alert.email

[jarrodb]

I have esignal set up to email alerts. When I click on view, alerts and set one up, it will successfully send me an email, but when i code an efs file to send me an email via alert.email("message here") the email never gets sent. I know the smtp server and all the settings are correct since i can recieve the alert email when i manually set it up. Can someone help?

Re: alert.email

Not sure if yours was a typo or not but the function is actually Alert.email() and not alert.email().
Note that Javascript (which is at the foundation of EFS) is a case sensitive language.
If that is not the issue then the reasons could be several and you will need to post your code - or a complete example that illustrates the issue - for someone to be able to determine what the problem may be and to provide a solution

Alert.email()

I did use Alert.email(). That was a typo in my post. I just added a few lines of code below to the previousDaysDailyBars.efs that would test sending an Alert.email(). It doesn't send the email, but when I manually enter an alert the email gets sent Any ideas?

Re: Alert.email()

jarrodb
Alerts are executed only on the current bar (so as to avoid a slew of alerts being triggered on each historical bar as the script loads in a chart). In your code the variable alertTriggered is set to true on the first execution of the script which happens on the first bar as the script loads in the chart hence the condition is no longer evaluated by the time it reaches the current bar. To verify this just add a getCurrentBarIndex() to the debug statement eg

if (alertTriggered == false)
{
   debugPrint(currentPrice);
   Alert.email(getCurrentBarIndex()+"  "+currentPrice);
   alertTriggered = true;
} 

and you will see that the bar index being returned is the one of the first bar on the chart. To resolve this add a condition to your statement that checks that the bar being processed is the current bar eg

if (alertTriggered == false && getCurrentBarIndex() == 0)
{
   debugPrint(currentPrice);
   Alert.email(getCurrentBarIndex()+"  "+currentPrice);
   alertTriggered = true;
} 

and the email alert should work
Hope this helps

Thanks alex. One more question. Does it reload this code everytime a new bar is printed? I have the alertTriggered variable that is set to true once alert goes off because i don't want to receive more than one alert. This forces me to reload the EFS to restart the alert process. Once i set alertTriggered to true, will it stay true once a new bar is printed? If so, how would i get it to keep the value of alertTrigggered?

Yoiu can reset the alertTriggered flag back to false at every new bar by adding the following code at the beginning of the main function

if(getBarState()==BARSTATE_NEWBAR){
    alertTriggered = false;
} 

This way the flag gets reset [without the need to reload the script] and if the condition evaluates to true it will trigger the alert once only on that bar

The probelm with that is that if that the same alert will be triggered every bar if the condition is met. I want the alert to trigger once and then require me to reload the script or do "something" to reset it other wise i will keep getting alerts for the same condition each time a new bar prints. any ideas?? Is there a way to make that variable a global?

The alertTriggered variable is already a global variable as it is declared outside of the main function.
There are several ways to accomplish what you want. One way would be to define a condition that evaluates to true only on the first bar and not on the subsequent bars. For example
if(current_AvgA > current_AvgB && previous_AvgA < previous_AvgB
is true only on the first bar in which average A is above average B whereas
if(current_AvgA > current_AvgB)
is true on every bar in which average A is above average B.
Another way would be to reset the alertTriggered variable to false only when the condition is no longer true or when some other condition occurs
If you run a search through this forum you will find many scripts and/or code examples that trigger alerts based on a variety of conditions.
