Release notes

This page contains release notes of notable changes in Pine Script™.

June 2022

The behavior of the argument used with the qty_percent parameter of strategy.exit() has changed. Previously, the percentages used on successive exit orders of the same position were calculated from the remaining position at any given time. Instead, the percentages now always apply to the initial position size. When executing the following strategy, for example:

//@version=5
strategy("strategy.exit() example", overlay = true)
strategy.entry("Long", strategy.long, qty = 100)
strategy.exit("Exit Long1", "Long", trail_points = 50, trail_offset = 0, qty_percent = 20)
strategy.exit("Exit Long2", "Long", trail_points = 100, trail_offset = 0, qty_percent = 20)

20% of the initial position will be closed on each strategy.exit() call. Before, the first call would exit 20% of the initial position, and the second would exit 20% of the remaining 80% of the position, so only 16% of the initial position.

Two new parameters for the built-in ta.vwap() function were added:

  • anchor - Specifies the condition that triggers the reset of VWAP calculations. When true, calculations reset; when false, calculations proceed using the values accumulated since the previous reset.
  • stdev_mult - If specified, the ta.vwap() calculates the standard deviation bands based on the main VWAP series and returns a [vwap, upper_band, lower_band] tuple.

New overloaded versions of the strategy.close() and strategy.close_all() functions with the immediately parameter. When immediately is set to true, the closing order will be executed on the tick where it has been placed, ignoring the strategy parameters that restrict the order execution to the open of the next bar.

New built-in functions were added:

  • timeframe.change() - Returns true on the first bar of a new timeframe, false otherwise.
  • ta.pivot_point_levels() - Returns a float array with numerical values representing 11 pivot point levels: [P, R1, S1, R2, S2, R3, S3, R4, S4, R5, S5]. Levels absent from the specified type return na values.

New built-in variables were added:

May 2022

Matrix support has been added to the request.security() function.

The historical states of arrays and matrices can now be referenced with the [] operator. In the example below, we reference the historic state of a matrix 10 bars ago:

//@version=5
indicator("matrix.new<float> example")
m = matrix.new<float>(1, 1, close)
float x = na
if bar_index > 10
    x := matrix.get(m[10], 0, 0)
plot(x)
plot(close)

The ta.change() function now can take values of int and bool types as its source parameter and return the difference in the respective type.

New built-in variables were added:

  • chart.bg_color - Returns the color of the chart’s background from the "Chart settings/Appearance/Background" field.
  • chart.fg_color - Returns a color providing optimal contrast with chart.bg_color.
  • chart.is_standard - Returns true if the chart type is bars, candles, hollow candles, line, area or baseline, false otherwise.
  • currency.USDT - A constant for the Tether currency code.

New functions were added:

  • syminfo.prefix() - returns the exchange prefix of the symbol passed to it, e.g. “NASDAQ” for “NASDAQ:AAPL”.
  • syminfo.ticker() - returns the ticker of the symbol passed to it without the exchange prefix, e.g. “AAPL” for “NASDAQ:AAPL”.
  • request.security_lower_tf() - requests data from a lower timeframe than the chart’s.

Added use_bar_magnifier parameter for the strategy() function. When true, the Broker Emulator uses lower timeframe data during history backtesting to achieve more realistic results.

Fixed behaviour of strategy.exit() function when stop loss triggered at prices outside the bars price range.

Added new comment and alert message parameters for the strategy.exit() function:

  • comment_profit - additional notes on the order if the exit was triggered by crossing profit or limit specifically.
  • comment_loss - additional notes on the order if the exit was triggered by crossing stop or loss specifically.
  • comment_trailing - additional notes on the order if the exit was triggered by crossing trail_offset specifically.
  • alert_profit - text that will replace the '{{strategy.order.alert_message}}' placeholder if the exit was triggered by crossing profit or limit specifically.
  • alert_loss - text that will replace the '{{strategy.order.alert_message}}' placeholder if the exit was triggered by crossing stop or loss specifically.
  • alert_trailing - text that will replace the '{{strategy.order.alert_message}}' placeholder if the exit was triggered by crossing trail_offset specifically.

