Thanks for the code. Any idea how I could modify it in such a way that the indicator can show up and down arrows at the turning points instead of lines ?
Unfortunately I do not know how to insert arrows instead of lines, but the ZigZag indicator is not very reliable, because it often modifies the previous signal, it is as if a trader went back in time and could modify the signals: they would all be rich.
"Since the Zig Zag indicator can adjust its values based on subsequent changes in the underlying plot, it has perfect hindsight into what prices have done. Please don't try to create a trading system based on the Zig Zag indicator - its hindsight is much better than its foresight!"
I have figured out the up and down arrow portion., but there's a unwanted orange zigzag line that I would like to remove. Can some one please tell me which line of code I need to delete to achieve that ?

I have simplified the codes. Can some one please please tell me how I could remove or change the color of the Zigzag line ? The up and down arrows are good enough for me. A million thanks in advance. I've tried to examine each line, but I can't figure it out.

I am able to add these lines to make the unwanted zigzag line black which is the same color as the background. Just wondering if there's a reserved word color for transparent or how I can get a RGB color code to substitute transparent color ?

if condition1 then

var7 = true ;
end;
end ;
end

begin

if var0 <> -1 then

condition1 = var4 >= 0 and var0 <= var1 - RetracePnts ;
if condition1 then
begin
var5 = true ;
var6 = true ;
var4 = -1 ;
end
else
begin
condition1 = var4 = -1 and var0 <= var1 ;
if condition1 then
begin
var5 = true;
var7 = true;

if var5 then
begin
var1 = var0 ;
var2 = Date[1] ;
var3 = Time[1] ;
var5 = false ;
end ;
there is the Reserved word: transparent, but maybe it is only for Tradestation 10, because in my Tradestation 8 it is not there (see image), maybe it is not even in Multicharts.
I wanted to ask you if you can write here the Function of Donchian Channel.
Thank you a lot.
