A personal version of Symbol Changer
Quite self-explanatory, just added a "symbol changer - slave" indicator to be added to other charts to apply the same currency change like in the example above with an Alien template.

- "v" show/hide button.
- insert "*" in parameters currency list to create a new line.
- possibility to play a sound when a button is pressed.

Please excuse the poorly written code, I am just a beginner.
