1. Added band creation: - Create horizontal price lines for RSI overbought/oversold bands - Use createPriceLine() on the RSI series after it's created - Create lines at indicator.params.overbought and indicator.params.oversold levels - Store band references to prevent creating duplicate lines 2. Fixed line width priority: - Changed from 'indicator.params._lineWidth || plot.width || lineWidth' - To 'plot.width || indicator.params._lineWidth || lineWidth' - This ensures RSI bands use fixed 1px width from plot.width metadata - User can still adjust line width for other indicators Result: RSI bands now visible as dashed lines at 70/30 levels
