Intraday vs Positional F&O
Intraday F&O involves opening and squaring off all positions within the same trading session, while positional F&O involves carrying open positions overnight or for multiple sessions, with significant differences in margin requirements, psychological risk, and gap risk.
The distinction between intraday and positional F&O is not merely a time-horizon preference; it creates fundamentally different risk profiles and operational requirements. Most retail participants begin with intraday trades because the margin is perceived as lower and the capital at risk appears bounded by the trading day. However, this perception needs significant nuancing.
Intraday F&O on NSE does not receive an explicit lower margin rate the way intraday equity trades do (where margins can be reduced to 20-25% of delivery margin for intraday equity). For F&O, NSE requires full SPAN plus exposure margin to be available before the trade is placed and throughout the day under the peak margin framework introduced in 2020-2021. Brokers may offer intraday F&O with slightly adjusted margins for very short-duration trades, but this is a broker-level policy choice, not an exchange mandate. The peak margin rule — which checks margin utilisation at random intraday snapshots and penalises shortfalls — effectively ended the era of high-leverage intraday F&O at most regulated brokers.
Positional F&O carries gap risk that intraday trades do not. When major news — corporate announcements, geopolitical events, overnight global market moves — breaks outside Indian market hours, the opening price can differ sharply from the previous close. A long futures position held overnight during a global selloff can open with immediate MTM losses that require same-morning margin top-up. This gap risk is the reason why risk management for positional F&O requires a larger capital buffer than merely maintaining the exchange-prescribed minimum margin.
From a tax perspective, both intraday and positional F&O profits are treated identically — as non-speculative business income. This is different from the equity segment, where intraday is speculative and delivery is capital gains. The identical tax treatment means the intraday versus positional choice in F&O is purely strategic, not tax-motivated.
Options strategies like calendar spreads and diagonal spreads are inherently positional because they involve contracts across different expiry dates. These strategies benefit from the differential time decay between near and far expiry, which can only be captured by holding positions overnight. For such strategies, understanding theta accrual across sessions, weekend decay (time decay continues over weekends even though markets are closed), and expiry-week gamma dynamics are all part of positional F&O management.
