MT4 SCRIPT

Hello there!

I'm looking for someone who can help me out with scripting a few things for me.  I think these are relatively simple to produce, but I can't seem to get started.  To start with, I just need the following:

1. I need a dotted vertical line script that I can drag and drop manually to my MT4 Chart Window.
2. Style: Turquoise.  Description: CONFIRMATION.  Visualization: Show on all the timeframes.
3. I would like the Description to display on on the MT4 Chart Window.
4. I would like to be able to learn how to duplicate the script myself to show different styles, and descriptions.

I use Alpari, through Parallels Desktop, and I think that version only accepts .mql4 files, but I also use alpari through PLAY ON MAC, which seems to only use .ex4 files.

Any help and advice, would be greatly appreciated. 

Best regards,

 Andrew
