Watch List Refresh Frequency

[saurmitt]

Hello

I have an EFS which has setComputeOnClose();

When I add this EFS to a watchlist, the EFS seems to be executed multiple times per bar.. Is there a way to configure watchlist so that the EFS executes only once per bar ?

thanks in advance

How did you come to this conclusion?

the EFS code is something like this..

-----------

setComputeOnClose();
setPriceStudy(false);

function main() {
if (getBarState() == BARSTATE_NEWBAR)
{
//some code
//some code
Alert.addToList(getSymbol(),"alpha alert", Color.white, Color.black);
}
}

-------
1) add this EFS to watchlist..
2) edit column and set time interval as 15 mins..
3) open alerts log.. look at the symbol column and time column as the data in the watch list refreshes

for each symbol, there are multiple alerts in the alert log for every 15 minutes duration.. This is making me conclude that the EFS is executed more than once every 15 mins, and hence more than once per bar.. Same EFS when added to a chart generates just one alert per bar

Alex: let me know if you need more info on the above steps

Thanks

As far as I can see the script is executing (and triggering the alert) once only per bar.
As an aside using a check for BARSTATE_NEWBAR is redundant since you already have set the formula to compute on close only

See attached screenshot showing 2 alerts within 1 minute for the same script..

here's the full EFS code for your reference

function preMain(){
setComputeOnClose();
setPriceStudy(false);
}

function main() {

if (getBarState() == BARSTATE_NEWBAR)
{

Alert.addToList(getSymbol(),"alpha alert", Color.white, Color.black);



}
}

Does this prove that the issue is reproducible ? or am i doing something wrong ?

Thanks for pointing out the redundancy.. I had added it just to be double sure..

Please do help resolve the issue..

As I said in my prior reply and as illustrated in the set of screenshots enclosed below your script is executing and triggering the alerts once only per bar at my end
Alex

Image captured after first loading the script



Image captured after the first 15 minute period. As you can see there is only the first set of alerts followed by those at the new 15 minute bar



Image captured after the second 15 minute period. Again the only executions are those at the time a new bar is created

I may know why you are seeing that behavior. That said this is just a guess as you did not provide any pertinent information.
Do you have Hibernation enabled in the Watch List? Also do you have any symbols in that Watch List that are outside of the visible area?
If so keep in mind that any time a symbol is put into - or taken out of - hibernation [by scrolling through the Watch List] the data set for that symbol is refreshed thereby triggering a reload of the script [for that symbol].
Also the data set of any symbol in hibernation is refreshed every 5 minutes again triggering a reload of the script [for that symbol].
Once you disable Hibernation in that Watch List the script will execute once only per bar as I illustrated in my prior reply. Note however that doing this will affect your symbol count [if that is important to you]

Thanks for your reply Alex.. I did have 100+ symbols and many were outside the visible area.. That must have been causing the problem..

How do I disable hibernation in watch list ?

Thanks

found the option to turn off hibernate mode in watchlist menu

You are welcome
If you do not already have it you may want to bookmark the link to the eSignal KnowledgeBase where you can find most of the information on the program (including for example what you inquired about)
