When I started trading online I used hdfc trading account those dogs charged me nearly 1 percent of total amount .
Then I went to motilal oswal here I started doing options where they charge 50rs per lot for buying and 50 for selling , my friend said that thats too higher amount.so we traded using his ventura account which charged 35 per lot for buying and 35 for selling a lot.
Then I came to know vns finance where they said whatever the amount of trade they dont care they said they ll charge us per order executed and its Rs 20. So I started using their account for trading regularly and the nse now app is little difficult to use and they should change user interface for easy handling!
