function NewBar()
	{
	PrevDateTimeNum	= StaticVarGet("DateTimeNum");
	LastDateTimeNum 	= LastValue(DateTime());
	StaticVarSet("DateTimeNum",LastDateTimeNum );
	return PrevDateTimeNum != LastDateTimeNum;
	}

Subject: [amibroker] Detecting New Bar


I use the code below to detect when a new bar is started, so that I process
some indicators only once per bar in order to decrease CPU load.

The code below uses LastValue() function (which is slow). I would like to
replace it with Close[BarCount-1] ..., but can not quite figure out how ...

My concern is that Quick AFL keeps changing the number of bars loaded as
time goes on, so I am not sure what the impact is.

Anyone see a way out?

Thanks

Ara

//Detect New Bar
//Variables: NewBar
//

if (IsNull(StaticVarGet("Lastbar")))
{
StaticVarSet("Lastbar",0);
}

//Detect New bar
//Use to start routines at start of new bar
//
NewBar = False;
if (StaticVarGet("Lastbar")!=LastValue(BarIndex()))
{
NewBar = True;
StaticVarSet("Lastbar",LastValue(BarIndex()));
}
