It basically looks for the previous bar with higher high, or lower low than
the current bar, and progresses back till you have the required number of
highs/lows. Eg In my example I am looking for the 3 day CBL, ie the 3rd
higher high, or lower low from the selected bar.
Here are some web refences for it

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.

Inititally it was for the 3 day count back line, but I am endeavouring to
expand on this for finding short term peaks and troughs and some other
thoughts 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 the
moment 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] + " ? ";

Hi Graham,
Can you tell me what you are trying to do? From looking at your code, it
appears that the only elements of LowerLow that can ever get changed are 1,
2 and 3.

Subject: [amibroker] Stepping backwards in loop
I have this formula in a loop but it steps through the values from the
beginning 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 forward
direction.
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
