How to Install and Use interchange
1. Storage: Place library files in the MQL/Libraries directory to ensure they are accessible to your projects.
2. Implementation: Include the library in your code using the #import directive, ensuring you match the exact function names and parameters.
3. Compilation: Ensure the library is present in the directory before you compile your main EA or script, as the compiler links them during this phase.
4. Management: Keep libraries organized in sub-folders if you manage many custom functions to maintain a clean project structure.
Frequently Asked Questions
Q: What is a library file used for? A: Libraries store reusable code modules, allowing you to centralize common logic used by multiple EAs or indicators.
Q: Is a library executable? A: No, libraries are non-executable files containing functions; they must be imported into an EA, indicator, or script to function.
Q: Can I update a library while the platform is running? A: You should compile your EA or script after updating a library to ensure the latest code changes are integrated.

why this is needed:this class can help organize data exchange between your programs in case you create products for the market or if you do not want to use system dlls.
for other cases, there are for connecting applications. the exchange is implemented using simple structures.
usage options:
it is necessary to pass data from an expert to indicator or to another expert;
it is necessary to create an indicator that displays information to multiple windows (or to the main window and subwindow);
it is necessary to set up visualization of the calculated values for an expert, in which all the required calculations are made.
how to work with it:
here is an example of transferring data from an expert to an indicator.
in the expert
1.1. create an instance of the class:
1.2. in the set the prefix for names of the global variables. to avoid conflicts with other instances of the class, set a unique name for each of them:
1.3. the algorithm operation is implemented using custom events. simple add the line below to the handler:
if the data for transferring is ready (in the example it is the exp_data structure), it is necessary to call the method:
1.4. do not forget to destroy the class instance during the program deinitialization:
in the indicator
2.1. create an instance of the class:
2.2. in the set the prefix for names of the global variables. it has to match the source - must be the same as in point 1.1.
2.3. to start the process of data transfer, it is necessary to call the getdatastart() with the ind_data parameter (structure to write the data from the expert);
2.4. the algorithm operation is implemented using custom events. add the line below to the handler:
if the data transfer process is completed, the method:
returns true.
2.5. do not forget to destroy the class instance during the program deinitialization:
