log.info() - 5 Exampleslog.info() is one of the most powerful tools in Pine Script that no one knows about. Whenever you code, you want to be able to debug, or find out why something isnโt working. The log.info() command will help you do that. Without it, creating more complex Pine Scripts becomes exponentially more difficult.
The first thing to note is that log.info() only displays strings. So, if you have a variable that is not a string, you must turn it into a string in order for log.info() to work. The way you do that is with the str.tostring() command. And remember, it's all lower case! You can throw in any numeric value (float, int, timestamp) into str.string() and it should work.
Next, in order to make your output intelligible, you may want to identify whatever value you are logging. For example, if an RSI value is 50, you donโt want a bunch of lines that just say โ50โ. You may want it to say โRSI = 50โ.
To do that, youโll have to use the concatenation operator. For example, if you have a variable called โrsiโ, and its value is 50, then you would use the โ+โ concatenation symbol.
EXAMPLE 1
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
//@version=6
indicator("log.info()")
rsi = ta.rsi(close,14)
log.info(โRSI= โ + str.tostring(rsi))
Example Output =>ย
RSI= 50
Here, we use double quotes to create a string that contains the name of the variable, in this case โRSI = โ, then we concatenate it with a stringified version of the variable, rsi.
Now that you know how to write a log, where do you view them? There isnโt a lot of documentation on it, and the link is not conveniently located.ย
Open up the โPine Editorโ tab at the bottom of any chart view, and youโll see a โ3 dotโ button at the top right of the pane. Click that, and right above the โHelpโ menu item youโll see โPine logsโ. Clicking that will openย that to open a pane on the right of your browser - replacing whatever was in the right pane area before. This is where your log output will show up.ย
But, because youโre dealing with time series data, using the log.info() command without some type of condition will give you a fast moving stream of numbers that will be difficult to interpret. So, you may only want the output to show up once per bar, or only under specific conditions.ย
To have the output show up only after all computations have completed, youโll need to use the barState.islast command. Remember, barState is camelCase, but islast is not!
EXAMPLE 2
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
//@version=6
indicator("log.info()")
rsi = ta.rsi(close,14)
if barState.islastย
log.info("RSI=" + str.tostring(rsi))
plot(rsi)
However, this can be less than ideal, because you may want the value of the rsi variable on a particular bar, at a particular time, or under a specific chart condition. Letโs hit these one at a time.
In each of these cases, the built-in bar_index variable will come in handy. When debugging, I typically like to assign a variable โbixโ to represent bar_index, and include it in the output.
So, if I want to see the rsi value when RSI crosses above 0.5, then I would have something like
EXAMPLE 3
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
//@version=6
indicator("log.info()")
rsi = ta.rsi(close,14)
bix = bar_index
rsiCrossedOver = ta.crossover(rsi,0.5)
if rsiCrossedOver
log.info("bix=" + str.tostring(bix) + " - RSI=" + str.tostring(rsi))
plot(rsi)
Example Output =>ย
bix=19964 - RSI=51.8449459867
bix=19972 - RSI=50.0975830828
bix=19983 - RSI=53.3529808079
bix=19985 - RSI=53.1595745146
bix=19999 - RSI=66.6466337654
bix=20001 - RSI=52.2191767466
Here, we see that the output only appears when the condition is met.
A useful thing to know is that if you want to limit the number of decimal places, then you would use the command str.tostring(rsi,โ#.##โ), which tells the interpreter that the format of the number should only be 2 decimal places. Or you could round the rsi variable with a command like rsi2 = math.round(rsi*100)/100 . In either case youโre output would look like:
bix=19964 - RSI=51.84
bix=19972 - RSI=50.1
bix=19983 - RSI=53.35
bix=19985 - RSI=53.16
bix=19999 - RSI=66.65
bix=20001 - RSI=52.22
This would decrease the amount of memory thatโs being used to display your variableโs values, which can become a limitation for the log.info() command. It only allows 4096 characters per line, so when you get to trying to output arrays (which is another cool feature), youโll have to keep that in mind.
Another thing to note is that log output is always preceded by a timestamp, but for the sake of brevity, Iโm not including those in the output examples.
If you wanted to only output a value after the chart was fully loaded, thatโs when barState.islast command comes in. Under this condition, only one line of output is created per tick update โ AFTER the chart has finished loading. For example, if you only want to see what the the current bar_index and rsi values are, without filling up your log window with everything that happens before, then you could use the following code:
EXAMPLE 4
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
//@version=6
indicator("log.info()")
rsi = ta.rsi(close,14)
bix = bar_index
if barstate.islast
log.info("bix=" + str.tostring(bix) + " - RSI=" + str.tostring(rsi))
Example Output =>
bix=20203 - RSI=53.1103309071
This value would keep updating after every new bar tick.
The log.info() command is a huge help in creating new scripts, however, it does have its limitations. As mentioned earlier, only 4096 characters are allowed per line. So, although you can use log.info() to output arrays, you have to be aware of how many characters that array will use.
The following code DOES NOT WORK! And, the only way you can find out why will be the red exclamation point next to the name of the indicator. That, and nothing will show up on the chart, or in the logs.
// CODE DOESNโT WORK
//@version=6
indicator("MW - log.info()")
var array rsi_arr = array.new()
rsi = ta.rsi(close,14)
bix = bar_index
rsiCrossedOver = ta.crossover(rsi,50)ย
if rsiCrossedOver
ย ย array.push(rsi_arr, rsi)
if barstate.islast
ย ย log.info("rsi_arr:" + str.tostring(rsi_arr))
ย ย log.info("bix=" + str.tostring(bix) + " - RSI=" + str.tostring(rsi))
plot(rsi)
// No code errors, but will not compile because too much is being written to the logs.
However, after putting some time restrictions in with the i_startTime and i_endTime user input variables, and creating a dateFilter variable to use in the conditions, I can limit the size of the final array. So, the following code does work.
EXAMPLE 5
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
// CODE DOES WORK
//@version=6
indicator("MW - log.info()")
i_startTime ย ย ย ย = input.time(title="Start", defval=timestamp("01 Jan 2025 13:30 +0000"))
i_endTime ย ย ย ย ย = input.time(title="End", defval=timestamp("1 Jan 2099 19:30 +0000"))
var array rsi_arr = array.new()
dateFilter = time >= i_startTime and time <= i_endTimeย
rsi = ta.rsi(close,14)
bix = bar_index
rsiCrossedOver = ta.crossover(rsi,50) and dateFilter // <== The dateFilter condition keeps the array from getting too big
if rsiCrossedOver
ย ย array.push(rsi_arr, rsi)
if barstate.islast
ย ย log.info("rsi_arr:" + str.tostring(rsi_arr))
ย ย log.info("bix=" + str.tostring(bix) + " - RSI=" + str.tostring(rsi))
plot(rsi)
Example Output =>
rsi_arr:
bix=20210 - RSI=56.9030578034
Of course, if you restrict the decimal places by using the rounding the rsi value with something like rsiRounded = math.round(rsi * 100) / 100 , then you can further reduce the size of your array. In this case the output may look something like:
Example Output =>
rsi_arr:
bix=20210 - RSI=55.6947486019
This will give your code a little breathing room.
In a nutshell, I was coding for over a year trying to debug by pushing output to labels, tables, and using libraries that cluttered up my code. Once I was able to debug with log.info() it was a game changer. I was able to start building much more advanced scripts. Hopefully, this will help you on your journey as well.

