SPAN Margin

Total Margin = SPAN + Exposure Margin
SPAN (Standard Portfolio ANalysis) calculates minimum margin based on portfolio risk.
Multi-leg strategies get margin benefit — hedged positions require less margin.
Calendar spreads get more margin benefit than same-expiry spreads.
Exposure margin is an additional buffer — typically 3-5% of contract value.
Check margin requirements before trading — insufficient margin = position rejection or square-off.
Pro Tip
Use hedged strategies (spreads) to reduce margin requirements by 50-70% compared to naked positions.
