Why use the calculator
- Pre-trade planning: Verify margin before committing.
- Strategy comparison: See margin for different option strategies.
- Hedge optimisation: Verify the SPAN reduction for spreads.
- Capital sizing: Plan how much capital you need.
When the calculator may differ from order ticket
- SPAN file refresh: Mid-day SPAN updates may not be in the calculator instantly.
- Your account state: Calculator is generic; order ticket considers your specific position.
- Cross-position hedge: Order ticket accounts for existing positions; calculator is hypothetical.
For the most accurate margin for an actual order, use the Kite order ticket; for planning, the calculator is fine.
