GetOHLC and GetLTP returning errors

Hi Team,

As part of my development using .Net API Client, I have gone through the below error after returning the data.

Below is the code I used.

          /// <summary>
            /// Retrieve LTP and OHLC of upto 200 instruments
            /// </summary>
            /// <param name="Exchange">Name of the exchange</param>
            /// <param name="TradingSymbol">Tradingsymbol of the instrument</param>
            /// <returns>Json response in the form of nested string dictionary.</returns>
            try
            {
                Dictionary<string, OHLC> ohlcs = kite.GetOHLC(new string[] { "MCX:ALUMINI17NOVFUT","MCX:ALUMINIUM17NOVFUT","MCX:COPPER17NOVFUT","MCX:COPPERM17NOVFUT","MCX:COTTONREF17NOVFUT","MCX:CPO17NOVFUT","MCX:GOLDGUINEA17NOVFUT","MCX:GOLDPETAL17NOVFUT","MCX:LEAD17NOVFUT","MCX:LEADMINI17NOVFUT","MCX:MENTHAOIL17NOVFUT","MCX:NICKEL17NOVFUT","MCX:NICKELM17NOVFUT","MCX:RBDPMOLEIN17NOVFUT","MCX:SILVER100017NOVFUT","MCX:SILVERM17NOVFUT","MCX:SILVERMIC17NOVFUT","MCX:ZINC17NOVFUT","MCX:ZINCMINI17NOVFUT" });
                Console.WriteLine(JsonSerialize(ohlcs));
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }



            //// Get LTP of upto 200 scrips
            /// <summary>
            /// Retrieve LTP of upto 200 instruments

            /// <param name="TradingSymbol">Tradingsymbol of the instrument</param>
            /// <returns>Json response in the form of nested string dictionary.</returns>
            try
            {
                Dictionary<string, LTP> ltps = kite.GetLTP(new string[] { "MCX:ALUMINI17NOVFUT", "MCX:ALUMINIUM17NOVFUT", "MCX:COPPER17NOVFUT", "MCX:COPPERM17NOVFUT", "MCX:COTTONREF17NOVFUT", "MCX:CPO17NOVFUT", "MCX:GOLDGUINEA17NOVFUT", "MCX:GOLDPETAL17NOVFUT", "MCX:LEAD17NOVFUT", "MCX:LEADMINI17NOVFUT", "MCX:MENTHAOIL17NOVFUT", "MCX:NICKEL17NOVFUT", "MCX:NICKELM17NOVFUT", "MCX:RBDPMOLEIN17NOVFUT", "MCX:SILVER100017NOVFUT", "MCX:SILVERM17NOVFUT", "MCX:SILVERMIC17NOVFUT", "MCX:ZINC17NOVFUT", "MCX:ZINCMINI17NOVFUT" });
                Console.WriteLine(JsonSerialize(ltps));
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

I received an error.
The given key was not present in the dictionary.

Kindly verify the issue.

Any update on this please?

It seems "RBDPMOLEIN17NOVFUT" is not being traded now. And the OHLC and LTP for the same are not available.

Ok, I will verify and let you know, till then please keep the discussion open.

Hi @ajinsokan,

You are correct. The RBDPMOLEIN is the culprit. I just want to know, is there any reason behind using the Trading Symbols along with Exchange instead of Instrument Token.

I believe it will be good for programmers to use the same kind of standards over the project.

Thanks & Regards,

You can also use instrument token instead of exchange - trading symbol combination.