Table merging and cell tooltips

  • It is now possible to merge several cells in a table. A merged cell doesn’t have to be a header: you can merge cells in any direction, as long as the resulting cell doesn’t affect any already merged cells and doesn’t go outside of the table’s bounds. Cells can be merged with the new table.merge_cells() function.
  • Tables now support tooltips, floating labels that appear when you hover over a table’s cell. To add a tooltip, pass a string to the tooltip argument of the table.cell() function or use the new table.cell_set_tooltip() function.

February 2022

Added templates and the ability to create arrays via templates. Instead of using one of the array.new_*() functions, a template function array.new<type> can be used. In the example below, we use this functionality to create an array filled with float values:

//@version=5
indicator("array.new<float> example")
length = 5
var a = array.new<float>(length, close)
if array.size(a) == length
        array.remove(a, 0)
        array.push(a, close)
plot(array.sum(a) / length, "SMA")

New functions were added:

January 2022

Added new functions to clone drawings:

December 2021

Linefills

The space between lines drawn in Pine Script™ can now be filled! We’ve added a new linefill drawing type, along with a number of functions dedicated to manipulating it. Linefills are created by passing two lines and a color to the linefill.new() function, and their behavior is based on the lines they’re tied to: they extend in the same direction as the lines, move when their lines move, and are deleted when one of the two lines is deleted.

New linefill-related functions:

New functions for string manipulation

Added a number of new functions that provide more ways to process strings, and introduce regular expressions to Pine Script™:

Textboxes

Box drawings now supports text. The box.new() function has five new parameters for text manipulation: text, text_size, text_color, text_valign, and text_halign. Additionally, five new functions to set the text properties of existing boxes were added:

New built-in variables

Added new built-in variables that return the bar_index and time values of the last bar in the dataset. Their values are known at the beginning of the script’s calculation:

New built-in source variable:

  • hlcc4 - A shortcut for (high + low + close + close)/4. It averages the high and low values with the double-weighted close.

November 2021

for…in

Added a new for…in operator to iterate over all elements of an array:

//@version=5
indicator("My Script")
int[] a1 = array.from(1, 3, 6, 3, 8, 0, -9, 5)

highest(array) =>
    var int highestNum = na
    for item in array
        if na(highestNum) or item > highestNum
            highestNum := item
    highestNum

plot(highest(a1))

Function overloads

Added function overloads. Several functions in a script can now share the same name, as long one of the following conditions is true:

  • Each overload has a different number of parameters:

    //@version=5
    indicator("Function overload")
    
    // Two parameters
    mult(x1, x2) =>
        x1 * x2
    
    // Three parameters
    mult(x1, x2, x3) =>
        x1 * x2 * x3
    
    plot(mult(7, 4))
    plot(mult(7, 4, 2))
    
  • When overloads have the same number of parameters, all parameters in each overload must be explicitly typified, and their type combinations must be unique:

    //@version=5
    indicator("Function overload")
    
    // Accepts both 'int' and 'float' values - any 'int' can be automatically cast to 'float'
    mult(float x1, float x2) =>
        x1 * x2
    
    // Returns a 'bool' value instead of a number
    mult(bool x1, bool x2) =>
        x1 and x2 ? true : false
    
    mult(string x1, string x2) =>
        str.tonumber(x1) * str.tonumber(x2)
    
    // Has three parameters, so explicit types are not required
    mult(x1, x2, x3) =>
        x1 * x2 * x3
    
    plot(mult(7, 4))
    plot(mult(7.5, 4.2))
    plot(mult(true, false) ? 1 : 0)
    plot(mult("5", "6"))
    plot(mult(7, 4, 2))
    

Currency conversion

Added a new currency argument to most request.*() functions. If specified, price values returned by the function will be converted from the source currency to the target currency. The following functions are affected:

October 2021

Pine Script™ v5 is here! This is a list of the new features added to the language, and a few of the changes made. See the Migration guide to Pine Script™ v5 for a complete list of the changes in v5.

