RSI (Relative Strength Index)
Daily Relative Strength Index — a momentum oscillator bounded 0–100 that measures the speed and magnitude of recent price moves. Above 70 is conventionally overbought, below 30 oversold. Windows: 7, 14, 21, 28 days (default 14) — the 21- and 28-day windows require the Starter plan or higher. Young coins return leading warm-up nulls.
