So here is how it is, the margin required to short options keeps reducing as and when the strike keeps going out of money.. So for eg today, if you had to short 5900 call and hold overnight, margin required is 31000, 6000 call is 29000 and so on and 6500 call is 18000 Rs... Same way the 5500 put the margin required for overnight position is 18000Rs.
Together it is 36000 Rs that is required, which is very close to what is required to short 1 in the money option(32000)... So, yes there is a margin benefit, but not as much...
What we are trying to work with the NOW team is to set in rules where, assuming you are short 5500 put and 6500 calls, but you are also long 5300 put and 6600 calls.. basically a position where the maximum risk is 100 points on nifty( Rs 5000).... We are trying to set rules where you can get this benefit.. with 5000 you should be able to setup the entire strategy... Cheers...
