Unable to create instance of NinjaTrader.Indicator

I wasn't sure where to post this so hopefully I've put this in the right place.

I'm getting this error message wherever I try to put any indicator on a chart:

Unable to create instance of "NinjaTrader.Indicator.ADL". Most likely there is no default constructor defined, or the default constructor does not work correctly: Exception has been thrown by the target of an invocation.

I just started getting this today and it happens when I load any indicator on a chart. I can still compile any indicator without any problems. I repaired the database under Tools/Options/Data. I have looked through the NT support database but couldn't find anything other than the standard, uninstall and reinstall NT which I don't want to do if it's just an issue with one particular indicator.

Does anyone have any ideas or suggestions that I could try that worked for them? Thanks

Is it always the same error (ADL)?

Is ADL a built-in Ninja indicator? If not, try deleting it and exit and restart Ninja.

Also, have you tried making sure you start with a new clean chart, no template?


Due to time constraints, please do not PM me if your question can be resolved or answered on the forum.

Need help?
1) Stop changing things. No new indicators, charts, or methods. Be consistent with what is in front of you first.
2) Start a journal and post to it daily with the trades you made to show your strengths and weaknesses.
3) Set goals for yourself to reach daily. Make them about how you trade, not how much money you make.
4) Accept responsibility for your actions. Stop looking elsewhere to explain away poor performance.
5) Where to start as a trader? Watch this webinar and read this thread for hundreds of questions and answers.

Thanks for your input Mike. I did start with a clean chart, absolutely no indicators and then got the error regardless of which indicator I put on the chart. I did finally resolve the problem.
I chose a random indicator and then went through edit, rightclick >references. In the references I looked for any references to the last indicator that I deleted. I found such a reference and deleted that dll. I then compiled a random indicator without any issues and that seemed to resolve the problem.
I`m not sure why I wasn`t getting the error right after deleting the indicator but maybe it`s because I was loading workspaces that never included that indicator to begin with. I`m just glad I figured it out and didn`t have to re-install.

I know this post is very old, I'm sorry but I had the same problem and I use the ccleaner program for clean the windows register and then reboot. No more problems.

Excuse me for my english if it isn't correct.
