Developer:Toby Crabel (ORBP: Opening Range Breakout Preference); Richard D. Donchian (Price Channel Filter). Source: Crabel, T. (1990). Day Trading with Short Term Price Patterns and Opening Range Breakout. Greenville: Traders Press, Inc. Concept: Volatility expansion with a price channel filter. Research Goal: Performance verification of a trend filter and time exit. Specification: Table 1. Results: Figure 1-2. Trade Entry: ORBP with Price Channel Filter: A trade is taken at a predetermined amount above/below the open. The predetermined amount is called the stretch. Long Trades: In a bullish mode (defined by the Filter; Table 1), a buy stop is placed at [Open + Stretch]. Short Trades: In a bearish 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: 35 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 = 1;
UpperChannel(Filter_Look_Back) is the highest high over a period of Filter_Look_Back. LowerChannel(Filter_Look_Back) is the lowest low over a period of Filter_Look_Back. Long Trend Filter: If High[i] > UpperChannel[i − 1] then the trend is “long” (only long trades are accepted). Short Trend Filter: If Low[i] < LowerChannel[i − 1] then the trend is “short” (only short trades are accepted). Index: i ~ Current Bar.
Filter_Look_Back = [2, 100], Step = 2;
ORBP with Price Channel Filter: 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 bullish mode (defined by the Filter), a buy stop is placed at [Open + Stretch]. Short Trades: In a bearish mode, a sell stop is placed at [Open − Stretch].
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].
IV. Rating: ORBP with Price Channel Filter | Trading Strategy
(i) The trend filter defined by the variable “Filter_Look_Back” improves performance of the Opening Range Breakout (Figure 1-2); (ii) The longer holding period defined by the variable “Time_Index” is preferred (Figure 1-2); (iii) This test serves as the base case for the subsequent research of short-term patterns.
