EasyLanguage to NinjaScript

[RobinT]

also,

[DllImport("NTDirect.dll")]
public static extern int TearDown();

if (TearDown() == 0)
{
if (File.Exists(localFilePath + fileName))
{
try { File.Delete(localFilePath + fileName); }
catch { Console.WriteLine("Cannot Delete " + fileName); }
}
}

doesn't work either, so I cant disconnect and reconnect the interface.

TearDown() returns 0, but does not disconnect.

[RobinT]

[DllImport("NTDirect.dll")]
public static extern int Last(string instrument, double price, int size);

sets up the dll,

if (Last(sym, close, 100) == -1)
{
System.Console.WriteLine("There was an error calling ninja - terminating execution");
FileOK = false;
}

sends the data.

if there is no connection, one is not established.

Hello RobinT,

Thank you for your response.

Please provide the full lines of code used to verify this on your end.

the guide says

int Connected(int showMessage)

Returns a value of zero if the DLL has established a connection to the NinjaTrader server (application) and if the ATI is currently enabled or, -1 if it is disconnected. Calling any function in the DLL will automatically initiate a connection to the server. The parameter showMessage indicates if a message box is displayed in case the connection cannot be established. A value of 1 = show message box, any other value = don't show message box.

"Calling any function in the DLL will automatically initiate a connection to the server"

if that does not work, how do I do it?

when I have connected manually to external the Last is passed through to NT correctly.
when I am not connected the last is ignored and nothing happens. It does not connect automatically.

Correct, it would not be expected to connect automatically based on a Command.

Calling any function in the DLL will automatically initiate a connection to the server, but that doesn't seem to happen with Last.

When you use the Command for the Last price, what is occurring?

[RobinT]

yes, and I am referring to the dll commands.

Hello RobinT,

I am not sure I follow your inquiry. Are you connecting via the External Data Feed connection? - http://ninjatrader.com/support/helpG...connection.htm

[RobinT]

Do you know how to connect the external interface via program.
teardown disconnects
and connected shows the status.

Calling any function in the DLL will automatically initiate a connection to the server, but that doesn't seem to happen with Last.

Hello RobinT,

The NTM and NTD formats are not published.

[RobinT]

Project has gone well and all working.

I am now trying to get data into the system automatically. As I cannot call the historical data manager, I am trying to create the .nta file myself. Is the format published?

[RobinT]

yes, I am using the

[DllImport("NTDirect.dll")]
public static extern int Last(string instrument, double price, int size);

interface, and time is not passed to NT through this interface from TS or any other source.

Hello RobinT,

Are you stating the data when received by NinjaTrader from TradeStation is not timestamped?

[RobinT]

Yes, and TS data is not timestamped. I was just trying to deal with the tiny discrepancies that occur at the end of a bar due to different clocks.