New features

Libraries are a new type of publication. They allow you to create custom functions for reuse in other scripts. See this manual’s page on Libraries.

Pine Script™ now supports switch structures! They provide a more convenient and readable alternative to long ternary operators and if statements.

while loops are here! They allow you to create a loop that will only stop when its controlling condition is false, or a break command is used in the loop.

New built-in array variables are maintained by the Pine Script™ runtime to hold the IDs of all the active objects of the same type drawn by your script. They are label.all, line.all, box.all and table.all.

The runtime.error() function makes it possible to halt the execution of a script and display a runtime error with a custom message. You can use any condition in your script to trigger the call.

Parameter definitions in user-defined functions can now include a default value: a function defined as f(x = 1) => x will return 1 when called as f(), i.e., without providing an argument for its x parameter.

New variables and functions provide better script visibility on strategy information:

A new earnings.standardized constant for the request.earnings() function allows requesting standardized earnings data.

A v4 to v5 converter is now included in the Pine Script™ Editor. See the Migration guide to Pine Script™ v5 for more information on converting your scripts to v5.

The Reference Manual now includes the systematic mention of the form and type (e.g., “simple int”) required for each function parameter.

The User Manual was reorganized and new content was added.

Changes

Many built-in variables, functions and function arguments were renamed or moved to new namespaces in v5. The venerable study(), for example, is now indicator(), and security() is now request.security(). New namespaces now group related functions and variables together. This consolidation implements a more rational nomenclature and provides an orderly space to accommodate the many additions planned for Pine Script™.

See the Migration guide to Pine Script™ v5 for a complete list of the changes made in v5.

September 2021

New parameter has been added for the dividends(), earnings(), financial(), quandl(), security(), and splits() functions:

  • ignore_invalid_symbol - determines the behavior of the function if the specified symbol is not found: if false, the script will halt and return a runtime error; if true, the function will return na and execution will continue.

July 2021

tostring now accepts “bool” and “string” types.

New argument for time and time_close functions was added:

  • timezone - timezone of the session argument, can only be used when a session is specified. Can be written out in GMT notation (e.g. “GMT-5”) or as an IANA time zone database name (e.g. “America/New_York”).

It is now possible to place a drawing object in the future with xloc = xloc.bar_index.

New argument for study and strategy functions was added:

  • explicit_plot_zorder - specifies the order in which the indicator’s plots, fills, and hlines are rendered. If true, the plots will be drawn based on the order in which they appear in the indicator’s code, each newer plot being drawn above the previous ones.

June 2021

New variable was added:

  • barstate.islastconfirmedhistory - returns true if script is executing on the dataset’s last bar when market is closed, or script is executing on the bar immediately preceding the real-time bar, if market is open. Returns false otherwise.

New function was added:

  • round_to_mintick(x) - returns the value rounded to the symbol’s mintick, i.e. the nearest value that can be divided by syminfo.mintick, without the remainder, with ties rounding up.

Expanded tostring() functionality. The function now accepts three new formatting arguments:

  • format.mintick to format to tick precision.
  • format.volume to abbreviate large values.
  • format.percent to format percentages.

May 2021

Improved backtesting functionality by adding the Leverage mechanism.

Added support for table drawings and functions for working with them. Tables are unique objects that are not anchored to specific bars; they float in a script’s space, independently of the chart bars being viewed or the zoom factor used. For more information, see the Tables User Manual page.

New functions were added:

  • color.rgb(red, green, blue, transp) - creates a new color with transparency using the RGB color model.
  • color.from_gradient(value, bottom_value, top_value, bottom_color, top_color) - returns color calculated from the linear gradient between bottom_color to top_color.
  • color.r(color), color.g(color), color.b(color), color.t(color) - retrieves the value of one of the color components.
  • array.from() - takes a variable number of arguments with one of the types: int, float, bool, string, label, line, color, box, table and returns an array of the corresponding type.

