off late at the start of series, combined premium of nifty atm ce & pe has been in the range of around 125/130 = 255/260
if you choose to buy ce & pe at 250 up & down, it would cost you in the range of around 45-50 i,e. 45+50 = 95/100
thus you shall get the premium of approx 250/260 & pay the premium approx 100, and you will have margin of safety upto 260-100= 160 point point from the point of your trade
after that you shall be in loss, but maximum to the extent of bought ce or pe, i.e. maximum 90-100 point
decide accordingly
