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] + " ? ";
Cheers,
Graham

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
