You are right

I must give more informations if I want to be understood

I hope that this graph is clear enough

The lookback period is usefull to clean the graph from pollution of all the H/L of the data range

Let say on my graph that I estimated that the -4 day is an important top

It could be also the -10 day ( the yellow arrow )

or any lookback (may be maxi 50 days ?)

The Blue/red color for H/L is a way to immediatly see the confluences of the H/L

my last code should do this trick.
all you need to do is to copy my codes in lookback=3 to lookback=4.

It could be also the -10 day ( the yellow arrow )

or any lookback (may be maxi 50 days ?)

The Blue/red color for H/L is a way to immediatly see the confluences of the H/L

if you need addition lookbacks, simply use my original code here:
http://www.traderslaboratory.com/for...html#post63601

this code is for ONE lookback only.
simply apply this indicator to the chart with the lookback at 10,
then you will have the HL lines from 10 days ago.

if you also need to lookback at day 50,
then apply the indicator AGAIN... with lookback at 50.

QED !

additional notes:

if you want to plot current day's high low...
this requires a different routine.

because past day's HL are static,
all you need is to find the HL once and plot the lines.

Current day's HL is a moving target.
Your codes needs to detect and compare current bar's HL
to see if it has made a new HL, then plot the HL lines accordingly.
... and this has to be done for every bar and after every tick.

QED

What does it means ?

[HAL9000]

Quod erat demonstrandum!

If I remember right.

It means something like:

"What had to be shown"
(sorry for my English, I guess I could it better explain in my mother tongue).
It is usually used, behind a successful finished proof.

Of course

QED or CQFD
which was to be demonstrated

English is not my mother tongue too

Here is one of the 3 indicators wich slowed down MC

// The code slows dramatically MC when resizing the scale with the mouse in 1 mn untill it freezezes all the screen during 10 seconds

// HL bar (MC)
// version: beta 0.3
// author: TAMS
// date: 20090426
// license: public use
// description: this indicator draws a trendline 
// at the highest high and lowest low of X days back
// 
// 20090503: modified by aaa for multi-days lookback
// 20090503: TAMS: added different colors for each day
// 20090503: TAMS: added tl extension for lookback=3
// 20090505: aaa:  removed 
//			multi-days lookback  
//			different colors for each day 
//		     added 
//			StartDate
//			tl_setextright (Sneo suggestion)
// The code slows dramatically MC when resizing the scale with the mouse in 1 mn untill it freezezes all the screen during 10 seconds

input:
StartDate(	1090426),
Line.size (	1 	),
Line.style (	2	),
Color.high(	blue	),
Color.low(	red	);

If date this bar >= StartDate then 
begin

	if date <> date[1] then begin
		value1 = tl_new_s(d , time_s , highd(1) , d , time_s , highd(1) );	
		value2 = tl_new_s(d , time_s , lowd( 1) , d , time_s , lowd(1)  );

		tl_setcolor( value1, Color.high );
		TL_SetSize(  value1, Line.size  );
		TL_SetStyle( value1, Line.style );		
	
		tl_setcolor( value2, Color.low  );
		TL_SetSize(  value2, Line.size  );
		TL_SetStyle( value2, Line.style );		
	end;
		tl_setextright(value1, true);
		tl_setextright(value2, true);
end;

Suggestion for working with zero problems

MC has a very good C++ multiprocessoring engines

Actual powered quad CPU + GPU can draw millions of lines in a fraction of a seconds

2 Mo memory is enough... 4 Mo is better and cheap (instead 3,xx Mo is available for programms and 1,xx Mo reseved to the system )

I suggest a C: ghost each week ( C = windows D = your programm )

The system will be clean without virus and You will always have the best of windows performance and security
