    New Updates In Futures & Options

    What are the deadlines to close my long-dated option positions?

    Since the lot size is changing on 30 December, 2025, EOD, all long-dated contracts (Mar/Jun/Sep 2026) based on the old lot size will no longer be tradable in their current structure.

    Therefore, customers holding these contracts must match the new lot size multiples or otherwise square off existing positions before the transition.

    Example:

    Scenario 1: If you hold 975 qty in NIFTY:

    • Lots as per old definition = 13 lots (13 × 75)
    • Lots as per new definition = 15 lots (15 × 65)

    ➝ This already matches the new multiple, so no action is required.


    Scenario 2: If you hold 900 qty (not a multiple of 65)
    ➝ You must adjust the quantity to match the revised lot size.


    Scenario 3: If you hold 1050 qty (not a multiple of 65)
    ➝ You must adjust the quantity to match the revised lot size.

    NOTE: Kindly make quantity adjustments for your open positions to align with revised lot size by December 26, 2025, post which no fresh positions shall be allowed. If your positions are not aligned to the new lot sizes, system shall attempt square-off of your positions from 29 December 2025 (12:30 PM) till December 30, 2025 (12 PM).

    We strongly urge you to:

    • Review your open long-dated index derivative positions
    • Align to the new lot sizes or square off before 12:30 PM on December 29, 2025
    • Please maintain sufficient margins to safeguard your open positions in case of hedge-break
    • Any open positions beyond December 30, 2025 (12 PM) can be squared off only through the Call and Trade facility at 022-41330660
    • Recreate positions from December 31, 2025 BOD with the new lot sizes

    This will help you avoid liquidity issues and ensure a smooth transition when the new lot sizes become effective
