Developer:Toby Crabel (Bear Hook Pattern). Source: Crabel, T. (1990). Day Trading with Short Term Price Patterns and Opening Range Breakout. Greenville: Traders Press, Inc. Concept: Volatility expansion. Research Goal: Performance verification of the Bear Hook Pattern with the target exit and time exit. Specification: Table 1. Results: Figure 1-2. Trade Setup: Short Trades: The current day opens below the previous day’s low and closes above the previous day’s close with a narrowing range. Trade Entry: Opening Range Breakout (ORB): Short Trades: A trade is taken at a predetermined amount below the open. The predetermined amount is called the stretch. A sell stop is placed at [Open − Stretch]. Trade Exit: Table 1. Portfolio: 42 futures markets from four major market sectors (commodities, currencies, interest rates, and equity indexes). Data: 32 years since 1980. Testing Platform: MATLAB®.
II. Sensitivity Test
All 3-D charts are followed by 2-D contour charts for Profit Factor, Sharpe Ratio, Ulcer Performance Index, CAGR, Maximum Drawdown, Percent Profitable Trades, and Avg. Win / Avg. Loss Ratio. The final picture shows sensitivity of Equity Curve.
Noise: The difference between the open for each day and the closest extreme to the open on each day (Noise[i] = min(High[i] − Open[i], Open[i] − Low[i])). Average_Noise: The simple moving average of Noise over a period of Stretch_Length. Stretch[i] = Average_Noise[i] * Stretch_Multiple. Index: i ~ Current Bar.
Stretch_Length = 10; Stretch_Multiple = 2;
Short Trades: The current day opens below the previous day’s low and closes above the previous day’s close with a narrowing range.
Opening Range Breakout (ORB): Short Trades: A trade is taken at a predetermined amount below the open. The predetermined amount is called the stretch (defined above). A sell stop is placed at [Open − Stretch].
Time Exit: nth day at the close, n = Time_Index. Stretch Exit: Short Trades: A buy stop is placed at [Open + Stretch]. The value is calculated at the day of entry. Target Exit: Short Trades: A buy at the close is placed if Low ≤ [Entry − $Target]. $Target is the multiple of the initial risk per trade (defined by exits) and Target_Index. Stop Loss Exit: ATR(ATR_Length) is the Average True Range over a period of ATR_Length. ATR_Stop is a multiple of ATR(ATR_Length). Short Trades: A buy stop is placed at [Entry + ATR(ATR_Length) * ATR_Stop].