JavaScript-style Debug ConsoleThis library provides a JavaScript-style debug console to Pine Coders. It supports the most commonly used utilities from the WHATWG Console Standard including the following:
โโข console.log
โโข console.debug
โโข console.info
โโข console.warn
โโข console.error
โโข console.assert
โโข console.count
โโข console.countReset
โโข console.group
โโข console.groupEnd
โโข console.clear
In addition to the WHATWG standard, this library also supports the following methods:
โโข console.show
โโข console.hide
FEATURES
โโข Follows the WHATWG Console Standard, which is widely adopted by all major JavaScript runtimes including browsers and Node.js.
โโข Provides an out-of-box UI with pre-configured theming, ensuring a clean and professional-looking console.
โโข Allows for easy UI customizations to fit your personal preferences.
โโข Has extremely simple import and initialization, making it easy to integrate with your existing codebase.
USAGE
1. Import this library:
import algotraderdev/Console/1
2. Initialize the console object:
var console = Console.new()
// You can also specify optional params to customize the look & feel.
var console = Console.new(
position = position.bottom_right,
max_rows = 50,
width = 0,
text_size = size.normal,
background_color = #000000CC,
timestamp_color = #AAAAAA,
info_message_color = #DDDDDD,
debug_message_color = #AAAAAA,
warn_message_color = #FFEB3B,
error_message_color = #ff3c00)
3. Use the console object to debug your code. Here are some examples:
// Basic logging
console.log('hello world!') // prints 'hello world'
console.warn('warn') // prints 'warn' in yellow
console.error('error') // prints 'error' in red
console.clear() // clears the console
// Assertion
console.assert(a.isEmpty(), 'array should be empty') // prints 'assertion failed: array should be empty' if the array is not empty
// Counter
console.count('fooFunction') // prints 'fooFunction: 1'
console.count('fooFunction') // prints 'fooFunction: 2'
console.countReset('fooFunction') // resets the counter
console.count('fooFunction') // prints 'fooFunction: 1'
// Group
console.log('A')
console.group()
console.log('B')
console.group()
console.log('C')
console.log('D')
console.groupEnd()
console.log('E')
console.groupEnd()
console.log('F')
// prints
// A
// โโB
// โโโโC
// โโโโD
// โโE
// F
// Hide and show
console.hide()
console.show()

