Margin F&O MTM

F&O profits available same day

From WebNotes, a public knowledge base. Last updated . Reading time ~3 min.

F&O profits are credited on the same trading day via daily mark-to-market (MTM) settlement, unlike equity which follows the T+1 cycle. This makes F&O profits available for margin purposes overnight, in time for next-day trades.

The cycle

For F&O positions:

TimeEvent
Trading day TPosition opens / closes; MTM tracked through session
End of T (15:30)Daily settlement processed
T evening (~18:00)MTM profit credits to trading account; loss debits
T+1 morningProfits available for new trades

For equity:

TimeEvent
Day TCNC sell executes
Day T+1 eveningProceeds settle to trading account
Day T+2 morningAvailable for new CNC buys

F&O is one day faster.

Why F&O is daily

Daily MTM is the standard for derivatives globally:

  • Reduces counter-party risk.
  • Forces position-holders to maintain margin per current P&L.
  • Allows the exchange to identify losing positions early.

For NRML F&O positions held overnight, each day’s MTM is settled at day close.

Effect on trading

For an active F&O trader:

  • Win on Day T: Cash available T+1 morning for new positions.
  • Lose on Day T: Cash debit T+1 morning.

The cash isn’t usable on Day T itself (the trading account doesn’t update mid-session for MTM). It’s available T+1 morning.

Comparison with equity T+1

Equity T+1 means:

  • CNC sell on Day T → cash on Day T+1 evening.
  • Cash usable Day T+2 morning.

F&O daily MTM means:

  • F&O profit on Day T → cash available Day T+1 morning (one day earlier).

For active F&O traders, this faster cycle improves capital efficiency.
