Sudden error during compilation of strategy

[BankRobber]

I'm getting this error during compiling my strategy.
Please look at the attached picture.
Funny thing is that if i try to compile the indicator which contains same instructions everything is fine. When i have written that piece of code everything worked fine, after a week or so, I'm just getting an error during compiling. If i remove that line everything goes well. Recently I've removed one indicator which was protected assembly and installed the new version, and it seems to me my problems started from that point.
My strategy had calls to that protected indicator, but I'm not using that indicator anymore in my strategy.
Any thoughts?
update: Can't select the strategy from the new strategy window. look at attached picture 2,3 on the 3rd picture you can see I've selected my BreakOut strategy, and all the parameters from the previously selected strategy remained in the strategy window.


This is my list of declarations from the strategy:
#region Using declarations
using System;
using System.Collections;
using System.ComponentModel;
using System.Diagnostics;
using System.Drawing;

BankRobber, yes this has likely to do with the compiled assembly you installed - which NT7 version are you using here? Are you sure the assembly was created for the version you're using?

To test: just uninstall the assembly again via File > Utilities > Remove NinjaScript Assembly and then recompile your scripts.

NT Version 7.0.1000.7. Uninstalled the protected assembly, recompiled the strategy , but nothing, everything is same

[NinjaTrader_Bertrand]

Did you restart NT7 after the uinstall so the assembly would not be loaded up?

[BankRobber]

Of course i did. and the strategy doesn't make any calls anymore to that indicator
When i try to add the strategy I'm getting this error:

**NT** Failed to call method 'Initialize' for strategy 'BreakOut2/145f88c59f5f4427ae4a19471b284f97': Object reference not set to an instance of an object.

[NinjaTrader_Bertrand]

Calling any property / method from the indicator would not be necessarily needed to see the issue.

Can you please post the Initialize() of the strategy where you're not getting the error on?

Thanks, I would try commenting out parts of it and then rechecking, like the logic you have in there for BetterRenko would give you issues, as we would not support dynamically adding of series.

Thanks for your help, I figured it out.
I've declared a variable called 'Bars' LOL Yeah, stupid i know.

Didn't think of that, thanks for sharing and glad to hear you could resolve it.
