how to send email?

New comment

I have the following indicator code. It shows an arrow on the screen when a certain condition exists.

I want to have it send an email when the condition exists AFTER I attach it to the chart.  The problem is that it currently tries to send emails for each occurrence when I attach it.

Can anyone help please ?

Price Bar number 1 is an Inside Bar
Price Bar number 2 is an Inside Bar in relation to Price Bars 3 & 4
The high of Bar 2 is below the high of Bar 3
The low of Bar 2 is above the low of Bar 4

No one knows how to accomplish this?  or is it so simple that I'm just missing it? 
   static datetime alert_bar_time=0;
   //
   //
   if(i==0 && Condition && alert_bar_time!=Time[0])
      {
      alert_bar_time=Time[0];
      Alert("...");
      }

 

 

Use variable names that describe what they are.

Calling your buffer "CrossUp" makes no sense when you are checking for an inside bar 

 

      for (counter=i ;counter<=i+9;counter++)
      {
         AvgRange=AvgRange+MathAbs(High[counter]-Low[counter]);
      }
      Range=AvgRange/10;

 Here you call the sum of the range "AvgRange" and call the average "Range".

It may not matter for simple code, but can be confusing when it gets more complicated.
