NINJA DLL is NOT listening

[Lucero]

Hello,
From a Visual C# app through NinjaTrader.Client.dll I have been able to subscribe to the market data and get the last price, but I cannot place orders because the dll is not listening: Connected() returns -1 and a Powershell check returns -1 too:

PS C:\Users\sodif> Add-Type -path "c:\Program Files (x86)\NinjaTrader 8\bin64\NinjaTrader.Client.dll"
PS C:\Users\sodif> $atiTest = New-Object NinjaTrader.Client.Client
PS C:\Users\sodif> $atiTest.Connected(1)
-1.

ATI is enabled, port 36973, NT8 is connected to Continuum Demo data feed. How can I make it listen?
Thanks.

Hello Lucero,

There is not any documentation available for interfacing with the DLL's so this inquiry falls under the "unsupported" territory.

We will only be able to point you to information that exists on our Forums.

Here are a few links to some discussion threads that touch on this:

These threads are helpful, but I still cannot get the API working as it should. For instance, when I try this suggestion

[System.Runtime.InteropServices.DllImport("C:\\Wind ows\\SysWOW64\\NtDirect.dll")]
public static extern int Connected(int showMessage);

, VS throws an error upon calling the Connected() method:

Failed to initialize COM Library(0x80010106)

Any suggestions on how this could be fixed?

Hello Lucero,

As assistance with the API is unsupported and beyond the scope of services we provide for our clients, I will take a step back from this thread.

Hopefully other clients will be able to share their experiences with you and provide some direction.
