Still no profits why?

I sold 2 USDINR 5th april 70CE options and 1 69.75CE on 3rd april. On 4th april i bought 69.75CE and then sold 1 more 70CE. At expiry i had 3 sell call 70 options yet I made only 10.5 profit. Why? Where all the premium vapourized? Spot price on 5th april at 12:00 was at 69.4.

How much STT was charged?

No STT is charged on currency options beauty of it. No actually i figured it out when i was claculatin mg from margins calculator it was showing 200 premium per lot but actual premium on the option chain on nse was 25 so it was my mistake. I over calculated my profits while it was 175 less.
