Drawing Trade Data Labels in Pine

g'day Traders welcome back to another
video in this video we're going to be
answering another student question from
the Mastery course this student wants to
draw labels above closed trades in the
strategy tester that display information
about the trade such as the profit and
loss on the trade the opening price and
time the closing price and time
Etc so this information should be
valuable for all of you guys out there
who are making strategy scripts and want
to debug your script or just get more
information out of the strategy tester
on a trade by trade basis so stick
around for that but before we do that I
want to give a shout out to a student of
the Mastery course and a Trader who has
become a friend in pen pal of mine his
name is Mark and his online Alias is
deep wave Trading
one second I think my cat is having a
little bit of a nervous breakdown and
Mark has gone through the Mastery course
and has now gone on to make his own
YouTube channel and now I can't take
credit for his uh success as a Trader
obviously that is all him all the work
he has put in but I'm really honored and
proud to have had a student come through
the Mastery course and now go out on
their own and start making their own
educational content on the subject of
system development and back testing
which is a subject that if you haven't
realized by now is very dear to my heart
and very important to me because that's
what makes me my speculation profits if
it wasn't for back testing I wouldn't be
a profitable Trader and back testing is
only one part of the equation system
development is a whole world of its own
so system development and back testing
processes and techniques and tips is
valuable and important to you then I
definitely recommend you go and check
out his channel it's brand new obviously
he doesn't have many subscribers yet
which is why I'm giving him this shout
out he only started this channel two
weeks ago but he does deserve your
attention if you're interested in the
subject he is a phenomenal presentator I
think that's what word he's great at
presenting this information which is
quite complex and advanced he has a
great way of explaining this information
in a way where he can break down these
complex subjects into easy to understand
information that even the most Layman of
Traders can understand and Implement
into their own trading there'll be a
link below in the pinned comment and in
the video description to Mark's Channel
please go and check it out go and
support him he's a great guy and a
phenomenal Trader now with that said
let's jump into the pine editor and
answer another question
the student is trying to add a label to
their strategy script that displays the
entry price the exit price the open time
and the close time timestamp and the
profit of each trade that the script
takes but they're running into an issue
here's a screenshot of their issue so
you can see the open price is according
to the student accurate and so is the
open time but the closing price the
closing time
obviously this is not possible that the
closing time would be before the opening
time when I look at the code here
there's a couple of issues that are
causing the problems here and so let me
show you guys how to add open times
close times open prices close prices
based on the inbuilt strategy variables
this is obviously quite a useful tool
for debugging and back testing so yeah
let's jump into the charts so here I am
with a really simple moving average
crossover script strategy added to my
chart the strategy is not important so
we're not going to address that today
what we are going to address is all of
this code here so this is the code that
I've adapted to more accurately display
our open price closing price open time
close time and now profit so you can see
our profit here was negative 1700 if I
open the strategy tester and go to list
of Trades
um you can see here
same number so
what did I do differently in my code
compared to the original code well the
original code references two different
data sources from the inbuilt strategy
functions so the first one the
Enterprise references open trades and
the exit price references closed trades
now this is these are two separate lists
open trades obviously contains all the
currently open trade data closed trades
contains all closed trade data now if
you want to monitor an open position
then you will need to reference this
list of Trades and the open this is kind
of like an array and so each time you
open a new trade the old trade was
obviously closed and so unless you have
multiple trades open zero is always
going to reference the currently open
trade if you have more than one trade
open zero would be the first trade that
was opened to uh one would be the sorry
zero would be the first trade that was
open one would be the second trade that
was open two would be the third trade
that would open Etc
but with closed trades this holds all of
the previously closed trades this is
what you want to reference if you are
trying to draw trade result data so the
results of your trades so what I've done
is I've just changed all of the open
trades to close trades so we're
referencing the closed trades list
instead of the open trades list that
keeps everything consistent so that when
a trade closes we are referencing the
opening price server hover over this bar
the opening price is 2086 same as that
the date is Wednesday 26th of October
26th of the 10th 22.
