Crypto NR4 and NR7 Scanner: Narrow Range Days on USDT Pairs

The narrow range day

• Range = the day's high − low.
• NR7: the day's range is strictly the smallest of the last 7 days, the day itself included.
• NR4: the smallest of the last 4 days, but not of the last 7. A day gets only the tighter tag.

The pattern does not imply a direction. It says the market went quiet, not which way it will move next.

The follow-up

The day after an NR day, the page checks whether the pair broke out with participation:

• Triggered Up: the close is above the NR day's high and volume is above 1.3× the 20-day average.
• Triggered Down: the close is below the NR day's low on the same volume.

The follow-up tabs show yesterday's setups only and drop off after one day. The test is on the close: a day that pokes above the NR high and closes back inside is not a trigger.

What is different on crypto

• Seven days is one week. NR7 on crypto compares the day with the six before it, weekends included. A Sunday is often narrow simply because it is a Sunday.
• "Narrow" is relative. RUNEUSDT was NR4 on 2 November with a range of 17.1%: narrow for RUNE that week, wider than most NSE stocks move in a month. The Range % column and ATR % show the scale.
• A setup can appear only on the follow-up tab. The NR day's own list shows only pairs that passed the 0.8× volume rule that day. A quiet NR day often fails it, so its setup is missing from the NR4 / NR7 tabs. If the next day breaks out on volume, it appears under Triggered Up or Down anyway. BNBUSDT on 3 and 4 November is an example.

How these examples were worked out: signed-out visitors can open only the newest day on the page, so the earlier days below come from Unfluke's own scanner code run on Binance spot candles grouped into IST days. Unfluke's crypto archive is Binance data, and for 8 November 2026, the newest day the page showed when this was written, the two agree exactly. The page's own figures for the earlier days should be the same or very close.

LINKUSDT: NR7 on 3 November 2026

• 3 November: high 11.308, low 11.004, a range of 2.73% of the close. Range rank 1: the tightest of the seven days. LINK was 5.7% below its 20 EMA, in a downtrend.
• 4 November: LINK first traded down to 10.631, below the NR low, then rallied to 11.796 and closed at 11.565, above the NR high, on 1.46× volume. Triggered Up.
• 5 November: the market fell; LINK closed at 10.739, back below the NR low. By 8 November it was at 10.693.

The follow-up day broke both sides of the range. On a 24-hour market that is common: the price can break one side and then the other within the same day, and only the 23:59 IST close decides the tag.

BNBUSDT: a setup you could not see the day before

BNBUSDT's range on 3 November (703.30 to 691.66, 1.67%) was the narrowest of its week: an NR7. It did not appear on the NR7 tab, because only 7 pairs passed the volume rule that day and BNB was not one. On 4 November it closed at 718.39 on 1.32× volume, above the NR high, and appeared under Triggered Up. Like LINK, it had first dipped below the NR low (680.74). On 5 November it closed at 693.25, back inside the range.

23 August 2026: when the whole market is narrow

After three explosive days (BTC's ranges were 7.8%, 6.7% and 9.3% on 19, 20 and 21 August), Sunday 23 August was quiet. 21 of the 31 liquid pairs were NR4 that day. When most of the market is narrow on the same day, the narrowness belongs to the market, not to each coin, and the breakout to watch is BTC's. On 24 August BTCUSDT closed at 79,013.99, above its NR4 high of 77,765.80, on 1.96× volume, and went on to close at 86,289.88 on 22 September.

Three months of follow-ups

From 1 August to 1 November 2026 the page would have shown 65 follow-ups. Three days later, 33 had closed further in the breakout direction, and 25 had closed back through the NR level they broke at least once in those three days. That is close to a coin toss. The pattern finds the moment a quiet market wakes up; it does not, on its own, pick the direction that lasts.

1. Count the NR rows. One or two pairs narrow on a busy day are coin stories. A long list on the same day, especially a weekend, is the market pausing.
2. Mark the levels the night before. The NR high and low are the trigger levels. The page judges the breakout on the IST close; if you trade intraday, decide in advance whether you act on a break or on the close.
3. Use the trend filter. "Above 20 EMA" keeps setups in uptrends, "Below 20 EMA" in downtrends. A breakout in the direction of the trend is the more common study.
4. Look at the follow-up day's low and high. LINK and BNB both broke below before closing above. A trigger after a wide two-sided day is a weaker signal than one that went straight through.
5. Let the next day confirm. In November, both triggers were undone the following day as the market fell.
6. Place the stop inside the range. The opposite side of the NR day, or its midpoint for a tighter test. The narrow range is what makes the stop small.

Risk per trade - risk a small, fixed share of capital on any one idea. Crypto never closes, so a stop is the only exit while you sleep; with leverage, keep the liquidation price well beyond the stop. When selling options, prefer defined-risk structures (spreads, iron condors) over naked positions.

