James (Jim) M. Hurst bands form % of bands around the median calculated using the Hurst equation. External bands (called ExtremeBands) mean extreme overbought/oversold conditions. Internal bands mean potential price return points. They also act as dynamic support/resistance levels.
The indicator has seven adjustable parameters:
Calculation:
Center = MA[Period/2-1] HExtreme = Center * (1+Extreme value/100) LExtreme = Center * (1-Extreme value/100) HOuter = Center * (1+Outer value/100) LOuter = Center * (1-Outer value/100) HInner = Center * (1+Inner value/100) LInner = Center * (1-Inner value/100)
where:
MA = SMA(PRICE_MEDIAN, Period)
Hurst bands are often used together with Hurst oscillator, in particular, to search for divergences between bands and oscillator lines.
