Email Alerts
Your expert advisor can alert you by email about placed trades, potential trade setups and more. The
function SendMail() will send an email with the subject and body of your choice to the email
address that is listed in the Tools – Options dialog under the Email tab.
In the Email tab, you must first specify the SMTP mail server with port number – for example:
mail.yourdomain.com:25 -- along with a username and password, if required. Check with your ISP or
hosting provider for this information.
You can use any email address in the From field. The To field is the email address to send messages
to. Be sure to check the Enable setting at the top to enable the sending of messages.
The SendMail() function has two arguments: the first is the subject line of the email, and the
second is the contents of the email itself. You can use newlines, escaped characters, variables and
constants within the body of your email.
