Actually futures margin is less for near month than the far month. Not sure about options but I would guess the same is true for them as well. It’s simple more time means more risk hence more margin. But they also depend on other factors as well.
@siva: My problem statement is, suppose I sell a option priced 0.05 to cashin the premium. But if I use MIS, the RMS team would squareoff at market, which would be a loss for me. If I take the position using NRML, I would be cashing the premium.
As no further exposure is required further, I would recommend you block same amout for MIS and NRML on expiry day.
Because they are willing to take excess risk to attract clients which is not at all advisable at our scale.
One bad day is enough to wipe out the broker and all his clients if these kind of leverages are followed.
Also as I said earlier SPAN system will block at portfolio level, if multiple expiries are involved in one portfolio then this is absolutely not possible because system won’t charge less for one expiry and more for other, it charges accordingly.
@siva: The whole point here is, treating MIS and NRML trades as same on expiry day for blocking funds. There should be a technical feasibility to identify the positions for current expiry and other expiries and block the amt as reqd.
Exposure margin doesn’t logically make sense on exipry day. Broker as per NSE would already be blocking SPAN margin. How do you say they would wiped out. They are blocking funds more intelligently and logically. This would allow funds to be used more effectively if required.
Theoretically what you are saying is right but there is no way to charge differently for different expiries on same product type as our systems are centralized and we follow unique rules/settings for all our clients.
