DrawingTools w/PriceLevels Issue

[tradeesh]

I am wondering what was the solution for the error mentioned by many people here. Why not post solution here?

I am getting same error when I am trying to create a custom drawing tool.

Hello tradeesh,

Thank you very much for your post.

This error indicates that a script has been corrupted, e.g., because it was overwritten.

Resetting the custom and internal scripts will resolve this. To do this, please first navigate to Documents > NinjaTrader 8, and rename the "bin" folder, e.g. to "bin-old".

Once renamed, please perform a repair installation to replace this folder by following the steps below:

• Shut down NinjaTrader
• Go to your computer's Control Panel > Programs & Features (Note: search for 'Control Panel' to find it within the Windows Start Menu. This will be a different window than the Settings page)
• Left-click once on NinjaTrader > select 'Repair' above the list of available programs
• Restart the platform after it finishes repairing, and test for this behavior again.

Please don't hesitate to let me know if you have any further questions about this!

NinjaTrader_Manfred the solution you gave me is basically reinstalling Ninjatrader, so it will remove all the custom script. The goal here is to keep the custom script I've modified and run it.


Simply restarting the Ninjatrader make the error go away but whenever I modify the script on any place, it comes back up again. Everytime it comes up I have to restart the Ninjatrader which is annoying.

Line number 239 is causing problem in PriceLevel.cs.
Please see attached screenshot.

Hello tradeesh,

You can delete the @PriceLevels.cs file from Documents\NinjaTrader 8\bin\Custom\DrawingTools, and then run the repair to replace only this one file with the original.

Hello tradeesh,

I've run into this issue multiple times in the past and also have issues with Fibs at times. Attached some screen shots if it helps. Version 8.1.3.1. This issue causes the message box to pop up over the chart.

Hello neo302,

This appears to be a custom script and not the @PriceLevels.cs file from NinjaTrader, also this appears to be Visual Studio and not the NinjaScript Editor of NinjaTrader.

Hey Chelsea,
OK. This code is from my @PriceLevels.cs file and is in line ~182. Is this not around line 182 of bin>Custom>DrawingTools>@PriceLevels.cs ?
If not, maybe an indicator I downloaded overwrote it? It says this at the top:
//
// Copyright (C) 2024, NinjaTrader LLC <www.ninjatrader.com>.
// NinjaTrader reserves the right to modify or overwrite this NinjaScript component with each release.
//
Also, yes, I use Visual Studio to code.

Thank you

Hello neo302,

Delete the file from Documents\NinjaTrader 8\bin\Custom\DrawingTools and run the NinjaTrader 8.1.3.1 installer to replace the file with the original.

Hey ChelseaB,
Just FYI, I renamed the original file, did the install and used an app to compare them and the files are identical.
Thanks
