If you are struggling with HIGH brokerage charges for option selling, then JM Financial is best for you. It costs only 2Rs/Lot, best for those who have less capital (<10L) Thanks @(DJ)itrade capital solution Private Limited. Sir for suggesting me.

Just for example, suppose if you sell 1 lot of 17000PE at 25/- and buy at the same price, which is 25/-, then your brokerage charges as per @Zero will be 49.76/-. But if you do that same thing at JM Financial, the overall charges will be close to 7.5/- only. SEE THE DIFFERENCE

My whole point is if you are small retailer then brokerage cost matter a lot. So Choose Wisely.

And another important thing I am not related to JM Financial in any way, just want to share the experience here.
