Adaptive moving average trading system

Developed by Perry Kaufman, Kaufman's Adaptive Moving Average KAMA is a moving average designed to account for market noise or volatility. KAMA will closely follow prices when the price swings are relatively small and the noise is low. KAMA will adjust when the price swings widen and follow prices from a greater distance. This trend-following indicator can be used to identify the overall trend, time turning points and filter price movements.

There are several steps required to calculate Kaufman's Adaptive Moving Average. Let's first start with the settings recommended by Perry Kaufman, which are KAMA 10,2, Before calculating KAMA, we need to calculate the Efficiency Ratio ER and the Smoothing Constant SC. Breaking down the formula into bite size nuggets makes it easier to understand the methodology behind the indicator.

Note that ABS stands for Absolute Value. In statistical terms, the Efficiency Ratio tells us the fractal efficiency of price changes. ER fluctuates between 1 and 0, but these extremes are the exception, not the norm. ER would be 1 if prices moved up 10 consecutive periods or down 10 consecutive periods. ER would be zero if price is unchanged over the 10 periods. The smoothing constant uses the ER and two smoothing constants based on an exponential moving average.

As you may have noticed, the Smoothing Constant is using the smoothing constants for an exponential moving average in its formula. The Fastest SC is the smoothing constant for shorter EMA 2-periods.

The slowest SC is the smoothing constant for the slowest EMA periods. With the Efficiency Ratio ER and Smoothing Constant SC , we are now ready to calculate Kaufman's Adaptive Moving Average KAMA.

Since we need an initial value to start the calculation, the first KAMA is just a simple moving average. The following calculations are based on the formula below. The images below show a screen shot from an Excel spreadsheet used to calculate KAMA and the corresponding QQQ chart. Click here to download this spreadsheet example. Chartists can use KAMA like any other trend following indicator, such as a moving average.

Chartists can look for price crosses, directional changes and filtered signals. First, a cross above or below KAMA indicates directional changes in prices. As with any moving average, a simple crossover system will generate lots of signals and lots of whipsaws. Chartists can reduce whipsaws by applying a price or time filter to the crossovers. One might require price to hold the cross for set number of days or require the cross the exceed KAMA by set percentage.

Second, chartists can use the direction of KAMA to define the overall trend for a security. This may require a parameter adjustment to smooth the indicator further. Chartists can change the middle parameter, which is the fastest EMA constant, to smooth KAMA and look for directional changes. The trend is down as long as KAMA is falling and forging lower lows.

The trend is up as long as KAMA is rising and forging higher highs. The Kroger example below shows KAMA 10,5,30 with a steep uptrend from December to March and a less-steep uptrend from May to August.

And finally, chartists can combine signals and techniques. Chartists can use a longer-term KAMA to define the bigger trend and a shorter-term KAMA for trading signals. For example, KAMA 10,5,30 could be used as a trend filter and be deemed bullish when rising. Once bullish, chartists could then look for bullish crosses when price moves above KAMA 10,2, The example below shows MMM with a rising long-term KAMA and bullish crosses in December, January and February.

Long-term KAMA turned down in April and there were bearish crosses in May, June and July. KAMA can be found as an indicator overlay in the SharpCharts workbench. The default settings will automatically appear in the parameter box once it is selected and chartists can change these parameters to suit their analytical needs.

The first parameter is for the Efficiency Ratio and chartists should refrain from increasing this number.

Instead, chartists can decrease it to increase sensitivity. Chartists looking to smooth KAMA for longer-term trend analysis can increase the middle parameter incrementally. Even though the difference is just 3, KAMA 10,5,30 is significantly smoother than KAMA 10,2, This scan starts with stocks that average , shares daily volume and have an average closing price above An uptrend is present when trading above the longer-term KAMA 10,5, A buy signal materializes when price moves above the shorter-term KAMA 10,2, An downtrend is present when trading below the longer-term KAMA 10,5, A sell signal materializes when price moves below the shorter-term KAMA 10,2, For more details on the syntax to use for KAMA scans, please see our Scanning Indicator Reference in the Support Center.
