Updated Opening Range Breakout
## Opening Range Breakout (ORB) — 8:30–8:45 CT
**What it does**
Marks the first 15-minute candle after the CME open (8:30–8:45 America/Chicago), locks that high and low as the opening range, then fires a single, no-repaint signal the moment price breaks the range for the first time. One trade idea per session — no spam, no flicker.
**How it works**
- Builds the range live from 8:30, locks it permanently at 8:45.
- **BUY** on the first break above the range high. **SELL** on the first break below the range low.
- If both sides break on the same bar, direction is resolved by where price closed relative to the range midpoint.
- Signal latches after firing — it will not repeat or repaint for the rest of the session.
**The one knob**
`Signal on wick break` — OFF (default) waits for a confirmed bar close before signaling (cleaner, fewer fakeouts). ON triggers the instant a wick pierces the range (faster, more noise).
**Built for**
NQ / MNQ index futures on the 8:30 CT open. Run it on a **1m–15m chart** — it warns you if the timeframe is too large for the range to build correctly.
**Alerts**
Two ready conditions: *OR Breakout — BUY* and *OR Breakout — SELL*, wired to the same latched logic as the on-chart labels.
