Description
Kaufman Adaptive Moving Average
Syntax
KAMA(expr, erlen, fastest, slowest)
Parameters
expr  data series formula
erlen  lookback length for the Efficiency Ratio calculation used to adapt the EMA length
fastest  shortest EMA equivalent lookback period
slowest  longest EMA equivalent lookback period
Notes
KAMA is a kind of exponential moving average which adapts its weighting factor (often mistaken for a lookback length) at each bar of its calculation by computing the Kaufman Efficiency Ratio and using that to determine that bar's weighting.
The most common parameters are KAMA(expr, 10, 2, 30).
See stockcharts.com for further details.
This function supports onepass calculation when used in the Data Section with nonvariable length parameters.
