## What it does

The skill covers 18 strategies, from covered calls and protective puts to iron condors, calendar and diagonal spreads. For each one it works out max profit and loss, Greek exposure and position size. For earnings plays it pulls the report date and compares implied volatility against historical.

Under the hood are Python scripts. You need Python 3.9+ with `numpy`, `scipy`, `requests`: `pip install numpy scipy requests`. Without an FMP API key the skill runs on manual inputs — the stock price and volatility you supply. With a key (`FMP_API_KEY` or the `--api-key` argument) it fetches the current price, historical volatility, dividends and earnings dates.

Pricing uses the European model. That undervalues American options, so check the number against your broker if early exercise matters to you. Implied volatility comes from your input; when it is missing, the skill computes 90-day historical volatility and suggests plugging in the market IV instead.

## When to use it
- price a call and a put with Black-Scholes
- work out iron condor P/L and breakeven points
- read delta and other Greeks on an open position
- compare a protective put against a covered call for hedging
- size a position before an earnings straddle

## Example prompts
- Price a call on AAPL: strike 185, 30 days, volatility 0.25, and show the Greeks
- Work out the P/L on a 180/185 bull call spread, 10 contracts
- Should I buy a straddle before NVDA earnings? Compare IV with historical volatility

# Options Strategy Advisor

## Overview

This skill provides comprehensive options strategy analysis and education using theoretical pricing models. It helps traders understand, analyze, and simulate options strategies without requiring real-time market data subscriptions.

**Core Capabilities:**
- **Black-Scholes Pricing**: Theoretical option prices and Greeks calculation
- **Strategy Simulation**: P/L analysis for major options strategies
- **Earnings Strategies**: Pre-earnings volatility plays integrated with Earnings Calendar
- **Risk Management**: Position sizing, Greeks exposure, max loss/profit analysis
- **Educational Focus**: Detailed explanations of strategies and risk metrics

**Data Sources:**
- FMP API: Stock prices, historical volatility, dividends, earnings dates
- User Input: Implied volatility (IV), risk-free rate
- Theoretical Models: Black-Scholes for pricing and Greeks

## Prerequisites

**Required:**
- Python 3.9+ with `numpy`, `scipy`, `requests`

**Optional:**
- FMP API key (for real-time stock prices and historical volatility)
  - Set via `FMP_API_KEY` environment variable or `--api-key` argument
  - Without API key: Use manual inputs for stock price and volatility

**Installation:**
```bash
pip install numpy scipy requests
```

**Quick Start Examples:**
```bash
# Basic call option pricing (no API key needed)
python3 scripts/black_scholes.py

# With FMP API key for real-time data
python3 scripts/black_scholes.py --ticker AAPL --api-key $FMP_API_KEY

# Custom option parameters
python3 scripts/black_scholes.py --stock-price 180 --strike 185 --days 30 --volatility 0.25

# Put option analysis
python3 scripts/black_scholes.py --stock-price 180 --strike 175 --days 30 --option-type put
```

## When to Use This Skill

Use this skill when:
- User asks about options strategies ("What's a covered call?", "How does an iron condor work?")
