## When to prefer this

Use this endpoint when you need a specific VWAP reversion strategy signal for BTC with actionable trade parameters (entry bias, SL, TP, hold time). Prefer this over the fused signal endpoint when you want the raw output of a single named strategy rather than a blended consensus signal.
