The NR4 (Narrow Range 4) Inside Bar is an effective trading strategy used by Forex traders to identify potential trend reversals and breakouts. This strategy is based on identifying a specific candlestick pattern that indicates a contraction in price range compared to the previous three candles, followed by a small candle completely engulfed within the high-to-low range of the fourth candle.
Overview of NR4 Inside Bar

- Narrow Range 4 (NR4): The NR4 pattern occurs when the range of the fourth candle is the narrowest among the last four candles on the chart. This means that the fourth candle’s high-to-low price range is smaller than the three preceding candles.
- Interpretation: The NR4 Inside Bar pattern suggests that the market is experiencing a period of consolidation and indecision. It signals a potential breakout or reversal in the current trend, as traders anticipate the next move in the market.
- Trading Approach: Traders employing the NR4 Inside Bar strategy often wait for a breakout of the high or low of the NR4 candle before taking a position. A bullish breakout occurs when the price moves above the NR4 candle’s high, while a bearish breakout happens when the price drops below the NR4 candle’s low. In some cases, traders may wait for confirmation from subsequent price action before entering a trade.
- Timeframe: The NR4 Inside Bar strategy can be applied to various timeframes, ranging from short-term to long-term charts, depending on a trader’s preferred trading style.
Understanding the NR4 Pattern
The first step in using the NR4 Inside Bar strategy is to identify the NR4 pattern. NR4 stands for “Narrow Range 4,” which means that the range of the fourth candle in a sequence is the narrowest among the last four candles on the chart. The range refers to the difference between the highest and lowest price levels of a candle.
For example, let’s say we have four consecutive candles with the following price ranges:
Candle 1: High – 1.3000, Low – 1.2900 (Range = 100 pips)
Candle 2: High – 1.3050, Low – 1.2950 (Range = 100 pips)
Candle 3: High – 1.3100, Low – 1.3000 (Range = 100 pips)
Candle 4: High – 1.3030, Low – 1.3005 (Range = 25 pips)
In this example, Candle 4 has the narrowest range (25 pips) compared to the previous three candles, making it an NR4 candle.
The Inside Bar
Within the NR4 candle (Candle 4), there exists a smaller candle that is entirely engulfed within the high-to-low range of Candle 4. This smaller candle is known as the “inside bar.” An inside bar is a candlestick pattern where the entire price range of the candle is contained within the range of the preceding candle.
Interpretation of the NR4 Inside Bar Pattern
The NR4 Inside Bar pattern indicates a period of consolidation and indecision in the market. Traders often interpret this as a potential sign of a breakout or trend reversal. The tightening price range suggests that market participants are undecided about the next direction, and when a breakout occurs, it may trigger significant price movements.
Implementing the Strategy
To use the NR4 Inside Bar strategy for Forex trading, traders typically wait for a breakout of the high or low of the NR4 candle before taking a position. Here’s how it works:
- Bullish Breakout: If the price moves above the high of the NR4 candle, it signals a potential bullish breakout. Traders might consider entering a long position, expecting the price to rise further.
- Bearish Breakout: If the price drops below the low of the NR4 candle, it signals a potential bearish breakout. Traders might consider entering a short position, expecting the price to decline further.
Timeframe and Application
The NR4 Inside Bar strategy can be applied to various timeframes, depending on a trader’s preferred trading style. Short-term traders might focus on lower timeframes (e.g., 15-minute or 1-hour charts) to try to identify quick breakouts, while long-term traders might use higher timeframes (e.g., daily or weekly charts) to spot more significant trend reversals.
NR4 Inside Bar Pros & Cons
Pros

- Limited Frequency: The NR4 Inside Bar pattern may not appear frequently on the charts, especially on higher timeframes. Traders might need to exercise patience and wait for suitable setups.

- Whipsaw Markets: In choppy or ranging markets, the NR4 Inside Bar signals may lead to false breakouts and provide unclear direction, resulting in potential losses.
- Subject to Market Sentiment: The NR4 Inside Bar strategy relies on market sentiment and participation. In thin or illiquid markets, the patterns may not hold as much significance.

The strengths of the NR4 Inside Bar strategy lie in its simplicity, clear entry and exit signals, and risk-reward ratio.
