Nasdaq-100 Futures Swung 704 Points Friday and Finished Down 350

Friday's regular session in E-mini Nasdaq-100 futures (NQ1!) covered 703.75 points — about 131% of the 20-day average range of 537.25 points, per the RTH Range Gauge, a free open-source indicator running on the 30-minute chart that TradingView user mbjx2daddy used for the observation. That puts the session in the 85th percentile of recent trading days.

The numbers frame the story. The open landed near 28,391, roughly level with Thursday's close. That opening area held as the high of the day at 28,399. Sellers then pushed straight through the morning, and the low printed in the 11:00 ET bar at 27,695.25 — almost 700 points below the open.

The afternoon told a different story. Buyers recovered about half of the morning drop, and the regular-session close (9:30–16:00 ET) came in around 28,038, down roughly 350 points on the day.

Which levels matter for next week?

The analysis flags five concrete price levels for traders to watch when markets reopen:

• 28,391 to 28,399 — Friday's open and high, the area sellers defended all day.
• About 28,040 — Friday's close, the middle of the afternoon recovery.
• 27,695 — Friday's regular-session low.
• 27,516 — Tuesday's low and the low of the week.
• 28,697 — Wednesday's high and the top of the week's range.

Together those levels map the full week's structure: a ceiling sellers held on Friday sits near the top, and the week's floor at 27,516 sits roughly 180 points below Friday's intraday low.

What does the outsized range signal for Monday?

With Friday's range running well above average, the gauge starts Monday from a high-volatility reference point. The author lays out a simple test. If Monday's range passes about half of the 537-point average within the first hour, that would point to another wide trading day. A slow first hour under that pace would hint at a quieter, rotational session held inside Friday's range.

That's the practical takeaway: the first 60 minutes of trading on Monday becomes the tell. Half the average range — roughly 268 points — inside the opening hour flags continued volatility; anything slower suggests the market consolidates within the boundaries Friday set.

For context on the shape of the week, the broad arc runs from Tuesday's low of 27,516 up to Wednesday's high of 28,697 — a weekly span of more than 1,100 points — before Friday's open-high, midday-crash, half-recovery session closed near 28,038. Monday's opening hour will show whether that volatility persists or fades.
