Update on Fundamentals - Jan 2021

IEX has updated their Fundamentals endpoints in 2021 to be called now "Advanced Fundamentals". This advanced fundamentals dataset is a pass-through to New Constructs. It should be noted that New Constructs is significantly cheaper than IEX, so it is recommended to integrate with New Constructs directly for fundamentals. New constructs covers very large companies, but mid-caps and small-caps are hard to find. If that's the type of thing you're looking for, I'd recommend checking out the Shardar dataset on Quandl.

Examples

• Initialize a formatter object

IEXFormatter formatter = new IEXFormatter();

• Get IEX Symbols

IEXClient client = new IEXClient(IEXBaseUrl.SandboxUrl, token);
string symbols = await client.GetIEXSymbols();
List<IexIexSymbol> symbolsList = formatter.FormatIexIexSymbols(symbols);

• Get advanced fundamental data

IEXClient client = new IEXClient(IEXBaseUrl.SandboxUrl, token);
string advancedFundamentalsJson = await client.GetTimeSeriesFundamentals("MSFT", "annual", new DateTime(2000, 1, 1), DateTime.Now);
List<IexAdvancedFundamentals> advancedFundamentals = formatter.FormatTimeSeriesFundamentals(advancedFundamentalsJson);

• Get historical prices

IEXClient client = new IEXClient(IEXBaseUrl.SandboxUrl, token);
string historicalPricesJson = await client.GetHistoricalPrices("msft", "5d");
// string result = await client.GetHistoricalPrices("msft", "5d", chartCloseOnly: true);
List<IEXHistoricalPrice> historicalPrices = formatter.FormatHistoricalPrices(historicalPricesJson);

• Get dividends

IEXClient client = new IEXClient(IEXBaseUrl.SandboxUrl, token);
string dividend = await client.GetDividends("MSFT", "1y");
List<IexDividend> iexDividend = formatter.FormatDividends(dividend);

• Streaming news

IexSseClient client = new IexSseClient(IEXBaseUrl.SandboxSseUrl, token);
client.NewsEvent += (sender, e) => 
{
    System.Console.WriteLine(e);
};

await client.SubscribeToNewsStream("spy", tokenSource.Token); // Blocking
// client.SubscribeToNewsStream("spy", tokenSource.Token); // Non-blocking

See the tests for all examples: IEXClientTests.cs and IexSscClientTests.cs
