I. Trading Strategy

Developer: Toby Crabel (ORBP: Opening Range Breakout Preference). Source: Crabel, T. (1990). Day Trading with Short Term Price Patterns and Opening Range Breakout. Greenville: Traders Press, Inc. Concept: Volatility expansion with a counter-trend bias. Research Goal: Performance verification of the counter-trend filter and time exit. Specification: Table 1. Results: Figure 1-2. Trade Setup: N/A. Trade Entry: ORBP Counter-Trend: A trade is taken at a predetermined amount above/below the open. The predetermined amount is called the stretch. Long Trades: In a bearish mode (defined by the Filter; Table 1), a buy stop is placed at [Open + Stretch]. Short Trades: In a bullish mode, 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®.

STRATEGY	SPECIFICATION	PARAMETERS
Auxiliary Variables:	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;
Setup:	N/A
Filter:	Long Trades: Close[i − 1] < Close[i − Trend_Index]. Short Trades: Close[i − 1] > Close[i − Trend_Index]. Index: i ~ Current Bar.	Trend_Index = [2, 80], Step = 2;
Entry:	ORBP Counter-Trend: A trade is taken at a predetermined amount above/below the open. The predetermined amount is called the stretch (defined above). Long Trades: In a bearish mode (defined by the Filter), a buy stop is placed at [Open + Stretch]. Short Trades: In a bullish mode, a sell stop is placed at [Open − Stretch].
Exit:	Time Exit: nth day at the close, n = Time_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). Long Trades: A sell stop is placed at [Entry − ATR(ATR_Length) * ATR_Stop]. Short Trades: A buy stop is placed at [Entry + ATR(ATR_Length) * ATR_Stop].	Time_Index = [1, 40], Step = 1; ATR_Length = 20; ATR_Stop = 6;
Sensitivity Test:	Trend_Index = [2, 80], Step = 2 Time_Index = [1, 40], Step = 1
Position Sizing:	Initial_Capital = $1,000,000 Fixed_Fractional = 1% Portfolio = 42 US Futures ATR_Stop = 6 (ATR ~ Average True Range) ATR_Length = 20
Data:	42 futures markets; 32 years (1980/01/01−2011/12/31)
