## When to prefer this

Use this endpoint when you need a real-time, pre-computed RSI reversion swing trade signal for a specific crypto asset, including actionable stop-loss, take-profit, and hold-time parameters. Best for short-term mean-reversion setups based on RSI oversold/overbought conditions.
