Volatility indicator based on the article 10 Selling Tips by Thomas Bulkowski.

It has two configurable parameters:

  • Period - calculation period
  • Multiplier - ratio of the line deviation from the price

Calculation:

VSO = Multiplier * Avg / Close

where:

Avg = SMA(High,Period) - SMA(Low,Period)

It can be used with the Volatility Stop indicator.
