8.1.4.1 update not saving time frame on strategy analyzer

[NinjaTrader_ChelseaB]

Hello ClauTrade,

If you are compiling and the value is being reset, this is not the issue of this thread. That issue has already been reported.

We are testing typing a value, saving a template or workspace (without compiling), and then reopening the workspace or reloading the template.

With the exact steps shown in the video, and no other extra steps, are you experiencing different behavior than what is shown in the video?

Hello Chelsea, I lost just this detail in post #11 ... I got it!

Yes, without saving the reset to 1 minute is after compiling. Saving a template the reset is after Run.

I think it was a new bug from 8.1.4.1 but nothing has changed in 8.1.4.2 ... do you know if 8.1.4.0 works fine about this?

Please I hope you can fix soon, you know, it is just bit hard to develop and test, re-setting every time the data series!

Thanks. Regards

Hello ClauTrade,

As mentioned in post # 11, the issue with the data series parameters reverting to default after clicking run has been previously reported and is marked for correction in a future release of NinjaTrader.

To confirm, you are not experiencing the issue of this topic with the data series parameters not saving with a workspace or in a duplicate window?

Hello Chelsea,

yes, I tested all combinations ... your video is a partial fix of the problem .. in your video you never RUN the strategy after default saving.

As I wrote at last of my post ...with default set save it keep set with compilation but reset to 1 minute at the end of RUN!

Check please if you get same issue .. thanks!

Hello ClauTrade,

Please watch the video in post # 3.

With the exact steps in the video is the behavior different.

Hello,

what about this bug? In last version 8.1.4.2 64-bit it is still resetting to 1 minute depending from compilation script too.

It seems keep setting but after a script compilation reset to 1 minute and sometimes it seems to keep set but at the end of RUN back to reset to 1 minute.

Saving setting to template (own or default) something change but finally always (with compilation or at the end of run) back to reset to 1 minute.

Thanks

Hello zagier,

Unfortunately, there has not been a new release of NinjaTrader at this time and the current version is 8.1.4.1 so there are not any new updates on this.

[zagier]

It also continues to default back to 1 minute, even with a default set, whenever I leave an optimization run going for awhile, log out of the remote session, log back in and when the run finishes it has switched - the run did execute on the chosen time frame, but the display continues to revert back, so if I go to execute again changing my parameters but don't notice the time frame flipped I get a wasted run. So frustrating.

Any update on this?

I am trying 8.1.4.1 again in my dev environment as I want the bug fixes and memory usage improvements but now also seeing the issue occur when I change workspaces. A strategy analyzer for different instruments has the data series value from one workspace being changed by the other one, never saw this happen before. Seems like there is a lot of random changes going on with this field for sure.

I had an issue with 8.1.4.1 in my production environment where the chart running a strategy froze on four occasions over three days, so I have definitely rolled back to 8.1.3.1 there, not sure if that has been brought up yet by others.

Hello burmaz,

Thank you for the information.

Our development is looking into the issue.

Hello burmaz,

"The hours template selected also keeps changing every time I run a back test."

This has been reported to our development.

See the post linked below.

https://forum.ninjatrader.com/forum/ninjatrader-8/platform-technical-support-aa/1328942-strategy-analyzer-parameters-revert-to-defaults-in-8-1-4-1?p=1328996#post1328996

This thread is about the data series interval (time frame) reverting to default.

So far I have not reproduced the interval changing, but I may not have the correct steps.

zagier, please let me know if there are different steps than what I showed in the video that I should take to result in this behavior.

Yes I understand what this thread's topic is. What I am saying is that I am experiencing the SAME issue that the OP is experiencing, AND when it occurs, the hour template resets too. These issues seem to be connected.


In addition to the reset to 1 min like what the OP is experiencing, it also will occasionally randomly reset to other previously used time frames. The issue is pretty disruptive in my work flow to rerun backtests over and over and to have to catch when ninjatrader randomly changes the time frame.

I have since reverted to the previous NT version b/c this bug is too disruptive for my uses.

I see the video, thank you. The default template is helping in that scenario, however I'm still finding scenarios where it occurs. I'm still confused because this never happened before the latest update.

It just now occurred again on an optimization run (that took 1.5hrs) where I had it set to 1600 tick, changed some of the parameter ranges, and then when the run was done it showed 1 min again and it had run on 1 min timeframe instead of the 1600 tick. This has happened a few times over the past two weeks, I haven't narrowed down the exact scenario to replicate the behavior though.

I am too experiencing this issue. This issue has never happened prior to this update. The hours template selected also keeps changing every time I run a back test. This is definitely a new problem that did not exist with previous versions.

I don't even have to open and close any windows for the issue to arise. I can just rerun a backtest on an already opened strategy analyzer window and it keeps reverting to 1 min and the hourly template keeps changing.

[zagier]

I will look at trying to get a solid set of reproduction steps for you. It still just seems to happen randomly, where I'm off writing code on my other machine, look at a chart, and then come back to run a strategy analyzer or optimization again only to realize it had yet again swapped to 1 min.

For now I will roll back to 8.1.3.1 in my dev environment. Quickly scanning the release notes for 8.1.4.1, I don't think I need any of the new features, although I do see some bug fixes on strategy analyzer, so I'll refer back to this too if need be.

Hello zagier,

From my experience compiling has always cloned new instances to populate the Strategy Analyzer drop-drown since NinjaTrader 8 was first developed.

If you would like to test the previous version, you can download this from the Account Portal.

Did you compile?

Can you reproduce this with the Sample MA Crossover included with NinjaTrader?
