## What Is The Hurst Exponent

The Hurst exponent is used as a measure of long-term memory of time series. It relates to the autocorrelations of the time series and the rate at which these decrease as the lag between pairs of values increases. It tells you whether a series is

• Geometric random walk (H=0.5)
• Mean-reverting series (H<0.5)
• Trending Series (H>0.5)

If H decreases towards zero, the price series may be more mean-reverting and if it increases more towards one, the price series may be more trending.

## Hurst Exponent Indicator

It is an Oscillator indicator,  used as a measure of long-term memory of time series. It is referred to as the “index of dependence” or “index of long-range dependence”. ‘H’ quantifies the relative tendency of a time series either to regress strongly to the mean or to cluster in a direction.

## How to calculate the Hurst Exponent

‘H’ is nothing but the slope of the plot of each range’s log(R/S) versus each range’s log(size).

Here log(R/S) is the dependent or the y variable and log(size) is the independent or the x variable

## Why use the Hurst Exponent

The Hurst exponent is used as a measure of long-term memory of time series. It quantifies the relative tendency of a time series either to regress strongly to the mean or to cluster in a direction.

## How to Use The Hurst Exponent

Bullish Scenario:- If the Hurst value is more than 0.5 then it would indicate a persistent time series (roughly translates to a trending market).

Bearish Scenario:- If the Hurst Value is less than 0.5 then it can be considered as an anti-persistent time series (roughly translates to sideways market).
