Hi @jasdeepwalia,
Historical data API only takes instrument tokens and not tradingsymbol. Check out documentation here.

@jasdeepwalia,
The .net library is a third-party library built by @botany02, maybe he can help you with it.

@jasdeepwalia
Just checked the SymbolList_NSE.txt file, 'NIFTY BANK' symbol is present there.
Working fine on my side...
May be some unknown issue...
As a workaround manually add the symbol details to text file..
Add the below line to SymbolList_NSE.txt file which is present in your Bin Directory.

NIFTY BANK,0,0,260105,NSE-INDICES

Hope this helps
