Dear Niftyaajkal,
Kindly note that NEST is a third party software sold by Omnesys (now owned by Reuters). For us to be able to offer this software to our clients, we have to pay Omnesys a license fees. Omnesys charges a per segment per user fees to us and we pass the license cost for NEST as is to our clients.
Other brokers offer it for free because they more than make up for its cost by the brokerage they charge, but in case of Finvasia, we dont charge any brokerage so we have to pass this cost to our clients.
If you would like to use a free trading software, we would recommend that you opt for NOW. Its a software directly provided by NSE and hence is free of cost to the brokers.
NOW allows you to trade via desktop application, it also has a web trader and a mobile trader. You can get all three for Free when you open an account with Finvasia.
Many Thanks
Team Finvasia
