C# How do I get last price.

[ieitani]

Hello,
I am new to NT API.
I have added as a reference client.dll, then got connected.
Managed to send order.
I need to get either subsbscription or getting last price of an instrument.

And,
Do NT has a complete C#.NET sample code that do basic functions?

Thanks in advance.

Hello ieitani,

Thank you for your post and welcome to the NinjaTrader Support Forum!

Are you using the NTDirect.dll located in the C:\WINDOWS\system32 folder?
Have you reviewed the functions available at the following link?

Not exactly, answer here. close ticker. Thank you.

Hello,
I did not find "NtDirect.dll" in System32 like your documentation suggesting.
I did find it however on:
C:\Windows\SysWOW64

p.s. My installation did not installed on Program Files, but did on Program Files (x86) folder.

I run Visual Studio 2013, and when I did attempt to add NTDirect.dll, it gotten rejected by VS. With the message.
'FileLocation\NTDirect.dll' could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component.

I saw some other place another dll of yours "NinjaTrader.Client.dll"...I found it on your Ninja Trader folder on my Program Files (x86) folder \bin directory.

I have added it smoothly (as reference), then set:
using NinjaTrader.Client;
for reference.
then could set a variable:
var client = new Client();
and then got connect:
NinjaClient.Connected(1);
returned 0 for success, was so smooth, no time no delay..
It show that your API is highly robust (as far as I understand programming).

I manage to send an order:
success = client.Command("PLACE", "sim101", "NameOfContract", "BUY", 1, "MARKET", 0, 0, "DAY", string.Empty, "1", string.Empty, string.Empty);

The line above send a Buy order in Market price, I got the popup from NT to confirm the Buy, which I need somewhat to not raise, it since if I will let the code open a position, I won't need to confirm every time, only to have it in a silent mode (if you have it).
If you could answer to it, then I am interested in this answer, but it don't hold in my way now.

You could close this thread/question.

The original quesiton was about getting the last price, and I did manage to find out how, since I don't rest if I post a question.

The code is:
//consider that contract, and success are local variables that are set before the code.
I found out that I need to set subscription before requesting the price.
The number 0, meaning Last Price, and 1 and 2, could mean Ask and Bid (check which).

success = client.SubscribeMarketData(contract);
///get last price.
var lastPrice = client.MarketData(contract, 0);
////unsubscribe
success = client.UnsubscribeMarketData(contract);



I need as well a feed of the change in price, in another Api I was delegating an event, with the signature of the function, and then when subscribing, this function was triggered any time a change in price was made, so I need something similar.

I need as well, a delegation to methods that will confirm to me that an order was filled.

I could post another post, but for who ever started to read this post, maybe the information can be valuable.
As I do intent to contribute with information, as I know when I need them.

Hope I was clear in what ever information I have provided, and technically answered my quesiton.

Good luck to all Api Developers..
Make money, and Ninja is Good. Thanks God.
