NR7 Strategy on Nifty:
The Narrowest Range in 7 Days Breakout Setup

What Is the NR7 Pattern?

NR7 stands for "Narrowest Range in 7 days." A day qualifies as NR7 when its trading range (High − Low) is the smallest of the last 7 trading sessions. On Nifty, this means the current session's range is tighter than every session in the past week.

NR7 is a volatility compression signal — the market is "coiling" before a directional move. Just as a compressed spring releases with force, a period of minimum volatility is followed by above-average volatility. The NR7 day itself is not the trade — the breakout the following session is.

The Logic Behind NR7

• Why 7 sessions? Seven trading sessions = one full week of price action. A 7-day range minimum means price has consolidated more tightly than at any point in the past week — a significant compression that statistically precedes large moves.
• Mean reversion of volatility: Markets alternate between periods of high and low volatility. After extended low-volatility compression (NR7), the market tends to return to average volatility — which means a larger-than-average range day follows.
• Institutional positioning: NR7 days often coincide with periods when large institutions are building positions quietly before a major move. The compression in range reflects controlled, deliberate trading rather than random noise.

Identifying NR7 on Nifty

To identify NR7 manually:

1. Calculate the range (High − Low) for the last 7 daily sessions
2. If today's range is smaller than all 6 previous sessions — it is an NR7 day
3. Note the NR7 day's High and Low — these become your breakout levels

In TradingView, you can add a custom script or manually compare ranges. Alternatively, look for days with very small daily candle bodies and wicks — NR7 days are visually obvious as the "shortest" candle in the last week.

Trading the NR7 Breakout on Nifty

• Setup: Identify an NR7 day on Nifty daily chart. Mark the NR7 day's High and Low.
• Entry — bullish breakout: Place a buy stop order 5 points above the NR7 day's High. This triggers when the next session breaks above the compression range.
• Entry — bearish breakdown: Place a sell stop order 5 points below the NR7 day's Low. Triggers on breakdown below the range.
• You can place both orders simultaneously (OCO — One Cancels Other) — whichever direction breaks out first triggers your entry, and the other order is cancelled.
• Stop loss: The opposite end of the NR7 range. If you are long above the High, stop is below the Low (or below the mid-point of the NR7 range for tighter risk).
• Target: The average range of the previous 7 sessions projected from the breakout point. If average range was 250 points and NR7 range was 80 points, target the 250-point move from the breakout level.

Filters to Improve NR7 Success Rate

• Daily trend direction: Trade only in the direction of the daily trend. If daily is bullish (HH-HL), trade only the bullish NR7 breakout above High. Skip the bearish breakdown side.
• After a news event: NR7 days often form the day before major events (RBI policy, Budget, US Fed). The breakout the next day can be explosive. Identify these and be ready.
• India VIX below 16: NR7 breakouts work best in low-to-normal volatility environments. When VIX is above 20, NR7 breakouts are less reliable — the market is already volatile and the "compression" signal is weaker.
• Avoid NR7 during market-wide ranges: If the Nifty daily chart has been ranging for 2+ weeks with no clear trend, NR7 breakouts frequently fail. The breakout needs broader trend momentum to sustain.
