Debug?

[jonmoron]

Hi,

I'm having some trouble debugging using VS. I'm able to attach Visual Studio to the NT process and get all of the breakpoints that are located in code initialization to hit. However, OnBarUpdate breakpoints never get hit. In fact, I placed a breakpoint on OnBarUpdate and it never got hit.

Can someone explain why or how this is happening?

thanks!

Jon, did you follow all those steps including using a non express VS version and enabling Debug Mode in the NinjaScript editor?

Bertrand,

Yes. As I said, I was able to get some of my breakpoints to run (those set in the initialize section of my code within VS), however none of the event-code was ever hit (OnBarUpdate, OnExecution, OnOrderUpdate, etc).

thanks-

Instead of using VS, please add a simple print statement within OnBarUpdate() and see if you can get that printed into the NT Output Window.

Josh,

Yes. I have Print statements all over my code.
None of them get printed at all.

Some background. This is a tick-by-tick strategy. I am under the impression that OnBarUpdate gets called with every tick, is this correct?

Completely confused. Any ideas?

Only when running in real-time do ticks get processed every tick. Otherwise it is processing once at the end of each bar. I suggest you try using SampleMACrossOver or any standard indicator to test. You likely have some programming mistakes with your particular script.

Don't strategies run in 'real-time' by default?

I have a Historical check condition since my strategy is a real-time strategy. The ES (the product I'm testing this code with) is ticking live currently.

Let me check the sample strategy and see how that goes.

thanks

Strategies run in real-time only when you actually run it on real-time data. There is no "default" behavior in this regard.

No dice. I've placed breakpoints in VS 2010 in the Initialize and OnBarUpdate methods. The Initialize breakpoint gets hit every time I load the strategy in the Strategy selector within the Chart.

I'm running the strategies via the Chart. Is there another way for me to be running strategies against a real-time feed?

thanks!

Jon,

Please do not be testing Visual Studio at this point in time. You should only be testing regular scripts and ensuring your regular scripts work within the confines of NinjaTrader. Any print statements should show up in the Output Window.

[jonmoron]

Josh,

Ok. I'm connected to a real-time feed. I can see the product ticking in the SuperDom. This means that it is in fact a real time feed, correct? And that the strategy (SampleMACrossOver and my custom strategy) are using this feed, correct?

thanks!

Very well. But I cannot modify the SampleMACrossOver strategy, right?

Please open it up via the NinjaScript Editor, right click > Save As, use a new name, add some Print()s, compile, run the variant on a chart.

Josh,

I modified the sample cancel order strategy and added:

Print("in OnBarUpdate");

as the first line in the OnBarUpdate method.

This is the code I've modified:

As expected, there is nothing printed to the output window.

jonmoron,

How many bars are on the chart you are trying to run the strategy on?
