Kaufman Efficiency Ratio MT4 Indicator Signals

Developed by Perry Kaufman. Described in his book entitled "New Systems and Techniques".

The Kaufman Efficiency measures the ratio of the relative market speed in relation to volatility. Kaufman efficiency is often used by traders as a filter to help avoid trading when the market is "choppy" or flat ranging markets. MetaTrader 4 Indicator also helps to identify smoother market trends. This is an MT4 Indicator that oscillates between +100 and -100, where zero is the center point. +100 is upwards trending market & -100 is downwards trending markets.

Kaufman Efficiency Ratio

The Efficiency MT4 Indicator is calculated by dividing the net change in the price movement over an n number of periods by the sum of all the bar-to-bar price changes taken as a absolute values over these same n periods.

MetaTrader 4 Indicator and How to Generate Trade Signals

The Kaufman is used to generate trading signals as follows:

The smoother the manner in which the market is trending then the greater the Efficiency Ratio shown by the MT4 Indicator. Efficiency Ratio value readings of around zero indicate a lot of inefficiency or "choppiness" in the market trend movements (ranging markets).

• If the Efficiency Ratio shows a reading of +100 for a currency pair, then that forex pair is trending upwards with perfect efficiency.
• If the Efficiency Ratio shows a reading of -100 for a currency pair, then that currency is trending downwards with perfect efficiency.

However, it's almost impossible for a market trend to have a perfect efficiency ratio since any retracement movement against the current trend direction during the time period being used to calculate the MT4 Indicator would decrease the efficiency ratio.

Bullish/Buy Signal

Efficiency Ratio values above +30 indicate a smoother uptrend.

Buy signal is generated above center-line mark.

Buy Signal

Bearish/Sell Signal

Efficiency Ratio values below -30 indicate a smoother downtrend.

Sell Signal is generated below zero center-line mark.

Sell Signal

However, it is good you experiment with other values to determine the most appropriate levels for the forex pair being traded & the value that is the best for your technique that you are using.
