AROON

What AROON does?

This API returns the Aroon (AROON) values. The related REST API documentation is here

---

Including the AROON namespace

The very first thing to do before diving into AROON calls is to include the right namespace.

using Avapi.AvapiAROON

How to get a AROON object?

The AROON object is retrieved from the Connection object.

The snippet below shows how to get the Connection object:

...
IAvapiConnection connection = AvapiConnection.Instance
connection.Connect("Your Alpha Vantage API Key !!!!");
...

Once you got the Connection object you can extract the AROON from it.

...
Int_AROON aroon = 
	connection.GetQueryObject_AROON();

Perform a AROON Synchronous Request

To perform a AROON request you have 2 options:

1. The request with constants:

IAvapiResponse_AROON Query(string symbol,
		AROON_interval interval,
		int time_period);

2. The request without constants:

IAvapiResponse_AROON QueryPrimitive(string symbol,
		string interval,
		string time_period);

Perform an AROON Asynchronous Request

To perform an AROON asynchronous request you have 2 options:

1. The request with constants:

async Task<IAvapiResponse_AROON> QueryAsync(string symbol,
		AROON_interval interval,
		int time_period);

2. The request without constants:

async Task<IAvapiResponse_AROON> QueryAsync(string symbol,
		string interval,
		string time_period);

Parameters

The parameters below are needed to perform the AROON request.

• symbol: The name of the equity
• interval: The time interval between two consecutive data points in the time series.
• time_period: Number of data points used to calculate each AROON value.

Please notice that the info above are copied from the official alphavantage documentation, that you can find here.

The request with constants

The request with constants implies the use of different enums:

• AROON_interval

AROON_interval: The time interval between two consecutive data points in the time series.

public enum AROON_interval
{
	none,
	n_1min,
	n_5min,
	n_15min,
	n_30min,
	n_60min,
	daily,
	weekly,
	monthly
}

---

AROON Response

The response of a AROON request is an object that implements the IAvapiResponse_AROON interface.

public interface IAvapiResponse_AROON
{
    string RawData
    {
        get;
    }
    IAvapiResponse_AROON_Content Data
    {
        get;
    }
}

The IAvapiResponse_AROON interface has two members: RawData and Data.

• RawData: represents the json response in string format.
• Data: It represents the parsed response in an object implementing the interface IAvapiResponse_AROON_Content.

Complete Example of a Console App: Display the result of a AROON request by using the method Query (synchronous request)

using System;
using System.IO;
using Avapi.AvapiAROON;

namespace Avapi
{
    public class Example
    {
        static void Main()
        {
            // Creating the connection object
            IAvapiConnection connection = AvapiConnection.Instance;

            // Set up the connection and pass the API_KEY provided by alphavantage.co
            connection.Connect("Your Alpha Vantage API Key !!!!");

            // Get the AROON query object
            Int_AROON aroon =
                connection.GetQueryObject_AROON();

            // Perform the AROON request and get the result
            IAvapiResponse_AROON aroonResponse = 
            aroon.Query(
                 "MSFT",
                 Const_AROON.AROON_interval.n_1min,
                 10);

            // Printout the results
            Console.WriteLine("******** RAW DATA AROON ********");
            Console.WriteLine(aroonResponse.RawData);

            Console.WriteLine("******** STRUCTURED DATA AROON ********");
            var data = aroonResponse.Data;
            if (data.Error)
            {
                Console.WriteLine(data.ErrorMessage);
            }
            else
            {
                Console.WriteLine("Symbol: " + data.MetaData.Symbol);
                Console.WriteLine("Indicator: " + data.MetaData.Indicator);
                Console.WriteLine("LastRefreshed: " + data.MetaData.LastRefreshed);

                foreach (var technical in data.TechnicalIndicator)
                {
                    Console.WriteLine("AroonDown: " + technical.AroonDown);
                    Console.WriteLine("AroonUp: " + technical.AroonUp);
                    Console.WriteLine("DateTime: " + technical.DateTime);
