I’m looking for an indicator that automatically shows the last pivot high and low.

Here is a code from another program:

{- Filename: Nico Bakker 4-2 PH&PL -}
var
i,x,y,Cnt : integer;
TheEndofX,TheEndofY : Boolean;

aStart_x: array[0..2000] of integer;
aEnd_x : array[0..2000] of integer;
aPrice_x: array[0..2000] of real;

aStart_y: array[0..2000] of integer;
aEnd_y : array[0..2000] of integer;
aPrice_y: array[0..2000] of real;

begin

with Indicator do
begin
RequiredBars := 10;
NewBand := false;
ScaleRange := srCommon;
end;

for i := firstvalidIndex(High)+ 6 to BarCount - 1 do
begin

if (High[i] < High[i-2]) and (High[i-1] < High[i-2]) and (High[i-2] > High[i-3]) and (High[i-2] > High[i-4])and (High[i-2] > High[i-5])and (High[i-2] > High[i-6]) then
begin
if not TheEndofX then aEnd_x[x]:= i-2;
x := x + 1;
aStart_x[x] := i-2;
aPrice_x[x] := High[i-2];
TheEndofX := false;
end;
if not TheEndofX and (High[i] > aPrice_x[x]) then
begin
aEnd_x[x] := i;
TheEndofX := true;
end;
if i = barcount-1 then
begin
if aEnd_x[x] = 0 then aEnd_x[x] := i;
for Cnt := 1 to x do
begin
with CreateTrendline(Barposition[aStart_x[Cnt]], aPrice_x[Cnt], Barposition[aEnd_x[Cnt]], aPrice_x[Cnt])do
begin
Color := clRed;
Style := lsDash;
end;
end;
end;
if (Low[i] > Low[i-2]) and (Low[i-1] > Low[i-2]) and (Low[i-2] < Low[i-3]) and (Low[i-2] < Low[i-4])and (Low[i-2] < Low[i-5])and (Low[i-2] < Low[i-6]) then
begin
if not TheEndofY then aEnd_y[y]:= i-2;
y := y + 1;
aStart_y[y] := i-2;
aPrice_y[y] := Low[i-2];
TheEndofY := false;
end;
if not TheEndofY and (Low[i] < aPrice_y[y]) then
begin
aEnd_y[y] := i;
TheEndofY := true;
end;
if i = barcount-1 then
begin
if aEnd_y[y] = 0 then aEnd_y[y] := i;
for Cnt := 1 to y do
begin
with CreateTrendline(Barposition[aStart_y[Cnt]], aPrice_y[Cnt], Barposition[aEnd_y[Cnt]], aPrice_y[Cnt])do
begin
Color := clBlue;
Style := lsDash;
end;
end;
end;
end;
end.
