The atr endpoint returns the ATR (Wilder's smoothing), its value as a percent of price and the true-range series; the stops endpoint returns ATR-based stop levels — the Chandelier Exit for long and short and an ATR trailing stop from an entry price; the keltner endpoint returns the Keltner Channel (EMA mid-line with ATR bands). A volatility-and-stops engine that needs the full high/low/close, distinct from closes-only indicator tools and single-coin volatility feeds. Computed locally, nothing stored — works for forex, stocks, crypto or commodities.",
