Please note that you can install the indicators on as many PC’s as you wish, but the indicators will only work if the MT4 trading account is the same on each machine. This gives you the option to install them on a laptop and desktop for example for travelling etc. If you want to install the indicators on two different accounts and run them simultaneously, then you will need to purchase a second user licence and create a second user account. Second and subsequent user licences are available at a 50% discount from the first.
