Algorithms trading live stock data
This is what I found on the internet:
There is no free lunch here in the data segment.
1)You have to get into the datafeed agreement with NSE. And Realtime datafeed is quite costlier as per year charges come around Rs: 20 lakh per exchange + Service Taxes.
2)Per user fee will be applicable depending upon how you are planning to monetize the datafeed. Normally per use fee for NSE cash/futures segment is Rs: 360/user and first 300 users will be waived off.
3)You have to define yourself as data vendor or data redistributor or you are planning to show the exchange data at free of cost.
4)You can lower you cost by getting the data from data redistributor(e.g globaldatafeeds) as normally your fee would be reduced by 20%. However still you have to get data vending agreement with NSE exchange. Without NSE’s permission you are not allowed to vend the data or redistribute the data even if you are doing it at free of cost. Otherwise you will be tagged as a illegal data vendor as per DOTEX.
5)Only Data Redistributor (aka Authorized data vendors like globaldatafeeds, esignal, bloomberg...etc) develop their own API not the exchange itself.
6)However if you are looking for low cost options then you can prefer snapshot data or 15min delayed datafeeds. And the same above rules are applicable for most of the exchanges.
