Options Payoff, Option P&L Analysis Methodology

Overview

This skill is designed for option strategy analysis scenarios within the Vibe-Trading quantitative framework, covering:

• P&L curve generation for single-leg and multi-leg option portfolios
• Black-Scholes pricing and Greeks calculation
• Implied volatility inversion
• Strategy selection decision support

Constraint: For research and backtesting only. Do not output live trading instructions, in line with the project's guardrails.

Built-in execution tool

Load this skill for methodology, then call options_payoff for production calculations. Pass signed legs (qty > 0 long, qty < 0 short), entry_spot, and expiry_days; optionally pass actual per-share premiums, multiplier, commission, chart bounds, and IV scenarios. The tool returns an expiry curve, a spot × IV scenario matrix, and analytic breakeven/max-risk results that do not depend on the display grid containing every strike.
