Mastering the Toby Crabel 2-Bar NR Pattern for Intraday Trading

The Foundation of Volatility Contraction

The 2-Bar Narrow Range (NR) pattern, a cornerstone of Toby Crabel's short-term trading methodologies, identifies periods of significant volatility contraction. These periods often precede sharp price movements, offering a low-risk entry for astute traders. The pattern itself is simple: it is the narrowest price range from high to low of any two-day period compared to the preceding 20 market days. This compression in price action signals a market in equilibrium, gathering energy for its next directional move.

Identifying the 2-Bar NR Pattern

To identify a 2-Bar NR pattern, a trader must meticulously track the daily high-low ranges. The process involves comparing the sum of the current and previous day's range to the corresponding two-day ranges over the past 20 trading sessions. For example, on a given day, you would calculate the range of day 0 and day -1. Then, you would compare this to the ranges of day -1 and day -2, day -2 and day -3, and so on, up to day -19 and day -20. The day the two-bar range is the narrowest of the lookback period is the 2-Bar NR day.

Entry and Exit Rules

Crabel's approach to trading the 2-Bar NR pattern is systematic. The entry is triggered by an Opening Range Breakout (ORB) on the day following the pattern's formation. A "stretch" value is calculated, which is a multiple of the average noise of the market. The stretch is typically twice the 10-day simple moving average of the minimum of (High - Open) and (Open - Low). A buy stop is placed at the open plus the stretch, and a sell stop is placed at the open minus the stretch. The first stop triggered initiates the trade.

Exits are just as important. A time-based exit can be employed, closing the position at the end of the trading day. A stretch-based exit would be the opposite of the entry signal. For instance, if a long trade is initiated, a sell stop is placed at the open minus the stretch. A target exit can be set at a multiple of the initial risk, while a stop-loss exit can be placed at a multiple of the Average True Range (ATR) below the entry price for a long position.

Real-World Application: SPY

Consider a hypothetical 2-Bar NR pattern on the SPDR S&P 500 ETF (SPY). After identifying the pattern, a trader would calculate the stretch based on the 10-day average noise. Let's assume the open on the breakout day is $450 and the stretch is $1.50. A buy stop would be placed at $451.50 and a sell stop at $448.50. If the price rallies and triggers the buy stop, the trader is long SPY. A stop loss could be placed at a 2x ATR multiple below the entry, and a profit target could be set at a 3:1 risk/reward ratio. The position would be closed at the end of the day if neither the stop loss nor the profit target is hit.
