In the money stt
I bought 31000 ce page industry 4 lot at 500, suppose i let it expire in the money and page industry on expiry close at 35000, what will be the stt in it?
if it expires at 3500 … stt will be approximately 44 points
anyway pageind options are illiquid or we can say no activity in the option mkt
The formula is (strike price + premium) * lot size * number of lots * 0.125%.
That said, your STT liability would be (35,000 + 500) * 25 * 4 * 0.125% = 4,437.5.
If you exercise the option then your profit would be (35,000 - 31,000) * 100 = ₹ 400,000 less Tax liability ~ ₹ 395,000. Is that what you made out of 500 * 25 * 4 = 50,000?! Oh boy! Could you please be kind enough to explain your trade?
Option chain shows only 1 lot Open interest, and opening price of that option is 900
I think OP is giving an example?
