Important for Option Traders: Understand the changes in lot size in coming days + Schedule of changes

Hi Traders, By now, we are all aware that the lot size for index futures and options contracts has increased from November 20, 2024. But has it really? For example, the lot size for Nifty nearest expiry options is still 25, while for the 2nd January options, it is 75, and then it reverts to 25 for the 30 January options. So, what exactly is the lot size for Nifty and other index derivatives? And if it is changing, when do these changes actually take effect? It is confusing, isn’t it? No worri…

There is not going to be any penalty for this.
There is no problem with March 24000 PE x 1200 qty. It is in multiple of 75 so you can exit it anytime you wish.
For March 23000 PE & 25000 PE, you will not be able to exit it now. It will be carried till the expiry date. Since you have bought the options contract, the margin requirement will be simple - qty x buy avg price (premium paid)

Hope this clarifies.
