Kaufman Efficiency Ratio

Exported using NT Version 7.0.1000.5

The Kaufman Eifficiency Ratio is also know as Fractal Efficiency. It can be used as a filter to differentiate between trending conditions and sideways markets.

The efficiency ratio compares the absolute amount of the n-period momentum to the sum of the absolute amounts of the last n close-to-close changes. If all close-to-close changes pointed in the same direction - meaning either n consecutive upcloses or n consecutive downcloses - the fractal efficiency will take the value 100. This is an indication for a strong trend. If the n-period momentum takes the value 0, the fractal efficiency becomes 0 as well, indicating chop.

The fractal efficiency is used by the Kaufman Adaptive Moving Average to identify chop periods.

This version of the Kaufman Efficiency Ratio has a few additional options:

Chopline: I have added a chopline, which depends on the period of the Kaufman Efficiency Ratio. The formula for the chopline is 100/Sqrt(period).

Signalline: I have added a signalline by using a Hull Moving Average(HMA). The market starts trending, when the Kaufman Efficiency Ratio has crossed both the signalline and the chopline from below.

Classic/Balanded: The indicator allows for two different ways of calculating the Kaufman Efficiency Ratio. The 'Classic' option uses the original formula of Perry Kaufman. The 'Balanced' option replaces the absolute amount of the n-period momentum with the absolute amount of the n-period balanced momentum, which is based on a triangular moving average.

Update June 22, 2013: Minor modification to make indicator compatible with indicators/strategies running in COBC = false.

Vertical Horizontal Filter

The VHF indicator can be a useful tool as it attempts to measure the �trendiness� of a market. It reveals the strength of a trend, not the trend direction. This filter compares the sum of one-day price changes within a specific time period to the range between the high and low prices over the specified period. The VHF values help identify whether prices are in a trending phase as well as the degree or strength of a trend, where the trader should use trend-following indicators, or if the prices are in a trading range market, a case where congestion-phase indicators (such as
oscillators which work well in trading range markets) should be used.

In theory, the VHF indicator can be used in the following three ways:

1. In determining whether a particular market condition is trending or is in a congestion/non-trending phase: A rising VHF line indicates a developing trend; a falling VHF line indicates prices may be entering a trading range market.

2. To determine the degree or strength of a trend: The higher the VHF line, the higher the degree of trending. A falling line indicates a trend is weak.

3. The use of the VHF as a contrarian indicator: Relatively low VHF values can indicate that prices can be expected to break out of the congestion phase and start trending. On the other hand, relatively high VHF values indicate that a trending phase may be coming to a close and that the market is getting ready to enter a congestion phase.
