bityield — Options Volatility Skill (BitYield Framework)

An OpenClaw agent skill for analyzing and trading options volatility using the **BitYield** three-dimensional framework. Covers BTC options on Deribit and equity options (NVDA, AAPL, TSLA, META, AMZN, GOOGL, MSFT, etc.).

What This Skill Does

• Real-time Vol Surface analysis: Fetch ATM IV, 25d Risk Reversal, 25d Butterfly across expiries
• Multi-ticker skew scanner: Rank equity options by skew and kurtosis premium simultaneously
• Position calculator: Entry price, net premium, Greeks (Delta/Gamma/Vega/Theta/Vanna), Delta hedge ratio, and P&L scenarios at expiry
• Strategy explainer: Full BitYield framework (Variance → Skewness → Kurtosis), backtest metrics, prerequisites skill tree

Strategy Overview

BitYield decomposes options premium into three statistical moments and harvests each independently:

Dimension	Instrument	Signal
Variance	Straddle	Avoid (unbounded in extremes)
Skewness	Risk Reversal	25d RR < −5% → entry signal
Kurtosis	Butterfly	25d BF > 2% → layer on top

**Backtest performance (Aug 2025 – Feb 2026, including Oct/Feb extreme moves):**

Version	Sharpe	Calmar	Max DD
Skew only	1.24	3.50	−1,169
Skew + Kurtosis V1	3.47	7.79	−1,003
Skew + Kurtosis V2	5.09	19.70	−750
