Close vs SuperTrend % Diff

On Every Bar: SuperTrend and percent_diff are recalculated; the line plot updates with coloring.
On Visible Bars Only: High/low extremes and sums/counts accumulate via VC checks.
On Last Bar: Table refreshes with current stats, reflecting the visible view.
User Interaction: Zooming/panning triggers VC.barIsVisible() to recompute aggregates dynamically—no full history scan needed.
Edge Cases:

Empty visible range: High/low default to na; averages guarded against zero counts.
Division by zero in percent_diff: Unlikely, as st is ATR-based and rarely zero, but Pine handles na gracefully.
Performance: Efficient for long histories (e.g., daily charts over years) since stats are view-localized.



This indicator is useful for trend traders: Watch for percent_diff crossing zero for signals, and use the table to gauge visible volatility (e.g., if avg high > avg low in magnitude, bullish bias). Customize SuperTrend params (3,10) for different assets/timeframes. To extend, you could add alerts on threshold crosses or integrate dir for trend filters.
