Features:
Prior Day High and Low:
The script tracks and displays the previous trading day's high and low prices. These levels can serve as important areas of support or resistance, helping traders to make informed decisions about potential price reversals or breakouts.

Highest High and Lowest Low Over N Days:
This indicator also tracks and displays the highest high and lowest low over the last N days, where N is user-configurable. This allows traders to see broader trends in price action and identify key levels for potential trend changes.
