The first 30 minutes set the day

The opening range is the high and the low of the first 30 minutes of the US trading day. On index futures, that means from 9:30am to 10:00am Eastern. You watch where price travels in that half-hour, mark the highest tick and the lowest tick, and draw two horizontal lines across the chart. That's the opening range. Two lines. That's it.

Wick points at a practice chart where price pushes above the 9:30 to 10:00 range high, showing a range break sets a direction bias that still needs context before any plan.Opening range breakPractice chartBreakRange high
Wick saysA clean break of the opening range gives you a bias, not a trade by itself.

Why does it matter? The opening range captures the moment when overnight positioning collides with US cash market flow. Funds rebalancing, retail orders piling in, news being priced in — all of it lands in the first 30 minutes. The high and low of that window become the day's first real reference points. Price holding inside the range often means indecision. Price breaking cleanly through the range often defines the rest of the day's direction.

Three things to watch when the range breaks. One, volume — a break on rising volume is more trustworthy than a break on thin volume. Two, time — a break in the first 15 minutes after the range completes is stronger than a break that finally happens at 2pm. Three, follow-through — does price hold the break, or does it pull right back inside the range? Failed breaks (price returns inside) are themselves tradeable signals, but the wrong direction.

Wick points at a practice chart where a 12:45pm break on thin volume falls back inside the opening range, showing a late, weak break is often a false move.Thin volume breakPractice chart12:45 breakBack inside
Wick saysA late, thin break that slips back inside the range is a warning, not a go.

Variants you'll meet. The 15-minute ORB uses only 9:30-9:45 — faster signal, more whipsaws. The 60-minute ORB uses 9:30-10:30 — slower signal, fewer false breaks. Different traders prefer different windows. Start with the 30-minute version because the data on it is the cleanest, and adjust based on what you find in your own journal.

Wick saysCheck volume, time, and follow-through before you trust a range break.

Recap: opening range is the high and low of 9:30-10:00 ET. Break above = bullish bias. Break below = bearish bias. Watch volume, time, and follow-through. ORB is a framework, not a signal.
