[amibroker] array processing vs loop processing

[schnitt_tt]

Hi,

the follow code in Array processing shows a red down triangle if a gap
appears.

it_gap     = GapDown();
PlotShapes( IIf( it_gap,  shapeDownTriangle , shapeNone ), colorRed );

I tried to do this with loop processing:

it_gap     = GapDown();
for( i = 1; i < BarCount; i++ )
{
      if( it_gap[i] == True )
    {
       PlotShapes(   shapeDownTriangle , colorGreen );
     }
     else
     {
        PlotShapes(   shapeNone , colorRed );
     }
}

any Idea why this doesn`t show the patterns ... ?
Are their any Functions that I can`t use while looping ??

thx for answering
