Hello! Please help me to understand:

How does the virtual trailing stop work?

How is it better than a regular trailing stop?

Can I prescribe a virtual trailing stop in my Expert Advisor if there are many orders at the same time for each pair, and will that be rational?

You can prescribe a lot of things in the EA. The virtual stop (both StopLoss and TakeProfit) can be of two varieties: individual for each order, and common for all EA orders (or even an account - as configured). Virtual (individual) stops simply replace the standard stops and are not seen by the brokerage company. Whether they are better or worse than the standard stops is a trader's personal preference. While we should remember that a standard stop will work without a running trading platform, virtual stops require a constant connection to a server.
When virtual stops work, an Expert Advisor monitors the price for crossing a preset level and closes the order when such an event occurs. With ordinary stops this process is monitored and completed by the DC server.

Hi all!

I need to pass a command from one EA working on one terminal to another EA working on another terminal.

The command is simple: "Start working!" / "Finish working!"

That is, the second EA works when the first one allows it.

Who has a ready solution?

I am grateful in advance for the help I have received many times here.

I'm pretty much guessing through a file. "Maybe there's a ready-made solution?"

File mapping is the same file, but it's in RAM, not on disk. Vadim has a ready-made solution, nothing complicated. The header file has all the instructions on what to do and how to do it.
There are examples in the test script.

Studied file operations in MQL. It turns out:files can only be opened in terminal_directory\experts\files (quote).

That is, from another terminal this file is not visible!!!
