There are a few places to find your Metatrader account number. However, the best place to copy your account number from (to paste later) is in Tools > Options > Server (tab) > Login (field):
In the IfStats.com user interface, go to the broker account page (in the top navigation bar) and click the Create New Broker Account link:
Paste the Metatrader broker account number (from step 1) you want to import into IfStats.com. IMPORTANT: The broker account number in IfStats.com must match your account number in Metatrader (or your account history will not import).
Go to MT4 and choose Tools > Options > Expert Advisors (tab) and check the box to enable Allow WebRequest for listed URL. In the box below that, double click the green plus (+) icon and add https://api.ifstats.com to the approved URLs.
Unzip (Extract) the IfStats.zip file and Copy the IfStats.ex4 EA file to your Metatrader Experts folder. You can get to the Experts folder by opening your Metatrader app and go to File > Open Data Folder > MQL4 (folder) > Experts (folder).
Right click Expert Advisors in the Metatrader Navigator interface and choose Refresh (or simply close and open your Metatrader app).
Open any currency pair chart, right click IfStats, choose Attach to Chart:
When the settings for the EA pop up, enter your email address that you registered with IfStats.com and choose Ok.
After five minutes, go check your IfStats account to see your orders imported.
