Yeah, vc++ swallows it, but gcc doesn't want to

 

Character names are truncated in the optimiser GUI caches


This is especially true for custom characters - the names there are often long.

 
A100:
Thank you. You can clearly see that the type from the template parameter cannot be used in the declaration of a new class.

I open a EURUSD chart and run this script from the QB on it. It keeps a detailed log as it runs... As a result, I have a chart with a new symbol in which bars and ticks are taken from the side.

Using this symbol I can start any EA using real ticks.


I have made a short optimization, instead of single run. About an hour after finishing it was no longer possible to make a "Run Single Test" from Optimisation results - the ticks have disappeared. So this is a 100% reproducible method.

If you use Tester/Optimizer without long pauses, even on different characters, the ticks don't disappear. Probably the ticks are removed by cleaning up some Tester caches.

A character name cannot be longer than 32 characters, including the termination 0. That is, in fact, 31.

Found and fixed.

The 28-character names in the screenshot are cropped.

Thanks. If we continue to talk about custom ones, there are two situations with them

Is there any way to fix this by the next build?

When I switch to another account, the custom symbol chart loses bars - "Waiting for update". Bars can't be requested. At the same time ticks - no problem.

After restarting the Terminal, of course, the bars on the chart are available.

I would like the custom symbol bars to remain available without rebooting after switching to another account.

CustomTicksReplace(Name, 0, LONG_MAX, Ticks);

It takes a minute at 24 million ticks to successfully execute this function. Is it possible to speed it up?

2.

About 28 characters will check.

2. It may be possible to speed it up, but it's not the first priority.

Give details on the first point. We need a clear reproduction.

Give details on the first point. You need a clear playback.

  1. You open two accounts on different trading servers.
  2. Run the script on EURUSD. When the script finishes, a custom symbol will be created and its chart will be opened.
  3. Switch to an account from another trade server.
  4. You will see "Waiting for update" in place of the chart of the custom symbol.
  5. There will be no bars (ticks will be - CTRL+U) until you reload the Terminal.

3. Switching to an account from another trading server.

Switching is tantamount to loss of communication... it is possible that in this case it will come down to this https://www.mql5.com/ru/forum/275574#comment_8485737
