This Expert Advisor is example of use of the Memory Mapping DLL for working with File Mapping functions.
In this example the Expert Advisor create a virtual (memory-mapped) file and start to update the quotes on symbol.
Using this way, Expert Advisors can exchange data (for example, quotes) using common memory-mapped file.
The format of the memory-mapped file is the same as used in MetaTrader 4 Expert Advisor. It means that you can exchange quotes between МetaТrader 5 and МetaТrader 4.
The other data exchange can be organized using the similar way.
The code has a lot of comments and logs.
