Thanks @nithin for posting this. There are so many ideas in this space but law is not very supportive as compared to other countries.
When you say “data feed is being used for any other purpose, there is a cost to it”, even if I subscribe to Kite Api and use live feed to build a product (not gaming/copy trading) to display live ticker values, will it be allowed or will have to buy feed from NSE?
If have to buy from NSE, it would be prohibitive to experiemet with the ideas.
