Can I utilize Shares as margin limit for my Option Buy (Call/put) open position?

If you hold an open Options Buy position (Call and/or Put), here’s what may happen:

1. For intraday position: You may utilise the SAM limit and hold an open buy option position for your intraday.

2. For overnight position: In case you bought Options with Shares as Margin limit and have carried forward the buy position, you may get a payin obligation which is required to be paid in cash . If your Cash limits are not enough to meet the Margin requirements, your existing option position will be squared off to recover the shortfall amount. For e.g.: if you bought Options with SAM amounting ₹1,00,000 and did not square off in Intraday. Assuming your Cash limits are ₹50,000 then you shall get a pay in obligation for the shortage amount i.e. ₹50,000 (1,00,000-50,000).

Essentially, when you buy an options contract, you are required to pay only the premium amount upfront as cash. However, if you are unable to meet any subsequent margin/premium obligations arising from that position, the trading system can automatically square off (sell) those bought option positions to recover the deficit margin amount owed to the exchange.

This is done to ensure you maintain adequate margins as per the exchange requirements for the options positions you hold. The system takes this action to prevent any shortfall of margins payable to the exchange for the open derivative positions in your account.

So in summary, if your free available margin is insufficient for the premium/obligation due, the trading platform can sell off your existing bought call and/or put option contracts to make up for the required margin amount payable. This is an automated risk management measure.
