Input values being reset when switching tabs.

[Mr Yaroslav Troshchey]

Hi everyone :),

I've currently got a freelancer working on an EA for myself and there's one strange bug that I can recreate but they are unable to.

Basically when changing variables in the 'input' tab on the strategy tester I find that they get automatically reset if I tab out of the 'input' tab and go back in.

I'm not really sure what could be causing this issue but any help would be massively appreciated.

Cheers,

[Mr Yaroslav Troshchey]

Just to follow up on this, when values for variables have been changed any new backtests are done with the changed variables but the inputs tab still shows the old variables.

However, running a second backtest uses the original unmodified values in the inputs tab.

After various testing I have found out that my instances of MT5 installation seem to reset the inputs for variables in EA's no matter which EA is running. I have never had this happen before so am unsure as to what the fix is.

Would massively appreciate any support as i'm unable to backtest anything at the moment.

I have tried multiple broker platforms and they all have the same issue, have even tried to set it up on a different PC but no luck there.

I have seen this on some of my MT5 installations. Some do it, some don't.  

I switched all my testing to use a live broker account, and things seemed to have settled down with regard to the Inputs Tab problem.  I documented this and other issues here https://www.mql5.com/en/forum/305758 .

I found that MT5 latest build 2006 and build 2007 have many issues with the testing environment.  Looking the issues up is now a little difficult as it seems you can't search for 'build 2007' anymore. The MetaQuotes search engine now returns no forum articles for 'build 2007' or 'build 2006', which indicates they have blocked the search terms to prevent people looking up issues with these builds.  

I hope an improved release addressing these issues comes out very soon!

Thank you for the reply! I thought I was the only one with this issue.

I will try a live account and if that fails just MT4.

I don't suppose you can download older builds of MT5, or does it automatically update?

even with the update today 15 March 2019, the same problem.

Where is the new update? I still only have access to the February version of MT5

[Mr Yaroslav Troshchey]

Just a quick update, I tried using a live account but it made no difference, still not able to change input values.

I'm also having the same issue. If I change an input variable on the inputs tab of the strategy tester then tab out of it and tab back in, all my metrics revert back to their defaults.

I believe I am running the latest MT5 on a windows 7 Machine.

Was anyone able to determine the fix?

Nothing yet, it seems to be hit or miss at the moment.

I've tried the latest version of MT4 and that seems absolutely fine and older versions of MT5 have been fine for me it's just the latest version.
