The Percentile indicator calculates a dynamic percentile value of recent price data, offering a distribution‑based alternative to traditional moving averages. Instead of smoothing prices with arithmetic means, it sorts the last N bars and selects the value at a chosen percentile.

• Flexible Percentile Input (0–100):
  Choose any percentile — from median (50) for robust central tendency, to quartiles (25/75) for volatility envelopes, or extremes (near 0/100) to capture distribution tails.
• Adaptive Circular Buffer:
  Efficient rolling window stores recent prices, ensuring accurate percentile calculations without lagging historical data.
• Change Tolerance Filter:
  Avoids redundant recalculations when price changes are negligible, improving performance and chart clarity.
• Customizable Period:
  Define the lookback length to adapt the indicator to intraday scalping or longer‑term swing trading.

🔎 Why Use It?

• Provides a non‑linear smoothing method that adapts to market distributions.
• Reduces the influence of outliers compared to SMA/EMA.
• Can be extended into percentile bands (e.g., 25th–75th range) for dynamic support/resistance zones.
• Works on any source (close, open, high, low, or custom inputs).

⚡ Notes

• Best used with moderate window lengths (20–100 bars).
• Percentile choice determines sensitivity: median for stability, quartiles for volatility, extremes for breakout detection.
• Lightweight implementation with circular buffer ensures efficient performance.
