timing procedures

[Chris747]

Howdy folks...
I'm having a difficult time trying to get a procedure to run once every 15 seconds and then wait for another 15 seconds to run again and have not been able to find a reliable solution....any help would be appreciated. So far I've been doing it along these lines....

////Premain
function preMain( )
{
setPriceStudy( true );
setColorPriceBars(true);
var today = new Date();
gcheckSeconds = today.getSeconds() + 15;
}

///Main
if(today.getSeconds() >= gcheckSeconds)
{
call procedure here
gcheckSeconds = today.getSeconds() + 15;
if(gcheckSeconds > 60){
gcheckSeconds = 15;
}
}


the procedure is sometimes called 2, 4, 7...maybe 15 times before it gets reset to wait 15 seconds before running again. I believe the problem to be because the script is running on ticks and not seconds, per se. Any help would be much appreciated....
Thanks
Chris

Hi Chris,

I have not tested this, but it should work

//outside preMain and main
var previous_time = 0;


////Premain
function preMain( )
{

}

///Main
var today = new Date();
var current_time = today.getTime()/1000;
if (current_time > (previous_time +15)){
    previous_time=current_time;
    
    call procedure here
} 

With regards to it working **exactly** at 15 second intervals, keep in mind that main will only be executed every tick. Therefore, the conditional will be true the first tick that occurs 15 seconds after it had previously been satisfied.
