Hello kuro6090,

Below is a link to the connection guide for Interactive Brokers.

You can attach Visual Studio to the NinjaTrader Process and run scripts and do debugging.
Below is a link to the help guide.

Hello, ChelseaB

Thanks, ChelseaB
I connected to Interactive Brokers and attached to Ninja Trader 7 from Visual Studio 2019.
However, I am trying to debug by running a strategy on the Ninja Trader 7 chart (9984|TSEJ), but the error shown in the attached image appears.
Since the value of Close[0] is also "0", I feel that Visual Studio 2019 is not picking up market data.
The Ninja Trader 7 chart (9984|TSEJ) is correctly connected to the market data and displaying the chart.

How can I get market data in Visual Studio 2019?

I've attached an image changed to English.
The error message is in English below.

"Object reference not set to an instance of an object."

Hello kuro6090,

The message is telling you there is a null object.

It will not be possible to call an indicator in the Initialize() method. It will be null as there is no data being processed yet.

You will need to call the ATR in OnBarUpdate().

Hello, ChelseaB

Thank you, ChelseaB

I see, you can't call the indicator inside Initialize.

How can I get it through OnBarUpdate for debugging?

[NinjaTrader_ChelseaB]

Hello kuro6090,

protected override void OnBarUpdate()
{
    if (CurrentBar == 0)
    {
        SetStopLoss("", CalculationMode.Percent, SongiriTesiuu * ATR(ATRLength)[0], true);
    }
}

Excuse me, ChelseaB

I can only use Japanese.
So I can't tell you very well.

I want to stop and debug at a breakpoint in OnBarUpdate, but I can't stop at a breakpoint in OnBarUpdate.

I think this is because it has never passed OnBarUpdate. How can I get OnBarUpdate to pass?

[NinjaTrader_ChelseaB]

Hello kuro6090,

Break points can be hit in OnBarUpdate as the script is running in NinjaTrader.

The steps to attach to the debugger are:

1. Open project from Documents\NinjaTrader 7\bin\Custom
2. Correct NinjaTrader.Core.dll and WilsonORMapper.dll references
3. Ensure script is included in project
4. Enable debugging mode in NS editor
5. Attach VS to NT process
6. Compile NS editor (F5)
7. Add break point
8. Run script

Hello, ChelseaB

Thank you very much!

Thanks to that, I was able to see the market data in VS.

Thanks to ChelseaB.

I'm sorry for the wrong name.
I fixed everything.

What is refresh interval or it is realtime?

[NinjaTrader_ChelseaB]

Hello FXZig,

Welcome to the NinjaTrader Forums!

Are you asking if real-time data from Interactive Brokers is real-time or are you asking kuro6090 if they are looking at historical data or real-time data?

Hello FXZig,
Are you asking if real-time data from Interactive Brokers is real-time or are you asking kuro6090 if they are looking at historical data or real-time data?

I mean in this example https://ninjatrader.com/support/help..._debugging.htm do we have really real-time data? Will be nice if that is true.
Thanks for response ChelseaB.

Hello FXZig,

Real-time data comes from your connected broker or data provider.

If you are subscribed to real-time data with your broker or data provider, then this would cause OnBarUpdate() to run in real-time, including if you have attached the process to Visual Studio.