A library of many helper methods, plus a comprehensive print method and a printer object.
This is a newer version of the helpers library. This script uses pinescripts v5 latest objects and methods.
Profiling: array of UDTs vs UDT of arraysUsing Stopwatch Library by PineCoders, I am trying to test which is faster, an array of user-defined type (UDT) objects vs an object with many child arrays.
The task is to store and manipulate array of objects having total 9 values: 4 floats, 4 strings and 1 int.
Option 1: create a UDT with 9 fields and store an array of such UDT objects.
Option 2: create a UDT with 9 arrays individually for each value.
The test task is of three stages:
Populate array(s) with some (timenow) values - in the options you can choose how many values to push into the array/arrays. Note that max size of array(s) is set independently, so you can push 1000 of elements into an array capped at 100 max size and as new elements will be pushed (added to the end) the old exceeding elements will be shifted (removed from the beginning)
Write - write to random elements of the array. Two options for writing to a UDT object: (1) assign to each field independently, (2) create a UDT object and use array.set() function.
Read - read from random elements of the array.
In the options you can how many times per bar to run each of the steps (same number for each step).
I tested by adding three indicators to the chart and choosing different options for each:
1. Array of UDT's where writing is done by creating a new UDT from the values and then using set(udt)
2. Array of UDT's where writing is done by assigning the value of each of the properties of the UDT individually (saving time on creating of a new object).
3. UDT of arrays.
As of 16 Arpil 2023 the UDT of arrays seems about 20-30% faster than the array of UDT's with setting each property without creating new UDT object.
Console๐ Console Library
๐ท Introduction
This script is an adaptation of the classic JavaScript console script. It provides a simple way to display data in a console-like table format for debugging purposes.
While there are many nice console/logger scripts out there, my personal goal was to achieve inline functionality and visual object (label, lines) logging .
๐ท How to Use
โผ 1. Import the Console library into your script:
import cryptolinx/Console/1
- or -
Instead of the library namespace, you can define a custom namespace as alias.
import cryptolinx/Console/1 as c
โผ 2. Create and init a new `` object.
The `init()` method is used to initialize the console object with default settings. It can be used to customize it.
// When using the `var` keyword in a declaration, the logs will act as ever-forwarding.
// Without `var`, the `console` variable will be redeclared every time `bar` is called.
// var console = Console.terminal.new(log_position=position.bottom_left, prefix = '> ', show_no = true)
- or -
If you has set up an alias before.
var console = c.terminal.new().init()
โผ 3. Logging
// inline โจ
array testArray = array.new(3, .0).log(console)
// basic
console.log(testArray)
// inline โจ
var testLabel = label.new(bar_index, close, 'Label Text').log(console)
// basic
console.log(testLabel)
// It is also possible to use `().` for literals โจ.
int a = 100
testCalc = (5 * 100).log(console) + a.log(console) // SUM: 600
console.
.empty()
.log('SUM' + WS + testCalc.tostring())
โผ 4. Visibility
Finally, we need to call the `show()` method to display the logged messages in the console.
console.show(true) // True by default. Simply turn it on or off
HTF Bars Discrepancy Detector (for debugging)Illustrate discrepancies between two symbols of the same higher timeframe.
Sometimes:
- HTF data can come for one symbol but not for another
- or come with gaps (e.g. after HTF bar 3 in the next chart TF's candle we have HTF bar 5 for one or both symbols)
ANTEYA ProfilingThis script allows to compare which code is more efficient by running it inside a loop for a certain time or a certain number of iterations.
Just paste your pieces of code as Option 1 and Option 2 inside the loop (see comments in the script).
Signal ViewerThe "Signal Viewer" script is a debugging tool that can be used for the signal of a Signal Indicator script like the "Two MA Signal Indicator" or the "Template Signal Indicator". This script will visualize the signal based on the convention that was defined in the settings. Also, alerts will be produced based on this convention. It's useful to be used before you connect the signal indicator script to a template strategy like the "Template Trailing Strategy" script. You can cross-validate the correctness of the signal that the indicators emit and make sure it is aligned with the expected behavior after the decomposition of the signal using the convention described in the settings. Please make sure that the connection in the "Signal Viewer" script matches the convention used by the template strategy script.

