you trade 10 scrips per week so monthly 40 trades ....
you can Go with RK global 999/- unlimited trading plan only for nse cash ...with their basic web version model 99/- for nse cash... ..so 1100 rs per month ...
in Zerodha simple 40 rs. per trade or .01% of turnover which is low ....it cost you 40*40=1600 rs /- per month ....
