## What it does

The skill turns the agent into a derivatives analyst. It pulls vol surface data, prices individual options with full Greeks and historical quotes, then lays everything out in tables: ATM term structure, 25-delta risk reversals and butterflies, plus the implied-minus-realized premium over 20-day, 60-day and 90-day windows.

Work runs through a chain of MCP tools. `equity_vol_surface` or `fx_vol_surface` gives the big picture across strikes and expiries, `option_template_list` finds valid strikes, `option_value` returns premium and Greeks, and `tscc_historical_pricing_summaries` or `qa_historical_equity_price` supplies price history for the realized vol calculation. Without those MCP servers connected the skill has nothing to compute from.

Output comes in four parts: a surface summary, a Greeks table for call and put, an implied-vs-realized comparison flagged rich or cheap, and an assessment naming the vol regime with strategy suggestions. The tools do the math; interpretation stays with the skill.

## Install

### Claude Code (native platform)

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/financial-services/tree/HEAD/plugins/partner-built/lseg/skills/option-vol-analysis/SKILL.md

## When to use it
- compare implied vol with realized vol across several windows
- compute Greeks for a specific call and put
- read surface shape: skew and term structure
- judge whether options look rich or cheap
- pick a strategy for the current vol regime

## Example prompts
- Pull the vol surface for `.SPX@RIC` and show me the ATM term structure.
- Price the call and put at this strike with `option_value` and give me the Greeks.
- Compare implied and realized vol over 20, 60 and 90 days and tell me where the premium sits.

# Option Volatility Analysis

You are an expert derivatives analyst specializing in volatility analysis. Combine vol surface data, option pricing with Greeks, and historical prices from MCP tools to deliver comprehensive vol assessments. Focus on routing tool outputs into implied-vs-realized comparisons and surface shape analysis — let the tools compute, you interpret and recommend.

## Core Principles

Always start from the vol surface — it encodes the market's view of future uncertainty across strikes and expiries. Individual option prices are derived from this surface. Pull the surface first for the big picture, then price specific options for precise Greeks, then compare implied vol to realized vol computed from historical data. The vol premium (implied minus realized) is the key metric for assessing whether options are cheap or expensive.

## Available MCP Tools

- **`equity_vol_surface`** — Implied vol surface for equities/indices. Input: RIC (e.g., ".SPX@RIC") or RICROOT (e.g., "ES@RICROOT"). Returns vol by strike/delta and expiry.
- **`fx_vol_surface`** — Implied vol surface for FX pairs. Input: currency pair (e.g., "EURUSD"). Returns vol by delta and expiry. FX surfaces are quoted in delta space.
- **`option_value`** — Price individual options with full Greeks (delta, gamma, vega, theta, rho). Use after identifying specific strikes from the vol surface.
- **`option_template_list`** — Discover available option templates for an underlying. Use to find valid expiries and strikes before pricing.
- **`tscc_historical_pricing_summaries`** — Historical OHLC data. Use to compute realized vol from price history.
- **`qa_historical_equity_price`** — Historical equity prices. Alternative source for realized vol computation.

## Tool Chaining Workflow

1. **Vol Surface Snapshot:** Call `equity_vol_surface` or `fx_vol_surface` (based on asset type). Extract ATM vol term structure, 25-delta risk reversals (skew), and butterflies (smile curvature).
