These premiums are based on today EOD. If index opens on 30th December at the same level, these should be same. There may be minor differences. Anyway, you cannot trade today. So, the date given is 30th Dec 2013.
Different brokers charge different commission. For example, my broker charge Rs. 10 per lot plus transaction charges and stamp duty. So, the total charges will be around Rs. 80. For 5.78 points, I get Rs. 289. So, net profit is still Rs. 200/=. The problem is margin money. If margin money required is Rs. 25,000/=, then you do not get even interest. I think, it is a useless strategy but before discarding it as useless, I wanted an expert opinion of Danji. Sometime, what you feel useless might be useful, so why discard without having expert opinion.

My brokerage is on the higher side, thats why I make a loss even though you will make the profit for the same strategy.
