Kaufman’s Adaptive Moving Average (KAMA)
Created by Perry Kaufman, KAMA is an volatility adaptive moving average of price over configurable lookback periods. [Discuss] 💬
// C# usage syntax
IEnumerable<KamaResult> results =
quotes.GetKama(erPeriods, fastPeriods, slowPeriods);
Parameters
erPeriods
int
- Number of Efficiency Ratio (volatility) periods (E
). Must be greater than 0. Default is 10.
fastPeriods
int
- Number of Fast EMA periods. Must be greater than 0. Default is 2.
slowPeriods
int
- Number of Slow EMA periods. Must be greater than fastPeriods
. Default is 30.
Historical quotes requirements
You must have at least 6×E
or E+100
periods of quotes
, whichever is more, to cover the warmup and convergence periods. Since this uses a smoothing technique, we recommend you use at least 10×E
data points prior to the intended usage date for better precision.
quotes
is a collection of generic TQuote
historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.
Response
IEnumerable<KamaResult>
- This method returns a time series of all available indicator values for the
quotes
provided. - It always returns the same number of elements as there are in the historical quotes.
- It does not return a single incremental indicator value.
- The first
E-1
periods will havenull
values since there’s not enough data to calculate.
⚞ Convergence warning: The first
10×E
periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

- Date from evaluated TQuote
ER
double
- Efficiency Ratio is the fractal efficiency of price changes

- Kaufman’s adaptive moving average
More about Efficiency Ratio: ER fluctuates between 0 and 1, but these extremes are the exception, not the norm. ER would be 1 if prices moved up or down consistently over the erPeriods
window. ER would be zero if prices are unchanged over the erPeriods
window.

Chaining
This indicator may be generated from any chain-enabled indicator or method.
// example
var results = quotes
.Use(CandlePart.HL2)
.GetKama(..);
Results can be further processed on Kama
with additional chain-enabled indicators.
// example
var results = quotes
.GetKama(..)
.GetRsi(..);
