Fynance Examples

What data you can get with Fynance:

  • Get Security Info
  • Get Quotes
  • Get Events
    • Get Dividends
    • Get Splits
General Usage

First you have to add the Fynance namespace to make the types available on your code:

using Fynance;

The Fynance implements a fluent interface to read data from a stock market api. Given it, a instance of Ticker is a representation of a security on the stock market. Then you can make an instance of Ticker and use all the methods to configure what you want to have until call the Get method. There is a async version of this method called GetAsync. The following code is a sample of use:

var result = await Ticker.Build()

The Build method instance the Ticker object and all these Set methods configure what information you want to get from the available APIs.

To the the events as we call dividends or splits you can use SetDividends and SetEvents to define it:

var result = await Ticker.Build()

Alternatively, you can use the method .SetEvents(true) and it will set Dividends and Splits.

When you call the Get methods, you get a instance of FyResult. It contains all the data following the methods configured over the Ticker. The FyResult can contain all the information from the Security, the OLHC history, dividends and splits.


There are many information you can read from the security, see some samples available:

var currenty = result.Currency;
var symbol = result.Symbol;
var symbol = result.ExchangeName;

Reading all the OLHC history:

foreach (var item in result.Quotes)
   var period = item.Period; // DateTime
   var open = item.Open; // Decimal
   var low = item.Low; // Decimal
   var high = item.High; // Decimal 
   var close = item.Close; // Decimal 
   var close = item.Close; // Decimal 
   var adjClose = item.AdjClose; // Decimal 
   var volume = item.Volume; // Decimal

Reading the dividends:

foreach (var item in result.Dividends)
   var date = item.Date; // DateTime: Payment date 
   var value = item.value; // Decimal: Payment value

Reading the splits:

foreach (var item in result.Splits)
   var date = item.Date; // DateTime: Event Date 
   var numerator = item.Numberator; // Decimal: Numerator of splits
   var denominator = item.Denominator; // Decimal: Denominator of split
