this the program of my indicator and i want to receive 1 or 2 mails per bar, no more.
I asked in ninjatrader forum and they told me this:

Declare an integer variable. Have this variable reset to 0 on the first tick of the bar. Where you have the alert / email, add a condition that checks the value of the integer variable being under how many alerts / emails you want. Increment the integer variable each time the alert / email is triggered.
In your alert call, be sure to set the rearmSeconds to a value above 0, and to a comfortable level.

but i don' t know how to do this.

What is the exact logic to fire the email ?

In big lines what you need to do :

1) you need to make sure your indicator is called not only on bar close, if you want the logic to be triggered more than once a bar (onbarclose = false)
2) you will have to keep track and see if a new bar was formed
3) upon trigger condition create email (sendmail) and put a flag (maildone =1)
4) reset the flag on a new bar (maildone =0)

hope this helps you

this the program of my indicator and i want to receive 1 or 2 mails per bar, no more. I asked in ninjatrader forum and they told me this: ...

The code provided seems to be the Ninja generated part, not the indicator itself: no Initialize(), no OnBarUpdate(), ...
We can't do anything without the source, the code provided here is useless.
