Hello llanqui,

There was an error that occurred.

Is this happening when opening any indicator like the SMA, or when opening a specific indicator?

Try running the repair from the NinjaTrader installer.

Hello llanqui,

My theory is something is wrong with a public property.

Can you reduce the script to just the line(s) causing the error and provide an export?

Start by making a copy. After making a copy Exclude the original from compilation. Make sure the copy can reproduce.

Then in the copy remove all code in OnBarUpdate(). Check again it can still be reproduced.

Then remove any added code to OnStateChange(). Check again it can still be reproduced.

Remove any properties you can and still be able to reproduce.

The provide an export of whatever is left that is still causing the error.

To export a NinjaTrader 8 NinjaScript so this can be shared and imported by the recipient do the following:

1. Click Tools -> Export -> NinjaScript...
2. Click the 'add' link -> check the box(es) for the script(s) and reference(s) you want to include
3. Click the 'Export' button
4. Enter a unique name for the file in the value for 'File name:'
5. Choose a save location -> click Save
6. Click OK to clear the export location message

By default your exported file will be in the following location:

• (My) Documents/NinjaTrader 8/bin/Custom/ExportNinjaScript/<export_file_name.zip>
