We need software to be written for calculating various scrips on NSE in the Options segment for calculating the premiums, giving the risk return (Sharpe ratio) and other broad parameters. The key thing is the software should be "dumbed down" to use. Basically what we are interested in is a return on our money of greater than 4% per month. We are willing to lose a part of the premium occasionally, if we get a good return rate of 4 to 5% per month. If we are satisfied with the performance of the software after using it for a week, we can consider paying additional amount upto US$ 400.00
