Hi all, i understand this is probably a bit of a foolish question, sorry about that ![](https://resources.faireconomy.media/images/emojis/64/1f61e.png?v=15.1)
I see alot of traders, when they post their systems and methods on threads here, attach files (usually .ex4 .mq4 .tpl) of their indicators and methods, when i try to open these files my pc says i do not have a program to open them with yet i have installed Metatrader4. Occasionally i can open then, but in metatrader editor, if anyone could help, how do i bring these indicators and methods up on my metatrader?
Thanks in advance, rob.
