One could have also played this move via the options route, by rolling over your positions in each of the 4 or 5 expiries. Not necessarily in the same option strike, but one where the premium paid over the ruling price were the lowest. Sure it could have resulted in slippages but one would have been in profits from the 1st expiry itself and all the subsequent adds would have paid for themselves (they would have come from the profits of the 1st expiry). Initial capital employed would have been less that Rs.6000 (Calculation base on an assumption of Rs.150 for the 1st Option). You would have not got 12000 points this way but even if it was 10000 points, it would have been Rs.4 lac profits with an initial investment (Not risk) of Rs.6000. Think about it. Out of the box thinking can do wonders.
