Hello Unclepips,

The only $ in the code provided is in the print you have. What version of NinjaTrader are you currently using? The $ syntax for strings was only recently supported so if you are using an older version that code likely won't compile. You could use

Print("Skipping trade due to " + news.Key + " event at " +eventTime);

[Unclepips]

Hi- thanks for taking a look at this. I use NT version 8.0.28.0 64-bit

[NinjaTrader_Jesse]

Hello Unclepips,

That would be the reason, you would have to update to the current release to use the newer C# features. 8.0.28 is using an older C# version than the current release which supports C# 9. The $ syntax is a newer C# feature.

[Unclepips]

Thanks for helping fix the "$" error. This is my first time trying to code something I had never done before. I am still learning bits and pieces.

Hello Unclepips,

That would be the reason, you would have to update to the current release to use the newer C# features. 8.0.28 is using an older C# version than the current release which supports C# 9. The $ syntax is a newer C# feature.

I had issues with the newer version. NT supporter was supposed to call me a couple of weeks ago, but no one did. Before that when I spoke to one of your colleagues she helped me to upgrade from the older version that I had to this 8.0.28. She said I could just use it until someone called to help me straighten things out. I actually bought NT to license for multiple brokerages. Thanks.

Hello Unclepips,

Unfortunately I can't look up your support logs from the forum, if you still need assistance with updating and wanted a call you can do that by emailing [email protected]. Generally when someone schedules a call they will provide a specific time and date to ensure we can reach you.

[Unclepips]

hi- I called and spoke to someone yesterday, he mentioned that an email will be sent to me to set up an appointment, but I have not seen any email.
by the way, I was able to solve the crashing part. I had to uninstall and delete all ninjascripts that I had ever owned on my computer, and then the computer allowed me to install the new NT 8.1.4.1. Thanks.

[Unclepips]

would it be possible for you to look at this script making sure it is compliant with NT 8.1.4.1?

Hello Unclepips,

If you still are waiting for an email please check your spam folder to make sure you didn't miss it. If you still don't see it you will need to email in to [email protected]. I would suggest always using email directly for any support requests so you have a case number that can be referenced, if something gets missed we can look up the case number to find out what was sent out.

Regarding compliant code, are you seeing any errors? The only reason you had an error originally was due to the version being used and using a newer C# feature that was not available in 8.0.28. If you aren't getting any compile errors you can try and run the code in a chart.
