2. Components of Donchian Width Indicator:

• Upper Donchian Band = Highest high over N periods

• Lower Donchian Band = Lowest low over N periods

• Donchian Width Formula:

  Width=Upper Band−Lower Band\text{Width} = \text{Upper Band} - \text{Lower Band}

• Optional: Normalize as a percentage of price:

  Normalized Width=Upper−LowerMidpoint×100\text{Normalized Width} = \frac{\text{Upper} - \text{Lower}}{\text{Midpoint}} \times 100
