I am asking for help from the community...
MT5
Unable to perform optimization by overshooting parameters on multiple pairs at the same time.
When I select "All symbols from Market Watch" option in the tester under "Symbol" it disables the ability to set overshooting of input parameters in the "Parameters" tab, just no checkboxes are checked and no values are entered. What should be done ?

Could not do optimization by overshooting parameters on multiple pairs at the same time.
When I select "All symbols from Market Watch" option in the tester in the "Symbol" column it disables the ability to set overshooting of input parameters in the "Parameters" tab, just no ticks and no values are entered. What should be done ?

is not optimised on a few characters, just tested

 
Mikhail Mishanin:

is not optimised on multiple characters, just tested

And it has to go through the parameters for each symbol in a separate test ?
The same in MT4. So the possibility of multi-currency testing in MT5 is a myth ?

UPD However, the documentation explicitly says :

  • It should be understood that specifying a symbol does not mean that the tester will only use this historical data. Information on all symbols used in the EA, the tester loads it automatically.
I.e. one symbol is supposed to be selected with parameter sets, and the tester will then apply these parameters " to all symbols involved in the EA ".
 
MikeZv:

Do I have to go through the parameters for each symbol in a separate test?
In MT4 the same way. So multicurrency testing in MT5 is a myth ?

.....

Do you understand the difference between the words "testing" and "optimisation"?

 
Сергей Таболин:

Do you understand the difference between "testing" and "optimisation"?

Is characterby character testing or optimisation?

 
Vitaly Muzichenko:

So he needs to know on open positions

how to calculate the commission for open orders in mt5 for each pair separately?

Yes, my mistake. By enumerating positions on each pair)

 
Hi all, does anyone know where the crosshair on the chart in the MT-5 strategy tester is switched on or if it is there at all?
 
Yuriy Vins:
Hi all, does anyone know where the crosshair on the chart in the MT-5 strategy tester is enabled and is it even there?

Middle button on the mouse (click on the scroll wheel)

 

friends who can tell me how to set a trailing stop,

Yuriy Vins:
Hi all, does anyone know where the crosshair on the chart in the MT-5 strategy tester is turned on, or if it is there at all?

Ctrl+F

But only when testing with visualisation.
