 The previous example shows the promise of this language. However, it would be exhausting to have to create one file per ticker of interest. And this is why we allow the user to create arguments within a script that will be populated at the time of execution, which provides a more efficient experience.

 In addition, OpenBB accepts the creation of variables inside the script. This can be useful when the user utilizes a ticker as a benchmark/reference, and therefore instead of having to change the ticker of interest in multiple places they can just change the variable. Example of script below:

 The previous input variables are very powerful and can be used for a wide range of functionalities - one of them being dates. E.g. a typical example could be running a script routine with `exe myscript -i TSLA,2010-01-01` where `$ARGV[1]=2010-01-01` and thus it denotes an instant of time.

 To be a powerful scripting language, we needed to introduce the concept of foreach loops. These allows to iterate through a list of variables / arguments to execute a sequence commands.
