ATI Communications

[texasnomad]

I wrote a custom application to calculate position size. The next step in the process is to import the price data from NinjaTrader.


I understand that I need the ATI, but where to start? Where are the DLL or COM files? How does my application communicate with NinjaTrader? Please point me to the correct documentation files.

I removed your link with .EXE in it since this is against policy. Following is the starting point in our Help Guide for the ATI.

I wrote a very simple app to test basic communication, which is pasted below. NinjaTrader.Client.dll was copied to the same directory as the .cs file.

When compiling from command:
csc test.cs
The type or namespace name 'NinjaTrader' could not be found. Are you missing a using directive... ?

If NinjaTrader.Client.dll is corrrect, why does the compiler not recognize the namespace?

using System;
using System.Windows.Forms;
using NinjaTrader;
using NinjaTrader.Client;
 
namespace CorrelCalcApp
{
    static class CorrelCalc
    {
        static void Main()
        {
  if (commsCheck == 0) Console.WriteLine("Connected Successfully");
  else Console.WriteLine("Failed to Connect.");
        }
    }
 
    public class Comms
    {
 private Client client;
 int commsCheck = client.Connected(0);
 
 private void OnLoad(object sender, EventArgs e)
        {
            // Create new client object
            client = new Client();
        }
        private void OnFormClosing(object sender, FormClosingEventArgs e)
        {
            // Clean up
            client.TearDown();
        }
    }
}

Unfortunately this is beyond what we can provide support for.

However here is a hint: clicking on the error in VisualStudio brings you to the offending line. From here you can resolve the error with the assistance of the VisualStuatio help system.

Dierk,

Thanks for the extra effort. I got the simple test working using the code below. I thought I would post it here for future reference.

Compiling from Command:
csc /reference:NinjaTrader.Client.dll Test.cs

Test.cs code:

using System;
using NinjaTrader;
using NinjaTrader.Client;
namespace Tester
{
    static class Test
    {
        static void Main()
        {
   // Create an instance from NinjaTrader.Client.dll
            Client client = new Client();
 
   // Reference the "client" instance and Connected() method to make sure NT works properly
   // 0 indicates a good connection.  Non-zero values indicate a failed connection.
            if (client.Connected(0) == 0) Console.WriteLine("Connected Successfully");
            else Console.WriteLine("Failed to Connect.");
        }
    }
}
