Let’s face it—most traders struggle with one of two things: entering too late after the move has already started… or getting chopped up in sideways markets waiting for something to happen. That’s where the NR4 NR7 Indicator for MT4 steps in.

This custom MetaTrader 4 indicator is designed around a well-known concept from Linda Bradford Raschke and Toby Crabel—NR4 (Narrowest Range 4) and NR7 (Narrowest Range 7). It helps traders visually spot volatility compression zones so they can enter just before explosive breakouts happen.

And guess what? You can download this fully open-source version of the NR4 NR7 Indicator completely free right now.

Let’s dig into how it works, why it’s so effective, and how you can start using it in your daily trading flow.

Overview of the NR4 NR7 Indicator MT4

The NR4 NR7 Indicator MT4 is a powerful tool that highlights price bars with the narrowest trading range compared to the previous 4 or 7 bars, respectively. These candles indicate a tight compression phase in the market—just before a potential expansion in price volatility.

What is NR4?

“NR4” stands for Narrowest Range of the Last 4 Bars. The candle with the smallest range (High minus Low) compared to the last 3 candles gets flagged. It often signals low activity before a surge.

What is NR7?

Same idea, but with the last 7 bars. This makes it a slightly longer-term setup, and when both NR4 and NR7 occur at the same time—boom! You’ve got a high-probability volatility squeeze waiting to burst.

Purpose of the Indicator

Identify low volatility price compression phases

Time breakouts more accurately (before the move starts)

Filter out noise and avoid choppy conditions

Work with both trend and reversal strategies

How the Strategy Works

The NR4 NR7 strategy is a volatility breakout method. Here’s how it plays out in practice:

1. Spot Compression

The indicator tags an NR4 or NR7 candle. This bar has a lower range than its recent history, suggesting the market is “quiet.”

2. Wait for Confirmation

Next candle: you watch for a break above or below the NR4/NR7 candle’s high/low. That’s your trigger.

Buy breakout: if the next candle closes above the NR4/NR7 high

Sell breakout: if it breaks below the low

3. Set Your Orders

Entry: Place a buy stop just above the high or a sell stop just below the low

Stop Loss: A few pips beyond the opposite end of the candle

Take Profit: Use a 1:2 or 1:3 risk-to-reward setup or trail your stop

4. Enhance with Filters (Optional)

Use a moving average, RSI, or volume spike to confirm the setup and avoid false breakouts.
