I received below message from zerodha.
I wanted to carry my position till expiry day,
Will there be a penalty when they square off my position next day morning?
"As per exchange regulations, an additional exposure margin of ₹1408453.61 will be blocked for short option positions on Index Contracts expiring on 27 January, 2026. This is in addition to the margins blocked for current positions.
Please ensure to maintain sufficient funds in your trading account before the market opens to avoid your positions being squared off"
