selnomeria: Is there any way to pass GLOBAL variables directly, without passing them as parameters everytime,
| Pass them once, have the library remember the values. |
If your library is for internal use only, you can implement it completely in a header file. Then there will be no need to have a library as an external compiled file. Then you can just include the header, and all common variables will be available in the global context.
Thanks guys.
To clarify again, I decided to make 1 single file (where I combine my functions), and include that in every indi, instead of putting those functions one-by-one in all my indis..
how to do that? I mean coding part.

Create an include file i.e. MyVariables.mqh
int var1 = 3; double var2 = 10.2; double func() { return(var1*var2); }
Then in your code (scripts, indicators, EAs):
#include <MyVariables.mqh> void OnStart() { Print(var1); Print(var2); Print(func()); }
Create an include file i.e. MyVariables.mqh
Then in your code (scripts, indicators, EAs):

Hi.
I am building my everyday functions library, so I will include it in all my projects ( I dont know which one I should choose: include or library filetype)...
However, many functions need to use some specific GLOBAL variables from the main indicator....
For example, in my main indicator i have:
double my_Day, my_Session, my_Endtime ......and many different variables..
void OnInit(){
double my_Day= SymbolInfoDouble(......);
double my_Session= SymbolInfoDouble(......);
......and many different declarations..
}
#import "stdlib.ex5"
string MyFunc(bool StartTredline);
#import
and in MyFunc function (inside Library file) I use those variables (my_Session, my_Endtime, and many others).
Is there any way to pass GLOBAL variables directly, without passing them as parameters everytime, like :
MyFunc(StartTrendline, my_Day, my_Session....... and many more)
instead, I called MyFunc(StartTrendline)
and it could read the GLOBAL variables from main indicator?
(In contrary, how can I access global variable, set in library file..)
