As Nac bro told, its GCI platform of Meta trader 4. Its is demo version. Here you could get Real time chart of Nifty in Demo version. But then if you opt for paid forms you can get all charts for every stock and indicies without spending extra sums on data feeds.
Having said this, data in GCI is slightly delayed, may be by few seconds..
If you want to avoid the time delay, you can use similar platform like GCI, which is FXCENTRAL. Here also you can have Demo and paid versions, and as usual the Demo version has less symbols.
Here again, FXCentral is also compounded with problems, in the sense, that, they are slowly shifting to MT5, FROM MT4..
So, for those who have definite set of Custom indicators working in MT4, may not get them used in MT5.
I think i am pouring lots of things..which certainly will confuse any newbies to MT4 OR mt5.
Take care
