Introduction
Kaufman’s Adaptive Moving Average (KAMA) is a technical analysis indicator developed by Perry J. Kaufman in 1998. Unlike traditional moving averages such as the Simple Moving Average (SMA) or Exponential Moving Average (EMA), KAMA adapts to market conditions by adjusting its sensitivity based on price volatility. This adaptability makes KAMA particularly effective for filtering out market noise—temporary price fluctuations—and identifying true trends in financial markets like stocks, forex, and futures.
Why Use KAMA?
Traditional moving averages use fixed parameters, which can lead to false signals in volatile or choppy markets. KAMA, however, dynamically adjusts its smoothing factor, becoming more responsive during trending markets and less reactive in ranging markets. This reduces whipsaws (false signals) and provides traders with a clearer view of market direction, making it a valuable tool for technical analysis.
Calculation
Calculating KAMA involves three key steps, typically using the standard settings of KAMA(10,2,30). Below is a step-by-step explanation:
- Efficiency Ratio (ER): The ER measures the directional movement of the price over a specified period, usually 10 periods. It is calculated as:
- Smoothing Constant (SC): The SC determines how much weight is given to the current price and is derived from the ER. It is calculated as:
- Fast alpha = \( \frac{2}{2 + 1} = \frac{2}{3} \approx 0.6667 \)
- Slow alpha = \( \frac{2}{30 + 1} = \frac{2}{31} \approx 0.0645 \)
- KAMA: The KAMA is calculated iteratively using the formula:
These calculations allow KAMA to adapt dynamically to market volatility, making it more responsive during trends and smoother during consolidation.
Most trading platforms, such as TradingView, automatically compute KAMA, so traders rarely need to perform these calculations manually.
Example
To illustrate how KAMA works, consider a simplified example with 10 days of closing prices: 50, 51, 52, 53, 54, 55, 56, 57, 58, 59.
- Step 1: Calculate ER
- Step 2: Calculate SC
- Step 3: Calculate KAMA
This example simplifies the process to demonstrate KAMA’s mechanics. In real-world trading, KAMA is calculated continuously for each period, and platforms like TradingView or MetaTrader handle these computations automatically.

Use Cases
KAMA is a versatile indicator with several applications in technical analysis and trading. Below are some common use cases:
- Trend Identification: KAMA helps determine the overall market trend. Prices above KAMA suggest an uptrend, while prices below indicate a downtrend. This is useful for trend-following strategies.
- Trading Signals: Price crossovers with KAMA can generate buy or sell signals. For example, a price crossing above KAMA may signal a buy, while crossing below may signal a sell. These signals should be confirmed with other indicators to avoid false positives.
- Filtering Noise: KAMA’s adaptive nature filters out minor price fluctuations, providing a clearer view of the market’s direction, especially in volatile conditions.
- Trend Reversals: Using two KAMA lines with different settings (e.g., fast and slow periods), traders can spot potential trend reversals when the fast KAMA crosses the slow KAMA.
- Support and Resistance Confirmation: KAMA can be combined with price action analysis to confirm support and resistance levels. For instance, if the price bounces off the KAMA line at a support level, it may indicate stronger support.
These use cases make KAMA suitable for both trend-following and mean-reversion strategies, depending on the trader’s approach.
Comparison with Other Moving Averages
To understand KAMA’s unique features, it’s helpful to compare it with other moving averages:
Indicator | Description | Strengths | Weaknesses |
---|---|---|---|
Simple Moving Average (SMA) | Averages prices equally over a fixed period. | Simple to calculate and understand. | Lags in trending markets, prone to false signals. |
Exponential Moving Average (EMA) | Gives more weight to recent prices. | More responsive than SMA. | Fixed smoothing factor, still generates false signals in choppy markets. |
Kaufman’s Adaptive Moving Average (KAMA) | Adjusts smoothing based on market volatility. | Adapts to market conditions, reduces false signals. | Complex calculation, requires software for practical use. |
KAMA’s ability to adjust its sensitivity makes it a more dynamic tool, potentially offering better trend identification and fewer false signals than SMA or EMA.
Conclusion
Kaufman’s Adaptive Moving Average (KAMA) is a powerful and flexible tool for technical analysts and traders. By adapting to market volatility, it provides a more accurate representation of price trends compared to traditional moving averages. While its calculation is complex, modern trading platforms like TradingView or MetaTrader offer KAMA as a built-in indicator, making it accessible to traders of all levels.
Traders are encouraged to experiment with different KAMA settings (e.g., adjusting the ER period or fast/slow alpha values) and combine KAMA with other indicators, such as oscillators or volume analysis, to develop robust trading strategies.
