The Narrow Range (NR4, NR7) trading strategy is a breakout and reversal pattern that capitalizes on price breakouts following periods of consolidation characterized by narrow price ranges.
This strategy is based on the idea that after a period of tight price movement, a significant breakout is likely to occur in the direction of the breakout, leading to potential trading opportunities.
The term “NR” in “NR4” or “NR7” means “Narrow Range”.
The Narrow Range strategy finds its origins in the world of technical analysis and has been popularized by traders seeking to capture explosive price movements.
The NR4 and NR7 patterns are variations of this strategy that focus on specific time frames: the Narrow Range 4 (NR4) looks at the last four days’ price ranges, while the Narrow Range 7 (NR7) considers the last seven days.
Narrow Range Patterns was first coined in the book Day Trading With Short Term Price Patterns And Opening Range Breakout by Toby Crabel.
The book showcases an in-depth analysis of many theories and their subsequent patterns based on just Open, High, Low, Close of a said security and their statistical outcomes.
Despite being introduced in the 1990s, the NR4 and NR7 patterns continue to hold relevance in today’s dynamic trading environment.
The key concept underlying NR4 and NR7 patterns is the identification of days with exceptionally narrow price ranges. A narrow range indicates a period of consolidation where the market is “coiling” before making a potentially significant move. This can serve as a precursor to a breakout, as the market often builds up momentum during such periods.
NR7 is the term given to a day that has the daily range smallest of last 7 days including that day. Although NR Strategies started using prices of Daily Timeframe, The core theory is valid for all timeframes with more increasing uncertainty in smaller timeframes.
Note – Instead of referring to “day”, It is also referred as “bar”.
Similarly, In, NR4 Strategy, we try to identify stocks where the range is narrowing and the current bar’s range is the lowest amongst 4 bars ( i.e. 3 bars excluding the current bar).
So, by definition –
Criteria | NR4 | NR7 |
---|---|---|
Definition | A bar with the narrowest range of the last 4 bars. | A bar with the narrowest range of the last 7 bars. |
Significance | Often precedes a significant price move. | Indicates potential price volatility ahead. |
Timeframe | Considers the last 4 bars. | Considers the last 7 bars. |
Usage | Used to identify potential breakout or reversal setups. | Used to anticipate upcoming market volatility. |
Application | Commonly used in technical analysis and trading strategies. | Useful for traders seeking volatility-based opportunities. |
The NR4 and NR7 patterns can be applied to various markets, including stocks, forex, and commodities. Here’s how to use this strategy:
The NR4 and NR7 trading strategy offers several benefits, including the potential to capture strong trending moves after periods of consolidation. However, it’s important to consider the following points:
The market goes through contractions (i.e. daily trading range getting shorter and shorter) and expansions (i.e. daily trading range getting bigger) cycle. The author argues that after contraction, the probability of “breakouts” or expansions, occurring is higher.
The philosophy behind the pattern is similar to the Bollinger Band Squeeze: a volatility contraction is often followed by volatility expansion. In this case, Volatility is being quantified by “Range” of the prices.
The Narrow Range strategy is considered a time compression pattern due to the way it harnesses the concept of condensed price action within a narrow range. This compression signifies a temporary equilibrium between buying and selling forces, resulting in reduced volatility and limited price movement.
When such compression occurs, it’s analogous to winding a spring – the tighter the coil, the more energy it holds for an eventual release. In the context of trading, the narrow range acts as a pressure cooker!
As price is compressed within a smaller range, it represents a period of uncertainty and indecision among traders. However, markets are dynamic and ever-changing. The calm before the storm is often a precursor to a substantial price movement, as pent-up buying or selling interest seeks an outlet.
Thus, the narrow range strategy, as a time compression pattern, seeks to capitalize on these moments of compressed volatility, aiming to capture the ensuing trend that often follows such a release of energy.
