Looking for Working SMTP server for e-mail sending

Robert Gerald Wood, 2022.06.07 14:11

Hi,

I use GMail to send emails, you just have to setup an App Password for Gmail.

Once you have your app password, you setup the email in metatrader as usual, just using the app password instead of your gmail account password.


Hope it helps.

SMTP connection fails

Eleni Anna Branou, 2022.08.18 17:15

Email notifications work fine, check your email MT4/5 settings.


You go to MT4/5 >> Tools >> Options >> Email tab and you fill in the necessary details for your email and server, in order to receive your email notifications. Below is an example of the details that are required and a list of the most popular email providers and their SMTP settings.

  • In the SMTP server field you need to put your email provider’s SMTP address, you can see most of the popular providers below.

  • In the SMTP password field, you need to put your email’s password.

  • In the From and To fields, you need to put your full name a comma and then your email again, for example: John Smith, johnsmith@gmail.com

I am trying to code my system however after compiling it returns the "not all control paths return a value"
----------------------------------
string buyorder()
{
if((iMA(Symbol(),PERIOD_CURRENT,200,0,MODE_SMA,PRICE_MEDIAN,1)-(10*Point))<=iLow(Symbol(),0,1)&&
(iMA(Symbol(),PERIOD_CURRENT,200,0,MODE_SMA,PRICE_MEDIAN,1)+(10*Point))>=iLow(Symbol(),0,1)&&
(((iMA(Symbol(),PERIOD_CURRENT,200,0,MODE_SMA,PRICE_MEDIAN,2)-(10*Point))<=iLow(Symbol(),0,2)&&
(iMA(Symbol(),PERIOD_CURRENT,200,0,MODE_SMA,PRICE_MEDIAN,2)+(10*Point))>=iLow(Symbol(),0,2))
||iLow(Symbol(),0,2)>=iMA(Symbol(),PERIOD_CURRENT,200,0,MODE_SMA,PRICE_MEDIAN,2)))

return("Please_Buy");

}

  2. string buyorder(){  <<<<<<<< function returns a string.
   if(condition) statement;
 <<<<<<<<<<<<<<<<<<<<<<<<<<< what are you returning here?
} <<<<<<<<<<<<<<<<<<<<<<<<<< end of function.

There is no simple way to do that in MQL, you would need to parse the string to identify the operands and operator to apply.

Thank you, Alain, for your reply. Could you please tell me which function I can parse the string ?
