First, install the Autochartist MetaTrader plugin.

You can download it here
The page also contains some videos and instructions on installing it.
If you already have a live trading account, during installation, select

I got Autochartist through my broker

If it installs, then you all set, and might have access to Autochartist for FREE!
If it tells you
..

your broker is not supported

You will need to sign up for a 14 Day Free Trial account here
On the sign up form, select “I don’t have a broker”
You will receive a confirmation email with a user name and password, as well as a link to try out the Binary Options system.
Once you have your username and password, run the Autochartist MetaTrader Plugin installer again, and this time select:

I have a demo/live subscription directly through www.autochartist.com

It will ask for your username and password.

Be sure to email your broker’s support desk and ask them if they offer Autochartist, or if they plan to offer it in the future. If many people are interested in Autochartist and let them know, your broker may decide to make it available to their clients for FREE!
