Zerodha is the best share trading brokerage firm in india. It will charge only rs20 per trade.Only one side for intraday and for delivery both sides.In zerodha we can take multiple positions at a time but it will charge only rs20.Compare to Zerodha many brokerage firms like Composite edge they will charge only rs15.But support and charting softwares aren’t good in composite edge but zerodha providing all features with less cost. So I will rocommend Zeroda.