Debug tool - tableWhen having a script with lot's of values, it can be difficult to seek the values you need to debug
For example, here, multiple values aren't visible anymore (right side chart)
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
This script show a way where you can show the values in a table on 1 particular bar, with 2 options:
1)
'middle' -> here the script uses chart.left_visible_bar_time and chart.right_visible_bar_time to calculate the middle
the values of that bar (in orange box) is shown, you can check the value by putting your mouse cursor on that bar:
Just zooming in/out, or scrolling through history will automatically show you the middle and the values of that bar.
Using the arrows on your keyboard will allow you to go 1 bar further/back each time.
(Give it some time to load though, also, sometimes you need to click anywhere on the chart before arrows start working)
2)
'time' -> settings -> Date -> the orange bar will be placed on the chosen bar, the values will be placed in the table as well.
โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
If the table interfere with the candles, you can alterย the position without changing the placement of the orange bar -> settings -> position table
This script holds lots of values, just to show the difference between values placed on the chart, and values, placed in the table.
To make more clear how the script works, an 'example' (v_rsi1 / rsi1) is highlighted in the code itself
Cheers!

Simple debug functionSimple method I used to debug problem in my script.
For loop generates 5 numbers from the given depth. At present, depth is 9
Rules for generating the combinations are as follows:
First number is always 1
Two even numbers should not be adjacent to each other and two odd numbers should not be adjacent to each other
Numbers should be ordered in incremental order.
Print all possible combinations
While the logic above is just a random one. Debug method can be reused for any program.
Logging in Pine ScriptI'm building quite a lot of pretty complicated indicators/strategies in Pine Script. Quite often they don't work from the 1 try so I have to debug them heavily.
In Pine Script there are no fancy debuggers so you have to be creative. You can plot values on your screens, check them in the data window, etc.
If you want to display some textual information, you can plot some info as labels on the screen.
It's not the most convenient way, so with the appearance of tables in Pine Script, I decided to implement a custom logger that will allow me to track some useful information about my indicator over time.
Tables work much better for this kind of thing than labels. They're attached to your screen, you can nicely scale them and you can style them much better.
The idea behind it is very simple. I used few arrays to store the message, bar number, timestamp, and type of the message (you can color messages depend on the type for example).
There is a function log_msg that just append new messages to these arrays.
In the end, for the last bar, I create the table and display the last X messages in it.
In parameters, you can show/hide the entire journal, change the number of messages displayed and choose an offset. With offset, you can basically scroll through the history of messages.
Currently, I implemented 3 types of messages, and I color messages according to these types:
Message - gray
Warning - yellow
Error - red
Of course, it's a pretty simple example, you can create a much fancier way of styling your logs.
What do you think about it? Is it useful for you? What do you use to debug code in Pine Script?

Please remember that past performance may not be indicative of future results.
Due to various factors, including changing market conditions, the strategy may no longer perform as good as in historical backtesting.
This post and the script donโt provide any financial advice.
Combination Parabolic MA/IIR/ALMA Strategy, with other goodiesOkay, so this is a lot. It started mostly with me combining indicators and looking for ideal entry criteria.
It is also a collection of conditions, whether used or unused, for my current chosen "best" strategy. It is currently set how I like it, but it has changed with time, and will continue to do so. Within, there are variables that are unused, but offer some insight into the overall odds of a trade. They were, in fact, once used but fell out of favor. And all details for this strategy are within the comment header of the script.
As this evolves, I most certainly wont keep any future findings and hope for profit from my peers (yinz). Also, I'd like to give a sincere thanks to the people of TV for what I learned in a few month's time and their flexible membership plans. Basically, I'm just a mad scientist, but this monster's a masterpiece and folks here before me made many indirect contributions to it.

Okay guys, lastly and most importantly,
Each smack of the like button is a vote of your confidence in me, to my beautiful landladies, Celeste and Adele, that my rent will be caught up and that it won't always be a problem. Which, in my mind, makes me a graph. And they've got strong hands and don't sell the low. I more than respect that. Seriously. And I'm very grateful for their willingness to work with me, but the thing is that I didn't ask first; life just happens. But few are tolerant of others. And quite importantly, I truly believe that I will be successful one day, and that "thumbs-up" button is your vote of confidence. If you're not sure, then don't hit it yet. Maybe my scripts will boost your confidence in me :)

PS: And you know what? I'ma give a shout-out to Philakone for teaching me everything that I know about Elliot Wave . Absolutely. Two years ago, I would keep telling myself that one day I will put something in his gratuity wallet or pursue the paid courses. And, I still plan on it, because I'm grateful. And so also, to everybody else, I'm recommending him to learn from. because as a trader who might not know everything for free, you can certainly fill in the gaps with his altruistic offerings. And I'm betting that you will then feel more than inclined to buy the Udemy course.
"If wave 2 retraces a lot; number 4 will not". Repetition. Philakone didn't fix my memory but he sure did find a workaround, haha
Okay, everyone, Thanks!
