I've got news... With Global Datafeeds, u can get both rolling as well as contract wise data for all futures and options - equity, currency and commodity.
To get rolling data, use symbols NIFTY-I, NIFTY-II, etc.
To get contract wise data, use symbols NIFTY14MAYFUT, NIFTY14JUNFUT, etc.
For weekly contracts like INDIAVIX, u can get contract wise data with symbols INDIAVIX14MAYFUTW1, INDIAVIX14MAYFUTW2, etc.
There are issues - like missing ticks (I understand that this is a issue with the NSE feed itself), and that they don't provide tick data.
And about Amibroker, I am not happy with things like they don't have a proper Renko chart, etc.
Even with all these issues, is it worth paying the premium for ESignal?

Well, if you are a serious trader and want to trade with proper data , its the only option right now.
Global data feed may have contract wise data , but their feed software has issues like hanging , missing data..etc.
and about price , there is not much difference between esignal and global data feed if you are trading a big account.
Problem is most people here trade small account and hence their profits are not enough to cover the data price.
Think of it this way, Trading is a business and like any business you have expenses and esignal is one of them.
If you know any other reliable hassle free NSE authorized data provider with hassle free charting application , let me know.