the close time is this bar here and that
is Wednesday the 9th of November 9th
November 22 and the profit I already
showed you that so this is accurately
displaying the closed trade data just to
quickly replicate this student's code I
added a truncate function that does
nothing it just Returns the number you
pass into it go and check out my library
lesson if you want to see how to
truncate numbers down to a certain
amount of decimal places in this case
they are trying to truncate this number
to four decimal places my script doesn't
do that just to save time I didn't
bother adding that in but if you wanted
to add that in go and check out my
library lesson Zen Library lesson that
contains the code on how to truncate a
number but the important thing here to
mention or to to draw your attention to
is our Enterprise is set to
strategy.closed trades we're referencing
the closed trades list and we're
referencing the entry price and then we
need to pass in an array index remember
in Pine script and most programming
languages if not all arrays start
counting from zero so the first element
in a in an array is the zero element the
final element in an array the ID the
index of that element is equivalent to
the total size of the array so in this
case we're referencing the closed trades
number this is how many
um
trades were closed by The Script
then we need to subtract one from this
if we don't do that then we're
referencing an array index that doesn't
exist and our price here will be n a as
you can see there Nan not a number so we
need to reference the total size of the
array minus one if you wanted to
reference the very very first trade that
your script ever took you'd put zero in
here so if I save that these numbers
will show the opening and closing price
of the very first trade on my chart so
if I jump to that right now
the first opening trade here the opening
price is two four five three four
two four five three four let me undo
that and then there's a bunch of code
here that's specific to the student
script the only other thing I'll draw
your attention to is the label code here
so I'm declaring a new persistent label
a VAR label when my position size on the
current bar is not equal to the position
size on the previous bar that means we
closed a trade by definition or we
opened a new trade what I should
probably do here is change this to
strategy.close trades not equal
strategy.closed trades on the previous
bar since we're dealing with closed
trade data that would make more sense so
that's still working fine so when the
current bars closed trades number is not
equal to the previous bars closed trades
number that means we just exited a trade
and we display a new label and this
label is drawing on the current bar
index on the bars low and the text of
the label is set here so we have the
Enterprise and the exit price open time
close time now to get the open time and
close time we are formatting the text
with this time stamp format and we are
referencing the strategy.closed trades
list again same as here
but instead of the entry and exit price
we are referencing the entry and exit
time
and we still need to pass in the same
index of that trade we want to reference
in this case it's the final trade in our
list that gives us our final entry time
Final Exit time final entry price Final
Exit price of the final trade the script
took and then finally we have our profit
which is again
strategy.closedtrades.profit and we pass
in the trade index the final trade in
the list and that's it
um down here I this should be changed as
well to close to trades
uh
save that and now that will show the
appropriate tooltip
for the position size of that closed
trade in this case that was 1.08
Bitcoin if you wanted to reference open
trades on currently open bars you need
to change all of these to say open
trades
and this as well obviously
but it makes more sense to me that you
would want to track closed trades data
in your strategy script so I'll leave
this as it is and I'll leave the source
code to this part of the script below
and you can pretty much copy and paste
this into any script one thing I will
mention is that if you want to draw the
label on every single
closed trade on your chart there is a
limit to how many labels you can have on
your chart at any given time that's why
I delete all the previous ones and only
show the latest one but if you wanted to
display a label on every closed trade
this is how you would do it so you want
to declare a new label every time you
create one if I save that code we should
get more labels drawing here there we go
you see what I mean it's pretty pretty
cluttered
so oh that's interesting it used to be
that panscript would display x amount of
labels in the beginning and then they
would just stop drawing and so on your
latest
price action there'd be no labels
because you used up your maximum label
count early on it looks like they've
changed that so it deletes the old
labels first and leaves the latest
labels on your chart so you don't
necessarily need to delete them if you
don't want to assuming you're
comfortable with all this clutter
um obviously you can format the labels
to be smaller the text to be smaller the
color to be blend in better whatever you
want to do but anyway that's it for this
lesson I'll leave the video here so that
you can see the changes I made to
display the label on every single trade
if you want to adapt the source code
below the video and I'll speak with you
in the next lesson take care and good
luck with your training
