Workflow

  1. Clarify user's market view (direction + conviction) and time horizon.
  2. Fetch underlying spot (
    longbridge quote
    ), option chain expiries, near-term strikes, and call/put volume.
  3. Assess IV from ATM IV in chain vs rough HV proxy (see 
    longbridge-options-volatility
    ).
  4. Select 1–2 strategies from the matrix; explain structure, legs, and cost.
  5. Show example legs using live strikes from the chain (ATM and nearby).
  6. Output structured recommendation (template below).
