NT8 Crash issue

[ClauTrade]

Hello dear support,

I'm develope a complex strategy using StrategyBaseConverter Class.

I get an issue but I have test the following:

1. NT desconnected, with No active connection
2. With a simple "refresh" of the parameters window the buton "Enabled" of the strategy become active
3. Turning ON the strategy return a window error and then the NT go in crash and Windows close NT!

I have prepare the most simple strategy "SampleMACrossOver", I save like "TestRefresh", I add only a button to refresh parameters. I add the strategy to download here.

Variable:
ShowHideToggle = true;

In the property:
[RefreshProperties(RefreshProperties.All)] // Needed to refresh the property grid when the value change
[Display(Name = "Toggle show/hide", Order = 1, GroupName = "Use Case #1")]
public bool ShowHideToggle
{ get; set; }

Here the problem... I have test in Two NT8.

Refreshing the parameters with the botton, the "Enabled" button of strategy go ON.




Turning ON the Strategy it return error window




And then only is possible to close the software.





Is possible to avoid this issue please?

Many thanks.

Hello ClauTrade,

Thank you for your post.

The strategies need an account and the accounts are only available when connected to the proper data feed/brokerage connection. In the case of the Sim101 account you can connect to any connection except the Playback Connection in order to use the Sim101 account. Essentially, you must be connected to a data feed to use the Sim101 account in your strategy. There is no means around this.

Please let me know if you have any questions.

Hi Patrick,

I have data provider and real account ...this is not my problem.

Normally the strategy cannot turn ON if there is not connection.

The problem is that, in this case, refreshing the parameter the "Enabled" button become "active" (this is strange!) and the consequence is a strong error (windows close NT).

I think that the button must be inactive after the refresh of the parameter.
Why it become active without connection? Is possible to avoid this with code?

Thanks.

Hello ClauTrade,

Thank you for your patience and for re-iterating what you detailed.

This has been reported to development and I will let you know if I have any word back on this item.

Hello ClauTrade,

Thank you for your patience.

Can you attach the unprotected version of your TestRefresh.cs to your response?

I look forward to your response.

Hello Patrick!

I Attacked the file in my first post ...(.. hope unprotected! ) ...

Of course I attach it again here.

Many thanks!

Hello ClauTrade,

Thank you for your response.

That would be a protected version. When exporting DO NOT select the option 'Export as compiled assembly'. Please refer to the attached screenshot.

Hello ClauTrade,

Thank you for your response.

I attempted to recreate this with my own script and I could not. I also test your strategy but could not reproduce the behavior.

Can you please advise what version of NinjaTrader 8 you are using by going to Help > About in the NinjaTrader Control Center?

In addition, please save a workspace that only contains one chart with the strategy applied to it (RefreshTest specifically) and then attach that workspace to your response. The workspaces are located under Documents\NinjaTrader 8\workspaces on your PC.

I look forward to your response.

Hello,

I did set a workspace with one basic chart (no indicator), only with strategy TestRefresh.

NT8 version: 8.0.8.0 64-bit (Standard)

Thanks.
