Scripts: Switching charts

New comment
 

Switching charts:

The script switches all opened charts at a certain interval. It is also possible to display only the charts of certain symbols.

Good evening! Is it possible to loop the script? So that after the end of open charts it would start over again, instead of finishing the work.

In principle, it is possible. But how many cycles should be made? Or like a kaleidoscope - for a whole day?
 
Karputov Vladimir:
In principle, you can. How many cycles do you have to do? Or like a kaleidoscope - all day long?
Well, a whole day would be better.....

In that case, you need an EA in which to call the whole carousel in OnTimer(). I'll think about it.

Added. Fixed the text.

 

Anyway, here is the Expert Advisor. The main thing is to remember that it is a bit problematic to switch off/unload the Expert Advisor when infinitely showing charts :) . Therefore, let me remind you that this Expert Advisor is displayed in the "Navigator" window:

Ah, here is the Expert Advisor itself:

Thank you for your promptness. But the Expert Advisor does not work correctly. If more than two charts are open, the Expert Advisor jumps from the 1st chart to the last chart, skipping the rest between them. And there is no transition from the last to the 1st chart, i.e. the carousel does not work.

The terminal keeps its own internal record of the order of opening charts. And if you shuffle charts in the process of work, it will not change the internal accounting. Conduct an experiment: close all charts, open five new ones and attach the Expert Advisor to chart number 3.

I checked, everything is the same. It switches from the 3rd chart to the last one and then stops. It doesn't switch from the last to the 1st, there is no carousel.

I don't know if it affects it - I have mt4. I renamed the file to mt4 and made a compilation. The earlier script switches correctly....

 

EA version 1.01. Fixed a bug and replaced the variable name. Instead of

Seconds

now the variable has the name

Seconds_
because in MQL4 the word Seconds cannot be used as a variable name. (Help on Seconds).


The Expert Advisor can be used both in MetaTrader 5 and MetaTrader 4 (for MT4 you just need to rename the file).
