Hi Igor,

Unfortunately this level of programming is not supported on the forums.

Thanks for the quick response,
I already load dll and call Connected() func. I hoped there's some c++ samples but if no, I continue interfaces exploration by myself.

Regards,
Igor

Unfortunately we just cannot provide any support on this. You will have to play with it on your own. Thank you for understanding.

Thanks you too.

I done something via COM interface.
If somebody interested there is small guide:

1. I added there to stdafx.h:

 
#import "c:\Program Files\NinjaTrader 6.5\bin\ninjatrader.client.tlb"

2. There's my sample code:

 
IClientPtr clt;
if(CoInitialize(NULL)!=S_OK) FatalError("Cant CoInitialize!"); 
AfxOleInit();
HRESULT hr = clt.CreateInstance(L"NinjaTrader.Client.Client");
if( FAILED(hr)) FatalError("Cant CreateInstance IClient!");
printf( "IClient instantiation successful!\n" );

long ret;
if(clt->SubscribeMarketData("ES 12-08")==0)
{
printf("Last = %f\n",clt->MarketData("ES 12-08",0));
clt->UnsubscribeMarketData("ES 12-08");
}
else if((ret = clt->Connected(0))=-1)
{
puts("dll isnt connected to NinjaTrader!");
}
else puts("SubscribeMarketData error");
clt = NULL;

Tip: you will get 2 files in compile directory after compilation:
ninjatrader.client.tlh & ninjatrader.client.tli
Check them for more info about NinjaTraderClient interfaces.

Hello again,

I'm interested also is there any func in API to catch exact trade event?

Thanks,
Igor

Unfortunately we can only support NinjaScript related programming questions. From NinjaScript you can catch trade events either via the OnOrderUpdate() or OnExecution() methods.

Igor,

Did you find anything in the DLL that makes it possible to externally program strategy analysis/backtests...?

Josh, i thought about Ticks handling. Something like NinjaScript's OnMarketData() method...

Can you say me please is it possibly to call external dll from within NinjaScript and put params to dll func?

Can you say also is it possible to get Ninja C++ interface support somewhere else?

igorvlassov,

Both of these are beyond the level of support we can offer on the forums. The information available is in the Help Guide over here: http://www.ninjatrader-support.com/H...heConcept.html
