DX

What DX does?

This API returns the directional movement index (DX) values.

---

Including the DX namespace

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

using Avapi.AvapiDX

How to get a DX object?

The DX 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 DX from it.

...
Int_DX dx = 
	connection.GetQueryObject_DX();

Perform a DX Request

To perform a DX request you have 2 options:

1. The request with constants:

IAvapiResponse_DX Query(string symbol,
		DX_interval interval,
		int time_period);

2. The request without constants:

IAvapiResponse_DX Query(string symbol,
		string interval,
		string time_period);

Parameters

The parameters below are needed to perform the DX request.

• symbol: The name of the equity of your choice
• interval: The time interval between two consecutive data points in the time series.
• time_period: No description available

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:

• DX_interval

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

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

DX Response?

The response of a DX request is an object that implements the IAvapiResponse_DX interface.

public interface IAvapiResponse_DX
{
    string RowData
    {
        get;
    }
    IAvapiResponse_DX_Content Data
    {
        get;
    }
}

The IAvapiResponse_DX interface has two members: RowData and Data.

• RowData: represents the json response in string format.
• Data: it is not implemented yet, but it represents the parsed response in an object implementing the interface IAvapiResponse_DX_Content.

Complete Example: Display the result of a DX request

using System;
using System.IO;
using Avapi.AvapiDX;

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 DX query object
            Int_DX dx =
                connection.GetQueryObject_DX();

            // Perform the DX request and get the result
            IAvapiResponse_DX dxResponse = 
            dx.Query(
                 "MSFT",
                 Const_DX.DX_interval.n_1min,
                 10);

            // Printout the results
            Console.WriteLine(dxResponse.RowData);
        }
    }
}
