Why do exchanges revise the lot size?

SEBI mandates that the contract value of all F&O contracts remain between 5 to 10 Lakhs. In the periodic review (every 6 months), if the contract value of the scrip is beyond this range, there is an upward or downward revision in lot size.

Yes. Once changes come into effect, 2 lots of 50 quantities each will change to 4 lots of 25 quantities each.

10

Surely it will also get reduced. From 1.5lakh odd for 1 lot to 75k.

11

from 75 to 50 and now 25, nifty lot size reduced so much. is it an uncertainty or? reducing lot sizes also reduces the required capital for option selling, by this retailer can participate in option selling, which is good but, after witnessing Sensex, bankex and midcap options premium pluming. like rocket :rocket: in expiries it scares me more and with a daily expiry makes retailers tempt to do option selling every day, if they can’t manage it properly it erodes all their yearly profits in a snap. so please be careful option sellers please dont do option selling in sensex, bankex, midcap,niftyfin. money control

What happens to the margin requirement? Are they reducing the required margin per lot since the new lot size is 25?

If it is 1.25L for 1 Lot of NIFTY (50 qty) would it be 62.5k for 1 lot of NIFTY (25 qty)? Not exact numbers, just estimates.

13

Of course, margin requirements will also be reduced according to changes in lot sizes.

15

If we have May month Contract which has been bought now, do we need to exit the existing May month Contract prior 26th April and then buy new or it will be automatically get converted to 1 lot -2 lot or 2 to 4.? Please clarify.

16

It will be automatically converted.

17

Why the required margin for a nifty lot is shown for 50 instead of 25?

18

Tomorrow the change happens.
