Graham,
I have heard the term Countback Line but I dont
know what it does. If you want to try describing how it works, I could maybe
take a stab at it.

Subject: RE: [amibroker] Stepping
backwards in loop
SteveInititally it was for the 3 day count back line,
but I am endeavouring toexpand on this for finding short term peaks and
troughs and some otherthoughts I have for some systems once I get it
working. When I plot it the lines start at the first occurrence of the
particular low(or high) price. Here is the whole picture of the formula I
am using at themoment as I try to get it working the way I am
wanting.// INDICATOR //Count Back Line //by Graham Kavanagh 22
Sep 2003//Plot(C, "Close", colorBlack,
styleBar+styleNoLabel);period = 3;Bar =
SelectedValue(BarIndex());LastBar = LastValue(BarIndex());start =
Lastbar-bar;LowerLow[0] = SelectedValue(L);for ( j=1;
j<=period; j++ ){for ( i=1 ; i < Lastbar ; i++ ){
if ( L[i] < LowerLow[j-1] ) { LowerLow[j] =
L[i]; }}}Lowerline =
SelectedValue(LowerLow[period]);BarL = ValueWhen(
L==Lowerline, BarIndex(), 1 );CBLow = IIf( BarIndex()>=BarL,
Lowerline, Null );Plot(CBLow, EncodeColor(colorRed)+ "3 day CB Low",
colorRed, styleDots);//Plot(SelectedValue(L), EncodeColor(colorRed)+
"Bar Low", colorRed,styleLine);HigherHigh[0] =
SelectedValue(H);for ( j=1; j<=period; j++ ){for ( i=1; i
<Bar ; i++ ){ if ( H[i] > HigherHigh[j-1] )
{ HigherHigh[j] = H[i];
}}}Higherline =
SelectedValue(HigherHigh[period]);BarH = ValueWhen(
H==Higherline, BarIndex(), 1 );CBHigh = IIf( BarIndex()>=BarH,
Higherline, Null );//Plot(SelectedValue(H),
EncodeColor(colorGreen)+ "Bar high",
colorGreen,styleLine);Plot(CBHigh, EncodeColor(colorGreen)+ "3 day CB
High", colorGreen,styleDots);Title = Name() + " " + Date() + " / "
+ BarCount + " / " + bar + " / " +Lastbar + " ? "+ L[0] + " ?

From looking at your code, itappears that the only elements of LowerLow
that can ever get changed are 1,2 and 3.Steve----- Original

September 22, 2003 8:58 PMSubject: [amibroker] Stepping backwards in
loopI have this formula in a loop but it steps through the values
from thebeginning of the data rather than from the end. I have tried
reversing the line " for ( i=1; i < bar ; i++ ) " to " for
(i=bar; i > 0 ; i-- ) " but stills seems to check the bars in the
forwarddirection. All I want to do is go back from the selected (or
last) bar. Help appreciated. period = 3;Bar =
SelectedValue(BarIndex());LastBar = LastValue(BarIndex());start =
Lastbar-bar;LowerLow[0] = SelectedValue(L);for ( j=1;
j<=period; j++ ){for ( i=1; i < bar ; i++ ){ if (
L[i] < LowerLow[j-1] ) { LowerLow[j] =
L[i]; }}}Cheers,Graham<A
