Recently I subscribed wisdom capital’s "freedom plan". Its very batter then Zerodha in terms of brockrage. Zerodha have a plan of 20₹; per order for OPTIONS.
But "Wisdom capital" is totally free. you have just give government charges.
If you BUY AND SELL option lot, you have to give around ₹; 10 for both buy and sell means total 10₹; brockrage.
If you are new in options then its best for you. I have attached my contact note for proof.
Account opening is so easy. You can do it online and also through their coustomer care free of cost.
