Exchanging data between two EAs running in different terminals - page 5

Yes! Mapping is the best way!

You just have to remember to lock the mapping files behind you.

That's weird!... It turns out that it matters in what place of the function memory is allocated?

The important thing is how.

So, is it really important for you to allocate a buffer of a strictly defined size?

Yes!!! That is, quite, interesting!

The best way to exchange data between programs, IMHO, is through virtual files:

Everything works reliably and without glitches.... Tested electronically :)

+100, both in terms of speed and reliability.

 
Maybe someone can explain the virtual files in more detail to an inexperienced person. Something I wanted to do in my copier. I don't know how.

Joining in. Vinin will figure it out himself after all. Us country folks would really appreciate having a finished code. This is the first time such a tempting opportunity has sounded, and it's a sin not to see it through.

 

I'm about to write a universal library for mapping. Also, Ilnur showed me examples.

I haven't started for a couple of weeks, but haven't continued...

I need it all now. I'll be sure to do it.

 

For starters:

Thanks for the idea! Could you present any example of how to apply this approach in MQL4? That is, I would like to see ready-made examples (scripts or Expert Advisors), from which I could already start doing something for myself.

I already cited an API library with an example for working with registry. I would like some analogue for virtual files.

Thanks in advance!

It 's not MQL, but it's a C++ library that exchanges data between terminals based on shared memory (aka virtual files).

There's a lot of unnecessary stuff for the current question, but it may be useful... good luck.
