[amibroker] Basic line plot referencing earlier Bar - not working

[ozzyapeman]

Hi, hoping someone can chime in on this basic line plot question. I seem
to be having a lot of basic plotting problems lately, on stuff that I am
sure should work.

In this case, all I want to do is draw a line between the current Close
and the Low of 5 bars ago, if the current Close is lower than that Low.

This is what I have, but the lines do not plot. I'm also wondering if I
even need to use looping for this or if I can do it without loops. Any
input appreciated:


SetChartOptions(0, chartShowArrows|chartShowDates);
   _N(Title = StrFormat("{{INTERVAL}} {{DATE}} \n{{VALUES}}",
                        O, H, L, C, V, SelectedValue(ROC(C, 1)) ));

Plot(C, "Close", colorBlack, styleThick|styleDots);
Plot(H, "High",  colorBlue,  styleLine);
Plot(L, "Low",   colorRed,   styleLine);


// Any time that the current Close is lower than the *Low* of 5 bars
ago, then plot a
// red dashed line between those two prices.

fb       = Max(Status("firstVisibleBar"), 5);
lb       = Status("lastVisibleBar");

Low5    = Ref(L, -5);
LineLow  = Null;

for ( i = fb; i < lb; i++ )
{
   if( C[i] < Low5[i] )
   {
    LLow    = LineArray(i, C[i], i-5, Low5[i] );
    LineLow = IIf(!IsNull(LLow), LLow, LineLow);
   }
}

Plot(LineLow, "LineLow", colorRed, styleDashed);
