An options-trading advisor skill — Claude structures thesis, checks Greeks, and surfaces risk before you hit send.

trading_skills turns Claude into a disciplined options-trading co-pilot: you state a thesis, the skill walks you through structuring the trade (strategy choice, strike/expiry selection), checks Greeks and expected move, and flags risks. It does not give financial advice or execute orders — it's a checklist and reasoning partner so you don't trade on vibes.

How to structure an options trade from a thesis

👤 Self-directed options traders ⏱ ~25 min advanced

When to use: You have a directional or volatility view and want to express it cleanly.

Flow
  1. State the thesis
    Thesis: SPY moves modestly higher over the next 21 days; IV is elevated. What strategy fits?✓ Copied
    → A ranked list of suitable strategies with tradeoffs
  2. Pick strikes
    Given current SPY at $X and IV Y, propose a bull put spread. Show Greeks at entry and at expiry edges.✓ Copied
    → Strike selection + Greeks table
  3. Risk check
    What's max loss, breakeven, POP, and how do I manage if it goes wrong?✓ Copied
    → Explicit numbers + adjustment plan

Outcome: A fully-shaped trade you understand before placing it.

Pitfalls
  • Trade size too large for account — Skill prompts 1–2% risk-per-trade discipline; re-ask with account size
  • Ignoring earnings/events — Always verify there's no event inside the tenor
Combine with: filesystem

Check your overall portfolio Greeks before adding a trade

👤 Multi-position traders ⏱ ~15 min advanced

When to use: You've got several positions and want to know if a new trade adds diversifying or concentrated exposure.

Flow
  1. Summarize current portfolio
    Here's my open positions. Compute total delta/vega/theta exposure.✓ Copied
    → Aggregated Greeks
  2. Evaluate the proposed add
    If I add this new position, how do the aggregate Greeks change?✓ Copied
    → Before/after Greek table

Outcome: A more informed sizing / structuring decision.

Pitfalls
  • Ignoring correlations across underlyings — Treat SPY, IWM, QQQ as correlated; don't count them as independent diversification
