Price Bands Script

This Pine Script indicator visually marks customizable percentage bands below the 52-week high of a security, even if historical data is limited.
• It calculates the highest price over the past 365 days or all available daily bars (whichever is less), ensuring compatibility with new or illiquid securities.
• The user can set two band levels as percentages below the 52-week high from the indicator settings.
• These bands are plotted as horizontal lines, and the area between them is shaded for easy visualization.
• The actual 52-week high is also plotted as a reference line.
• This helps traders identify meaningful pullback zones relative to the yearly high and adapt those levels to different strategies or market conditions
