PLUS_DI

What PLUS_DI does?

This API returns the plus directional indicator (PLUS_DI) values.

Including the PLUS_DI namespace

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

using Avapi.AvapiPLUS_DI

How to get a PLUS_DI object?

The PLUS_DI 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 PLUS_DI from it.

...
Int_PLUS_DI plusdi = 
	connection.GetQueryObject_PLUS_DI();

Perform a PLUS_DI Request

To perform a PLUS_DI request you have 2 options:

1. The request with constants:

IAvapiResponse_PLUS_DI Query(string symbol,
		PLUS_DI_interval interval,
		int time_period);

2. The request without constants:

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

Parameters

The parameters below are needed to perform the PLUS_DI 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:

• PLUS_DI_interval

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

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

PLUS_DI Response?

The response of a PLUS_DI request is an object that implements the IAvapiResponse_PLUS_DI interface.

public interface IAvapiResponse_PLUS_DI
{
    string RowData
    {
        get;
    }
    IAvapiResponse_PLUS_DI_Content Data
    {
        get;
    }
}

The IAvapiResponse_PLUS_DI 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_PLUS_DI_Content.

Complete Example: Display the result of a PLUS_DI request

using System;
using System.IO;
using Avapi.AvapiPLUS_DI;

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 PLUS_DI query object
            Int_PLUS_DI plus_di =
                connection.GetQueryObject_PLUS_DI();

            // Perform the PLUS_DI request and get the result
            IAvapiResponse_PLUS_DI plus_diResponse = 
            plus_di.Query(
                 "MSFT",
                 Const_PLUS_DI.PLUS_DI_interval.n_1min,
                 10);

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