India is 25 years behind the US in terms of stock markets, brokers, trading and everything else. I think brokers in India have to first get more people to trade before they look at making money from these value added services. Most of the discount brokers have less than 30000 active clients. Even if 3000 people paid Rs 100 for an additional service, they make Rs 3lks. Out of this 3lks there will be a running cost (including the vendor cost). So net they might might make 1.5lks. This is how much a 20 seater office will cost to run.
SEBI is also contemplating increasing minimum networth requirements and deposits. This is to ensure things like Kassa, Unicon etc doesn't happen.
So unless a lot more people start trading in India in the next 2 to 3 years, most of these discount brokers will disappear. The only hope then is that VC's will invest into some of these brokers (like Upstox, Samco), which will give them more time to survive.
