with a clear lean, trade the break in the direction the data favors. then layer two reads to build the full trade:

if standard shows a strong breakout rate but by-close shows most breaks fade back inside by the close, that's a scalp, not a swing into the close. let the data pick the hold time.

say you're on ES, NY session. standard shows a solid breakout rate, by-levels shows price reaches the 50% extension a high share of the time on "first break," and by-close shows breakouts tend to hold.

the plan: trade the first clean break, target the 50% extension, and because closes tend to hold, you can give a runner room into the session. invalidate on a close back inside the range.

the edge is in the data. the result still takes customizing it to your instrument and managing the trade with discipline.

the opening range is defined by your session. an ORB on NY (9:30 to 9:45 AM ET) is a different range than London or Asia. set the session you trade, then match your TradingView timezone to it so the levels line up.

one gotcha for the 9:30 open: don't use a 60-minute candle to capture it. a 60-minute candle starts on the hour and skips the 9:30 open entirely. use a 15-minute candle for the ORB window.

the opening range is only the setup — the report measures what price does with it afterwards. so the session has to extend past the range, or there's nothing left to measure.

a break only counts if it lands inside the session window. if price breaks the range after your session ends, the report doesn't count it. and if your ORB timeframe is the same length as the session it sits in, the range completes exactly as the session ends — leaving no room for a break at all, and a report that comes back blank.

this bites most often on a custom session. a 60-minute opening range on a custom 8:00–9:00 AM session returns nothing: the range fills the whole session. the same 60-minute range on an 8:00 AM–4:00 PM session leaves the rest of the day for the break to happen.

so set the session end to give the break enough room, but keep it tight enough that you're still measuring the behaviour you actually trade. two settings decide this together — the length of the range, and the length of the session — and it's the relationship between them that matters, not either one on its own.

the IB report follows the same rule; see custom time ranges and sessions for the initial balance (IB) report.
