Debug Code Line by line?

[elkinm]

I am new to ninjascripts so I am trying to learn by going thorough the build in indicators and strategies.

What I want to do is start an indicator and see the code execute line by line and see the data and variable as they come in and how they are handled.

Thanks,
elkinm

Just as an update, I saw in previous posts that it is possible to debug in VS Pro which requires attaching to the NT process. But it seems to be hit or miss.

Is there a complete set of instructions or an official guide of how to do this?

Thanks again.

Hello elkinm,
Welcome to the forum and I am happy to assist you.

Yes, you can debug NinjaScript codes via Visual Studios. Please refer here to know more http://www.ninjatrader.com/support/h..._debugging.htm

You can also refer to this post which further discusses some easy way to debug a code

Please let me know if I can assist you any further.

you can add a print command after each line and it will print it to the output window


#region variable

if ( variable > 0 ){ X_COUNT = 1; }

if ( variable < 0 ){ Y_COUNT = 3; }

#endregion

Print("some variable = " + X_COUNT + " / some other variable = " + Y_COUNT);

Thank you, that was exaclty what I was looking for.

What i do is create a variable and comment out the one i am not using [or just change the 0 to a 1]

//int debug = 0;
int debug = 1;

then later in the code call it as a condition for all of the print lines

if ( debug == 1 ){ Print("some variable = " + X_COUNT + " / some other variable = " + Y_COUNT); }

if ( debug == 1 ){ Print("some other statement"); }

that way i can turn all my debug output off or on with one variable

This works, but do I have to re-compile in debug mode every time I start NT, and re-load the files in VS as it does not work otherwise.

Also, NT seems to crash frequently when debugging after hitting F10 or F11 and I have to start all over again. Is this typical when debugging?

Hello elkinm,
Unfortunately debugging via Visual Studios is not supported by us. I leave this thread open for any forum member to through more light on it.
