Kaufman Efficiency Ratio Stock Indices Technical Analysis and Kaufman Efficiency Ratio Stock Indices Signals


Developed by Perry Kaufman. Described in his book entitled “New Trading Systems and Methods”.


The Kaufman Efficiency is a measures the ratio of the relative market speed in relation to the volatility. The Kaufman efficiency is often used by Stock Indices traders as a filter to help avoid trading when the stock indices market is “choppy” or flat ranging markets. The indicator also helps to identify smoother Stock Indices Trading market trends. This is an oscillator indicator that oscillates between +100 and -100, where zero is the center point. +100 is upward trending market and -100 is downwards trending markets.

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



Stock Indices Technical Analysis and Generating Stock Indices Signals


The Kaufman is used to generate stock indices signals as follows:


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



  • If the Efficiency Ratio shows a reading of +100 for a stock indices instrument, then that stock indices instrument is trending upwards with perfect efficiency.
  • If the Efficiency Ratio shows a reading of -100 for a stock indices instrument, then that stock index price is trending downwards with perfect efficiency.


However, it is almost impossible for a market stock indices trend to have a perfect efficiency ratio since any retracement movement against the current stock indices trend direction during the time period being used to calculate the indicator would decrease the efficiency ratio.
