The problem happens when converting the JSON to Deedle dataframe.

The first item contains an integer (5) so all data in this column will be an integer. Therefore, it will change a floating-point value (0.35) to an integer (0).

I will look at the code and find a way to fix it.

@DDALY

Please enable the debug log in the API so we can verify the raw response. You need to add Microsoft.Extensions.Logging.Console 2.2.0.0.

The code looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using EikonDataAPI;
using Deedle;
using Microsoft.Extensions.Logging;

namespace EDAPIDotnetFramework
{
    internal class Program
    {
        static void Main(string[] args)
        {
            IEikon eikon = Eikon.CreateDataAPI();
            eikon.GetLoggerFactory().AddConsole(LogLevel.Debug);
            eikon.SetAppKey("app key");
            Frame<int, string> data;
            string testRic = "EMBE132209700.U";
            string testField = "CLOSE_ASK";
            // 19 option rics
            var baseList = new List<string>() { "EDQ202209750.U", "EEMM192404600.U", "EEMR172204500.U", "EGLEE202206500.U", "EGLER172204000.U", "EIXM202306000.U", "EIXQ202207000.U", "ELA202335000.U", "ELE202226000.U", "ELE202227000.U", "ELE202228000.U", "ELE202229000.U", "ELE202231000.U", "EMBA192408900.U", "EMBA202309500.U", "EMBE132209100.U", "EMBE132209350.U", "EMBE202209400.U", "EMBG152209000.U" };
            var testRicList = new List<string>() { testRic };
            var fields = new List<string>() { testField };
            // create list of 20 rics with testRic being the first in the list
            var frontOfList = testRicList.Concat(baseList);
            data = eikon.GetData(frontOfList, fields);
            var closeAskFront = data.Rows[0][testField];
            Console.WriteLine($"{testRic} {testField}={closeAskFront} [FRONT of list]");
            // create list of 20 rics with testRic being the last in the list
            var backOfList = baseList.Concat(testRicList);
            data = eikon.GetData(backOfList, fields);
            var closeAskBack = data.Rows[19][testField];
            Console.WriteLine($"{testRic} {testField}={closeAskBack} [BACK of list]");
            Console.ReadLine();
            return;
        }
    }
}

Then, we can verify the raw response.

Hi @Jirapongse, Thanks for getting back. I'm using .NET Framework 4.6.1 which does not support the logging code above. I did upgrade the sample app to use .NET Core 3.1 and confirmed that it actually fixes the problem but the bad news is, I can't upgrade my own app (I tried!) due to dependent libraries. So I'd like to find a solution with .NET Framework 4.6.1 if that's possible. Please advise how I can get you the diagnostics you require on that version.

@DDALY

You can use the GetDataRaw method instead. This method will return a string.

Then, check the value or compare it with .NET Core 3.1 application. To compare the data, you need to run the applications at the same time.

@Jirapongse, Ok progress - on .NET Framework 4.6.1, GetRawData() actually returns the correct data but GetData() doesn't. Below is the Deedle Frame returned from GetData() and also the string returned from GetRawData(). Any ideas? Thanks.
