How can i get P/E ratio of a stock?

[AlexRajvandary]

I tried this:
string ticker = "appl"// for example
IEXCloudClient client = new new IEXCloudClient(.....);
var stock = await client.StockFundamentals.AdvancedFundamentalsAsync(ticker);

why stock is null?

Try using AAPL instead of APPL

[AlexRajvandary]

Still null

[AlexRajvandary]

class Program
{
private static string public_token ="";
private static string private_token = "";
static async void GetStock(string ticker,IEXCloudClient client)
{
var stock = await client.StockFundamentals.AdvancedFundamentalsAsync(ticker);
Console.WriteLine(stock.Data.symbol);

    }
   
    static void Main(string[] args)
    {
        string ticker = "AAPL";
        public_token = File.ReadAllText("public_token.txt");
        private_token = File.ReadAllText("private_token.txt");

     

        IEXCloudClient client = new IEXCloudClient(public_token, private_token, false, false);
      
        GetStock(ticker, client);

        Console.ReadKey();

    }
}

}

System.NullReferenceException

@AlexRajvandary, you appear to be trying to access https://iexcloud.io/docs/api/#advanced-fundamentals, and endpoint that is only available with paid IEX Cloud plans. I think this could be your problem.

Failing that, you could log out error messages to help identify the issue by modifying your existing code like so:

static async void GetStock(string ticker, IEXCloudClient client)
{
    IEXResponse<AdvancedFundamentalsResponse> iexResponse = 
                               await client.StockFundamentals.AdvancedFundamentalsAsync(ticker);
    if (iexResponse.ErrorMessage != null)
    {
        Console.WriteLine(iexResponse.ErrorMessage);
        return;
    }
    
    Console.WriteLine(iexResponse.Data.symbol);
}

Looks like there was a bug in our code, where AdvancedFundamentals returns an array and not a single value.
But unrelated to that bug, it looks like IEX Cloud does not return anything for many companies when the period is set to Quarter instead of Annual. So you can try it again, but modify your code to be:

            var stock = await client.StockFundamentals.AdvancedFundamentalsAsync(ticker, IEXSharp.Model.Shared.Request.Period.Annual);

Make sure you use the latest prerelease or wait for the next official NuGet.

@vslee huh, not the angle I went for, but good catch on that, you're right.

@JamiePrentice I liked where you were going with teaching people how to help us w/ error messages though.
And also that some data is not available to the lower plans.
