Step-by-step procedure

Six steps per the procedure infobox.

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.
