Re: [amibroker] Detecting New Bar

["Ara Kaloustian" <ara1@xxxxxxxxxx>]

Thanks Herman

I was trying to eliminate use of LastValue(), but the structure you provided
should allow me to do that.
Putting it in a function is an extra bonus.

I beleive this modification should work.

> function NewBar()
> {
LastDateTimeValue = DateTime();

> PrevDateTimeNum   = StaticVarGet("DateTimeNum");
> LastDateTimeNum   = LastDateTimeValue[BarCount-1];
> StaticVarSet("DateTimeNum",LastDateTimeNum );
> return PrevDateTimeNum != LastDateTimeNum;
> }
