An opening range breakout trades the first move out of a session's opening high and low. Definition, rules, crypto and stock-perp ranges on Nov 9, 2026.
What is an opening range breakout? An opening range breakout (ORB) marks the high and low a market makes in the first minutes of a session, then trades the first decisive move out of that range: long above the high, short below the low. The range is the reference; the breakout is the trigger.
Key takeaways
- The opening range is usually the first 5, 15, 30 or 60 minutes of a session.
- Stocks have a real open (9:30 AM ET on the NYSE). Crypto trades 24/7, so traders pick a clock: 00:00 UTC, the London open or the US open.
- The stop usually sits at the other side of the range, or the range midpoint, so a narrow range means a tight stop.
- A breakout that is already stretched far past the range, or happens on thin volume, is the one most ORB rules skip.
Opening ranges on Hyperliquid, Nov 9, 2026
The table shows a one-hour opening range for four crypto perps (the first hour after 00:00 UTC on Monday, Nov 9) and for two stock perps on the XYZ market (the first hour after the NYSE open on Friday, Nov 6), and where each price stood at the snapshot.
| Market | Opening range window | Range high | Range low | Range width | Price at 10:53 UTC Nov 9 | Where price sits |
|---|---|---|---|---|---|---|
| BTC | 00:00 to 01:00 UTC, Nov 9 | $75,257 | $74,449 | 1.09% | $74,118 | below the range |
| ETH | 00:00 to 01:00 UTC, Nov 9 | $2,146 | $2,116 | 1.38% | $2,109 | below the range |
| SOL | 00:00 to 01:00 UTC, Nov 9 | $87.56 | $86.20 | 1.58% | $85.92 | below the range |
| HYPE | 00:00 to 01:00 UTC, Nov 9 | $75.42 | $74.14 | 1.73% | $72.91 | below the range |
| xyz:SP500 | 14:30 to 15:30 UTC, Nov 6 (NYSE open) | $7,447 | $7,369 | 1.05% | $7,418 | inside the range |
| xyz:NVDA | 14:30 to 15:30 UTC, Nov 6 (NYSE open) | $194.89 | $190.00 | 2.57% | $178.49 | below the range |
Crypto opening ranges can be narrow: BTC’s first hour spanned 1.09% and HYPE’s 1.73%. A stop at the far side of a range that tight sits inside ordinary noise, which is why many traders only take ORB signals on stock perps at the real open, or require a minimum range width before they trade.
The rules most ORB versions share
- 01Pick the session clock and the range length, and keep them fixed.
- 02Wait for the range to finish. Do not trade inside it.
- 03Enter on a close beyond the range, not an intrabar poke, and require volume above its recent average.
- 04Put the stop at the opposite side of the range or its midpoint, and size the position so that stop costs a fixed share of the account.
- 05Exit at a target (often one or two range widths), at a trailing stop, or at the end of the session.
Running an ORB on Senpi
Describe the rule in a sentence to your Senpi agent, in the app or from Claude, ChatGPT or another AI app through the connectors. Senpi shows the rules back to you, then runs them in a separate strategy wallet with the stop attached from the first fill. Two open-source templates in the Senpi skills library are built on session opens:
- Oryx, XYZ intraday breakout: watches commodities and indices form a session range and trades the break with volume, skipping moves that are already extended.
- Rooster, the opener: wakes 45 minutes before the US equity open and trades BTC when it is already drifting one way on real volume.
ORB in 24/7 markets
Crypto has no closing auction, so an opening range only exists if you define one. A range that forms on a quiet weekend morning carries less information than one that forms at a stock market open with real order flow.
Does the opening range breakout work in crypto?
It can be traded, but crypto has no official open, so the range depends on the clock you choose: 00:00 UTC, the London open or the US open. On Nov 9, 2026 the first hour after 00:00 UTC spanned 1.09% on BTC and 1.73% on HYPE; a narrow range leaves little room for a stop.
What timeframe is best for an opening range breakout?
Common choices are 5, 15, 30 and 60 minutes. Shorter ranges trigger more often and get stopped more often; longer ranges trigger less often with wider stops. Pick one and keep it fixed, so results are comparable.
Where do you put the stop on an ORB trade?
Usually at the opposite side of the range, or at its midpoint for a tighter stop. Size the position so the distance to that stop costs a fixed share of the account, such as 1%.
Can I trade an opening range breakout on stocks with Hyperliquid?
