Yes,they have 999 plan for month for any number of trading in a month and also 9Rs per executed trade plan(18Rs for buy and sell) for any number of lot or equity.If u compare with zerodha its almost same in brokerage, but Sas is not dealing in commodity trading yet which they said will be starting soon.Also,they have an app for android phones on which you can do trading.I am telling this all because am one of their client .
