[amibroker] PnF - Line Up and Line Down

["tomczykd" <tomczykd@xxxxxxxxx>]

Hello,

I use PnF made by Graham Kavanagh  17 Apr 2004 (http://www.amibroker.com/library/formula.php?id=348).
In this AFL we have LineUp and LineDown when we select value.

LineUp = LineArray( SelectedValue(BarIndex()), SelectedValue(L), SelectedValue(BarIndex())+1, SelectedValue(L)+box, 1, 0 );
Linedown = LineArray( SelectedValue(BarIndex()), SelectedValue(H), SelectedValue(BarIndex())+1, SelectedValue(H)-box, 1, 0 );
Plot(IIf(SelectedValue(PFC<PFO),Lineup,Null), "Line", colorGreen, styleLine + styleNoLabel + styleNoRescale);
Plot(IIf(SelectedValue(PFC>PFO),Linedown,Null), "Line", colorBrown, styleLine + styleNoLabel + styleNoRescale);

How I can change the Line Up or Line Down non as SelectedVelue(BarIndex())? I would like to have this Line Up od Line Down we I start PnF. In this case the chart should shows me all Line Up and Line Down automaticly from par example 10 periods?
In this case I would have the trendlines UP dna DOWN.
Best regards.

Dominik
