In the DisplayAlert() function:
void DisplayAlert(string message, int shift) { if(shift <= 2 && Time[shift] != lastAlertTime) { lastAlertTime = Time[shift]; Alert(message, Symbol(), " , ", Period(), " minutes chart"); SendMail(message, Symbol(), " , ", Period(), " minutes chart"); } }

sharky23:
thanks but its telling me
'SendMail' wrong parameters count
?
Sorry, should be
SendMail(Symbol()+" minutes chart",message);
Thank you the option is now available on th indicator..now i just need the comand for the alert of the MACD signal line with the MACD line for crossover alerts to the email -_-"
