Kaufman Efficiency Ratio Metatrader 4 Forex Indicator Review

The Kaufman Efficiency Ratio (KER) is a popular technical analysis indicator used in the Forex market to measure the efficiency of price movements. Developed by Perry J. Kaufman, this indicator aims to identify trends and potential reversals by analyzing the ratio between the average change in price and the absolute deviation from that average over a given period.

Metatrader 4 (MT4), one of the most widely used trading platforms for Forex traders worldwide, offers various built-in indicators including KER. The combination of MT4’s advanced charting tools with KER can help traders make informed decisions about their trades based on trend strength or weakness.

This article will explore how KER works as an indicator within MT4, its benefits, drawbacks, and practical applications for Forex traders seeking to gain insights into efficient market movements.

Understanding The Kaufman Efficiency Ratio

The Kaufman Efficiency Ratio (KER) is a technical indicator developed by Perry J. Kaufman that measures the efficiency of price movements in financial markets. The ratio compares the net change in an asset’s prices over a given period to the sum of its positive and negative changes during that same interval, thereby providing traders with insights into market trends and volatility.

This calculation method allows for more accurate data analysis and helps investors make informed decisions. To calculate KER, one must first determine the average true range (ATR), which measures volatility by analyzing price fluctuations over time. Next, divide the net change in price by ATR to obtain a normalized value reflecting the degree to which recent price movement deviates from historical averages.

Finally, use this number to create an oscillator ranging between 0 and 1; values closer to 1 indicate more efficient market conditions while those nearer to zero suggest lower trading effectiveness. Historical analysis has shown that KER can be used effectively across various asset classes such as stocks, futures, currencies, and commodities.

By identifying periods of high or low efficiency within these markets, traders may adjust their strategies accordingly. For example, when KER is high it may suggest opportunities for long-term investments whereas low ratios could signal short-term trades based on quick gains before market inefficiency returns.

Overall, understanding how to interpret and apply KER correctly offers valuable insights into market trends that can help maximize returns while minimizing risk exposure.

Implementing Ker In Mt4

The Kaufman Efficiency Ratio (KER) is a popular technical indicator used in forex trading to measure the efficiency of price movements. KER calculation involves dividing the sum of positive changes by the sum of negative changes over a specified period and multiplying it by 100. The resulting value oscillates between zero and one, where values closer to one indicate more efficient price movement.

MT4 customization allows traders to add custom indicators like KER to their charts for better analysis and decision-making. To implement KER in MT4, traders need to:

  • Open the Navigator window
  • Select ‘Indicators’
  • Locate the KER indicator from the list or use an external source code file if unavailable.

Once added, they can customize its parameters such as time periods and colors for visual clarity.

In conclusion, implementing KER in MT4 can enhance a trader’s analytical capabilities and improve their chances of making profitable trades in forex markets. By calculating the ratio of positive and negative price changes over a set period, this indicator provides valuable insights into market dynamics that are otherwise difficult to discern. Moreover, with MT4 customization options available at their fingertips, traders can tailor KER settings to suit individual preferences and optimize its functionality further.

Practical Applications For Forex Traders

The Kaufman Efficiency Ratio (KER) is a technical indicator that has gained popularity among traders in the forex market. It was developed by Perry Kaufman to address the limitations of other indicators like moving averages, which tend to lag behind price movements.

The KER measures the ratio of the change in price over a fixed period to the sum of all price movements within that same period and produces an efficiency score between 0 and 1. Traders use this score to identify trends, reversals, and potential trade opportunities.

To calculate efficiency scores using KER, traders can choose any time frame from minutes to months depending on their trading strategy. A high-efficiency score indicates that most price movements were in one direction with minimal retracements or sideways movements. On the other hand, a low-efficiency score suggests frequent changes in price direction, indicating possible indecision or uncertainty among market participants.

Traders often compare KER with other technical indicators like Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), or Bollinger Bands to confirm signals or filter out false ones.

While there are no definite rules for interpreting KER values, some traders consider a reading above 0.5 as bullish and below 0.3 as bearish. However, it’s essential to remember that these levels may vary depending on market conditions and individual preferences.

Also, while KER alone can provide valuable insights into market sentiment and momentum strength, it’s always recommended to combine it with other fundamental and technical analysis tools before making trading decisions.

Examples of practical applications for calculating efficiency scores using KER:

  • Identifying trend reversals: If KER shows consistently decreasing efficiency scores while prices keep rising, it could indicate weakening momentum and signal an upcoming reversal.
  • Trading breakouts: When prices consolidate within a range but show sudden spikes outside that range accompanied by high-efficiency scores, traders might interpret it as a breakout and take positions accordingly.

Comparing KER with other technical indicators:

  • RSI: Both KER and RSI measure momentum, but while RSI compares the magnitude of price gains to losses, KER focuses on the efficiency of price movements. Combining both can help traders identify overbought/oversold conditions more accurately.
  • MACD: While both KER and MACD signal trend direction changes, MACD is a lagging indicator that uses moving averages, whereas KER is a leading indicator based on recent price activity. Traders might use MACD to confirm or refute signals provided by KER.

In summary, Kaufman Efficiency Ratio (KER) is an effective tool for forex traders to gauge market sentiment and momentum strength. By calculating efficiency scores using different time frames, traders can identify trends, reversals, or potential trade opportunities. Moreover, comparing KER with other technical indicators like RSI or MACD can provide additional confirmation or filtering of signals. However, like any other trading strategy or tool, it’s crucial to exercise caution and combine multiple sources of information before making decisions.


The Kaufman Efficiency Ratio (KER) is a technical indicator that was developed by Perry J. Kaufman to measure the efficiency of price movements in financial markets. It is calculated as the ratio between the net change in price over a certain period and the sum of all absolute price changes during that same time frame.

The KER can be used to identify trends, volatility, and potential trading opportunities. Implementing KER in MetaTrader 4 (MT4) involves adding it as a custom indicator using MQL programming language or downloading pre-made versions from various online resources. Once added, traders can use it in combination with other indicators to confirm signals and make more informed decisions.

Practical applications for Forex traders include identifying trend reversals, setting stop-loss orders based on volatility levels, and determining optimal entry and exit points for trades. Additionally, combining KER with other indicators such as moving averages or oscillators can provide further insight into market conditions and potential trade setups.

In conclusion, incorporating the Kaufman Efficiency Ratio into one’s trading strategy can offer valuable insights into market efficiency and assist in making informed trading decisions. With its ability to measure trends and volatility while providing clear buy/sell signals, this tool has become an essential part of many successful trader’s arsenal.

By utilizing MT4’s customization options, traders can easily add this powerful tool to their analysis toolkit today.
