Using List and Map to sort highs and Lows [SOLVED]

On a 1 min chart/ No IOG
We would like to:
find if the highest high occurred on the 1st or 10th bar (i.e. in the first or tenth minute).

if the highest high occurred on bar 1, use the second highest high (providing it does not occur on the 10th bar). If the second highest high occurred on the 10th bar, use the 3rd highest high.

if the highest high occurred on bar 10, use the second highest high (providing it does not occur on 1st bar). If the second highest high occurred on the 1st bar, use the 3rd highest high.

if the highest high occur in bar 2 to 9 then use that as the highest high.

repeat above for finding lowest low.

what is the best way to do the above: arrays or elc list/maps?
And if using ELC what is the best approach to use for this?
Using ELC list and maps:

Code: Select all

variables: 

min_low(0),

min_high(0),

min_bar_count(0);



//create bar counter that increments on date change from 1 to 10

if date <> date[1] then begin

min_bar_count = 1;

end;

if date = date[1] and min_bar_count >= 1 and min_bar_count <= 9  then begin

min_bar_count = min_bar_count[1] + 1;

//min_bar_count += 1;

end;



//reset counter to zero after bar10

if date = date[1] and  min_bar_count[1] = 10  then begin

min_bar_count = 0;

end;

Code: Select all

vars: min_bar_high(MapNN.New), min_bar_low(MapNN.New);

vars: list_high(ListN.New), list_Low(ListN.New);;



value1 =ListN.PushBack(list_high, high);

value1 =ListN.PushBack(list_low, low);



value1 =ListN.Sort(list_high, false);

value1 =ListN.Sort(list_low, true);

Would you now use a List sort by map? If so how?

many thanks for advice/help with this.

We would like to:
find if the highest high occurred on the 1st or 10th bar (i.e. in the first or tenth minute).

If you want to achieve this (which might be something else than your code suggests), there is no need to use a list or array.

For example:

Code: Select all


Variables:

	highOfDay(0),

	barNumOfHigh(0),

	startingBarNum(0);



once cleardebug;

	

// Reset variables

if (Date <> Date[1]) then begin 



	highOfDay = 0;

	barNumOfHigh = 0;

	startingBarNum = CurrentBar;

	

end;	



if (BarStatus(1) = 2) then begin 



	// Calculcate variables

	if (High > highOfDay) then 

		barNumOfHigh = CurrentBar - startingBarNum + 1;



	highOfDay = MaxList(highOfDay, High);



	// Verify

	Print(FormatTime("HH:mm", eltimetodatetime(time)),

		" High of day: " + NumToStr(highOfDay, 5) + ", bar of day: " +

		NumtoStr(barNumOfHigh, 0));



end;

many thanks for reply JoshM. You're right, no need for lists or arrays to achieve this.
much appreciated.
