Kaufman Efficiency Ratio Stock Analysis & Kaufman Efficiency Ratio Trading Signals

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

The Kaufman Efficiency measures the ratio of the relative market speed in relation to volatility. The Kaufman efficiency is often used by Stock traders as a filter to help avoid trading when the stocks market is "choppy" or flat ranging markets. The indicator also helps to identify smoother Stock 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.

Kaufman Efficiency Ratio

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

Stock Trading Analysis & Generating Trading Signals

The Kaufman is used to generate stock signals as follows:

The smoother the manner in which the stocks 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 stocks market trend movements (ranging stock markets).

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

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

Bullish/Buy Trading Signal

Efficiency Ratio values above +30 indicate a smoother upward stocks trend.

Buy signal is generated above center-line mark.

Buy Trading Signal

Bearish/Sell Trading Signal

Efficiency Ratio values below -30 indicate a smoother downward stocks trend.

Sell Stock Signal is generated below zero center-line mark.

However, it is good you experiment with other values to determine the most appropriate levels for stock being traded and the value that is the best for your stock methodology that you're using.
