Advanced Auto Fibonacci Retracement indicator that detects swing highs and lows, draws persistent Fibonacci levels between the most recent valid swing high/low pair, and and includes directional bias.
Automatically detects recent swing high/low based on user-defined strength.
Adjusts Fibonacci levels based on trend direction.
Persistent multi-bar lines using line objects.
Optional label display.
Clean, professional structure, ready for enhancements.

Swings are detected using ta.pivothigh / ta.pivotlow with adjustable strength.
When both a high and a low are found, the script calculates the range and draws 7 Fibonacci levels.
The script dynamically clears and redraws the lines and labels as the market updates.
Works in both uptrends and downtrends, with the levels adapting accordingly.
