# Kaufman Adaptive Moving Average | Trading Strategy (Setup & Filter)

## I. Trading Strategy

**Developer:** Perry Kaufman (Kaufman Adaptive Moving Average – KAMA). **Source:** Kaufman, P. J. (1995). *Smarter Trading. Improving Performance in Changing Markets.* New York: McGraw-Hill, Inc. **Concept:** Trading strategy based on an adaptive noise filter. **Research Goal:** Performance verification of the setup and filter. **Specification:** Table 1. **Results:** Figure 1-2. **Trade Setup:** Long Trades: The Adaptive Moving Average (AMA) turns up. Short Trades: The Adaptive Moving Average turns down. **Note:** The AMA trendline appears to stop when markets have no direction. When markets trend, the AMA trendline catches up. **Trade Entry:** Long Trades: A buy at the close is placed after a bullish setup. Short Trades: A sell at the close is placed after a bearish setup. **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: | AMA(ER_Length) is the Adaptive Moving Average over a period of ER_Length. ER_Length is a look-back period of the Efficiency Ratio (ER). ER[i] = abs(Direction[i] / Volatility[i]), where “abs” is the absolute value, Direction[i] = Close[i] − Close[i − ER_Length], Volatility[i] = ∑(abs(DeltaClose[i]), ER_Length), where “∑” is the sum over a period of ER_Length, DeltaClose[i] = Close[i] − Close[i − 1]. FastMA_Length is a period of the fast moving average. SlowMA_Length is a period of the slow moving average. AMA[i] = AMA[i − 1] + c[i]*(Close[i] − AMA[i − 1]), where c[i] = (ER[i]*(Fast − Slow) + Slow)^2, Fast = 2/(FastMA_Length + 1), Slow = 2/(SlowMA_Length + 1). Index: i ~ Current Bar. | ER_Length = [2, 100], Step = 2; FastMA_Length = 2; SlowMA_Length = 30; |

Setup: | Long Trades: If AMA[i] > AMA[i − 1] & AMA[i − 1] < AMA[i − 2] then MinAMA = AMA[i − 1]; (Adaptive Moving Average turns up with a pivot at MinAMA). Short Trades: AMA[i] < AMA[i − 1] & AMA[i − 1] > AMA[i − 2] then MaxAMA = AMA[i − 1]; (Adaptive Moving Average turns down with a pivot at MaxAMA). Index: i ~ Current Bar. | |

Filter: | Filter[i] = Filter_Index * Std_Dev(AMA[i] − AMA[i − 1], N), where Std_Dev is the standard deviation of series over N periods. N = 20 (default value). Index: i ~ Current Bar. | Filter_Index = [0.0, 1.0], Step = 0.02; N = 20; |

Entry: | Long Trades: A buy at the close is placed when AMA[i] > AMA[i − 1] & (AMA[i] − MinAMA) > Filter[i]. Short Trades: A sell at the close is placed when AMA[i] < AMA[i − 1] & (MaxAMA − AMA[i]) > Filter[i]. Index: i ~ Current Bar. | |

Exit: | 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]. | ATR_Length = 20; ATR_Stop = 6; |

Sensitivity Test: | ER_Length = [2, 100], Step = 2 Filter_Index = [0.0, 1.0], Step = 0.02 | |

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) |
