The DHLBO (Dynamic High/Low Band Overlay) indicator shows on the price chart two bands calculated based on the range Highs/Lows.

It has two input parameters:

  • Period;
  • Expansion.

Calculations:

Up band = Min+(Max-Min)*Expansion
Dn band = Max-(Max-Min)*Expansion

where:

  • Min, Max - the highest and lowest prices within the Period interval.
