[amibroker] Help!! simple looping problem???

[christianvost]

Hi, This is probably an easy one, but I'm struggling with looping through 
arrays in afl. Have a look at the simple code below.  
( copy+paste into editor then drag into price pane ).

//Resline.afl
//
OneHigh = H;
TwoHigh = Ref(H,-1);
ThreeHigh = Ref(H,-2);
ResLine = ValueWhen( ThreeHigh < TwoHigh AND TwoHigh > OneHigh,TwoHigh,1);
Plot(ResLine,"ResLine", ParamColor( "Color", colorCycle ), ParamStyle("Style") 
);

I tried to write a 'for,if' loop to replace the previous code, but it's not 
working. Can anyone correct the following code sample for me please???  
Thank-you to all.

ResLine[0] = 0;

for(i=2; i<BarCount; i++)
{
 if(H[i-2] < H[i-1] AND H[i-1] > H[i]) 
        {
         ResLine = H[i-1];
        } 
//Plot(ResLine,"ResLine",colorRed, styleLine|styleThick); //inside loop plots 
multiple lines
}
Plot(ResLine,"ResLine",colorRed, styleLine|styleThick); //outside loop plots 
single line (most recent value when condition is met)
