Create a Variable based on Symbol

New comment
 

Hi there.

I am new to mql4 programming and been read some books and tutorials but the easiest way to get the things done is with your precious help.

I need to create a variable (in fact a global variable) that is based on symbol where the indicator is attached.

That way I will be able to use the indicator in several pairs without having to re-code the indicator for each pair.


The idea is:

- Create/Check/Set value of a variable based on currency symbol.


For instance: The indicator is on EUR-USD pair.

The indicator code creates a global variable named "PAIR"_variable_name. In this case EURUSD_variable_name.

If attached on USD-CHF, should be "PAIR"_variable_name. In this case USDCHF_variable_name.


Thank you very much

Symbol() returns the name of the pair on the chart the indicator/script/EA is attached to
