Comment on Basics on Options Shorting/Writing
ah.. 🙂 , Got your question… In options, buying side anyways is 0 STT, so the STT shown on the calculator is the selling side only.. If you look at the default example on http://zerodha.com/brokerage_calculator , QTY is 400, buy price and sell price is mentioned, the STT which shows as Rs 7 is what is required to write the option..
