RVI with SMA Smoothing and Divergence Signals

This script enhances the Relative Volatility Index (RVI)—originally introduced by Donald Dorsey in 1993—by integrating three complementary analytical features:

1. SMA-based smoothing of the RVI line to reduce noise and clarify the underlying volatility momentum trend.
2. Automated detection of regular and hidden divergences between price action (highs/lows) and RVI pivots, using robust `ta.pivotlow` and `ta.pivothigh` logic with configurable lookback and search ranges.
3. Visual labels ("R" for regular, "H" for hidden) and color-coded pivot markers to help traders quickly identify potential reversal or continuation zones.

Unlike basic RVI implementations, this version is designed to highlight momentum-price decoupling, a key concept in technical analysis. The divergence engine is synchronized with RVI’s unique 0–100 scale and volatility-based calculation, ensuring signals are contextually relevant—not generic overlays.

How it works:
- RVI is computed using standard deviation of directional price changes, normalized to 0–100.
- A user-defined SMA (default: 14 periods) smooths the RVI for trend clarity.
- Divergences are confirmed only when both a valid price pivot and a corresponding RVI pivot occur within a configurable bar range (default: 5–60 bars).
- Hidden bearish divergences are disabled by default to reduce noise on short-term charts.

Suggested use:
- Regular bullish divergences near the 20 (oversold) level may signal exhaustion of a downtrend.
- Regular bearish divergences above 80 (overbought) can warn of upward momentum loss.
- Combine with price structure (support/resistance) for higher-probability setups.

This script is **not a simple mashup**: the integration of divergence logic with RVI’s volatility-based nature, parameterized sensitivity controls, and clean visualization provides a cohesive analytical tool not found in standard indicators.
