Also adding APIs for brokerage cost calculations will be very useful particularly for options trading. These are very complex otherwise https://zerodha.com/brokerage-calculator#tab-equities
Margin computation API is a good addition. I saw this few back in the API docs but not able to see corresponding API wrappers in .NET library. Are you also going to update the library?
I am looking at a simpler lookup to be used in my program from any NFO instrument to get the corresponding underlying. If "Name" field is used it does not work for some of the NFO instruments where the mapping in "Name" field is not correct. Example…
What's the solution for index? Example Name field for BANKNIFTY NFO's gets to "BANKNIFTY" where the corresponding Index(EQ) is "NIFTY BANK". If this mapping is corrected in the instrument dump it will be helpful.