These are ideas to study, paper-trade and backtest, not recommendations or signals, and not a promise of any result. Every condition below can fail. Crypto trades around the clock and can move sharply at any hour; leverage and options can lose more than you expect, and past behaviour says nothing certain about the next session. Size, entries, exits and risk are your own decisions.

1. Trend-side breakout

• Setup: an NR7 with the trend filter on Above 20 EMA, and BTCUSDT also above its 20 EMA.
• Idea: study only the upside break, entered on a daily close above the NR high on volume above 1.3×.
• Invalidation: a daily close back below the NR low.

2. Market-wide contraction, trade the leader

• Setup: half or more of the liquid pairs NR4 or NR7 on the same day.
• Idea: treat BTCUSDT's (or ETHUSDT's) NR levels as the market's levels. Study entering altcoins only after BTC closes outside its range, in the same direction.

3. The failed breakout

• Setup: a Triggered Up (or Down) row whose next daily close is back inside the NR range.
• Idea: trapped breakout buyers can add to the move the other way. Study the opposite side, with the stop beyond the follow-up day's extreme.

Test before you trade - write the rules down exactly, test them on past data (see how to backtest an options strategy and the Option Simulator, which supports crypto), then paper-trade at least 20 occurrences before committing real money. Keep a journal of every trade, including the ones you skipped.

The tabs

• All - every NR4 and NR7 day today, NR7 first, tightest first.
• NR4 - narrowest of 4 days (and not of 7).
• NR7 - narrowest of 7 days.
• Triggered Up / Triggered Down - yesterday's NR day; today closed beyond its high or low on volume above 1.3×. Sorted by volume ratio.

The filters

• Trend context - Any, Above 20 EMA or Below 20 EMA.
• Date and Universe (All, Futures, Options) - for signed-in users.

The columns

• Range % - the NR day's (high − low) ÷ close.
• Range Rank - where the day's range sits among the last 7, 1 being the tightest.
• NR High, NR Low - the trigger levels.
• 20 EMA, ADX, ATR % - trend position, trend strength and normal daily movement.
• Vol ratio - the day's volume ÷ the 20 days before it.
• Tag - NR4 or NR7, and the follow-up direction.
• 5 Days, Chart - the last five candles, and the daily chart with the NR levels drawn in.

Which pairs are read

• Live USDT pairs in Unfluke's crypto archive: 33 were scanned on 8 November 2026, from BTCUSDT and ETHUSDT to small pairs such as SOLVUSDT and GALAUSDT. A pair whose feed has stopped for three days is no longer live, and one that traded under US$100,000 in the day is left out as untraded.
• Flat pairs are left out by behaviour, not by name. A pair whose average daily range over 20 days is under 0.25% is a stablecoin in practice, and no momentum measure means anything on it.
• Liquidity first: a 20-day average turnover above US$500,000 (the day itself included) and the day's volume above 0.8× the average of the 20 days before it.
• No circuit rule. Crypto has no price bands, so nothing is left out for hitting one.
• No sector column and no "Indices" universe. The universe box offers All, Futures and Options: the pairs that have a perpetual future, or options, in Unfluke's archive.

What to keep in mind

Weekends empty the lists. Crypto trades on Saturday and Sunday, but far fewer people trade. From August to early November 2026, BTCUSDT's weekend volume was typically about half its 20-day average (a median of 0.48×), so most pairs fail the 0.8× volume rule. Across those 100 days a median of 21 pairs passed on a weekday and 6.5 on a weekend; on Sunday 8 November none did, and every momentum list was empty. An empty weekend page is the rule doing its job, not a fault.

The daily bars are rolled up from Unfluke's one-minute spot archive (Binance data) into IST days, 00:00 to 23:59. Volume is the coin's quantity; turnover is price × volume, in USDT. RSI 14 and ADX 14 use Wilder's smoothing, ATR is 14 days, and the EMAs are on the close, from the same library as the RSI and ADX scans, so a value here matches the value on those pages.

• Days are calendar days. Crypto has no holidays, so "10 to 40 days" or "the last 7 sessions" counts Saturdays and Sundays too. Seven sessions on crypto is one week; on NSE it is about a week and a half.
• The newest day can be unfinished. The daily bars are topped up during the day, so until 23:59 IST the newest day's range and volume are partial. A partial day usually fails the 0.8× volume rule, and its range looks narrower than it will end up. For a finished reading, use the previous day (signed-in users can pick the date).
• One exchange, spot only. Perpetual futures often trade several times the spot volume and are not counted. A move driven by futures liquidations shows up here only through the spot buying or selling it set off.
• A stablecoin can slip through. The flat test averages the daily range over 20 days. A few one-minute spikes on a stablecoin can lift that average over 0.25%: USDCUSDT had spikes of 2.1% on 21 October and about 0.9% on 26 and 27 October, and from 5 November 2026 it passed the test. Its ADX then reads above 80 and it can rank on Momentum Rank. If you see USDCUSDT or another stablecoin on a list, ignore it.