A new box drawing has been added to Pine Script™, making it possible to draw rectangles on charts using the Pine Script™ syntax. For more details see the Pine Script™ reference and the Lines and boxes User Manual page.

The color.new function can now accept series and input arguments, in which case, the colors will be calculated at runtime. For more information about this, see our Colors User Manual page.

Added a detailed description of all the fields in the Strategy Tester Report

February 2020

  • New Pine Script™ indicator VWAP Anchored was added. Now you can specify the time period: Session, Month, Week, Year.

  • Fixed a problem with calculating percentrank function. Now it can return a zero value, which did not happen before due to an incorrect calculation.

  • The default transparency parameter for the plot(), plotshape(), and plotchar() functions is now 0%.

  • For the functions plot(), plotshape(), plotchar(), plotbar(), plotcandle(), plotarrow(), you can set the display parameter, which controls the display of the plot. The following values can be assigned to it:

    • display.none - the plot is not displayed
    • display.all - the plot is displayed (Default)
  • The textalign argument was added to the label.new function along with the label.set_textalign function. Using those, you can control the alignment of the label’s text:

    //@version=4
    study("My Script", overlay = true)
    var l = label.new(bar_index, high, text="Right\n aligned\n text", textalign=text.align_right)
    label.set_xy(l, bar_index, high)

New parameters were added for strategy.close():

  • qty - the number of contracts/shares/lots/units to exit a trade with
  • qty_percent - defines the percentage of entered contracts/shares/lots/units to exit a trade with
  • comment - addtional notes on the order

New parameter was added for strategy.close_all:

  • comment - additional notes on the order

2019

December 2019

  • Warning messages were added.

    For example, if you don’t specify exit parameters for strategy.exit - profit, limit, loss, stop or one of the following pairs: trail_offset and trail_price / trail_points - you will see a warning message in the console in the Pine Script™ editor.

  • Increased the maximum number of arguments in max, min, avg functions. Now you can use up to ten arguments in these functions.

October 2019

  • plotchar() function now supports most of the Unicode symbols:

    //@version=4
    study("My Script", overlay=true)
    plotchar(open > close, char="🐻")
    
    _images/ReleaseNotes-Bears_in_plotchar.png
  • New bordercolor argument of the plotcandle() function allows you to change the color of candles’ borders:

    //@version=4
    study("My Script")
    plotcandle(open, high, low, close, title='Title', color = open < close ? color.green : color.red, wickcolor=color.black, bordercolor=color.orange)
    
  • New variables added:

    • syminfo.description - returns a description of the current symbol
    • syminfo.currency - returns the currency code of the current symbol (EUR, USD, etc.)
    • syminfo.type - returns the type of the current symbol (stock, futures, index, etc.)

September 2019

New parameters to the strategy function were added:

  • process_orders_on_close allows the broker emulator to try to execute orders after calculating the strategy at the bar’s close
  • close_entries_rule allows to define the sequence used for closing positions

Some fixes were made:

  • fill() function now works correctly with na as the color parameter value
  • sign() function now calculates correctly for literals and constants

str.replace_all(source, target, replacement) function was added. It replaces each occurrence of a target string in the source string with a replacement string

July-August 2019

New variables added:

  • timeframe.isseconds returns true when current resolution is in seconds
  • timeframe.isminutes returns true when current resolution is in minutes
  • time_close returns the current bar’s close time

The behavior of some functions, variables and operators has changed:

  • The time variable returns the correct open time of the bar for more special cases than before

  • An optional seconds parameter of the timestamp() function allows you to set the time to within seconds

  • security() function:

    • Added the possibility of requesting resolutions in seconds:

      1, 5, 15, 30 seconds (chart resolution should be less than or equal to the requested resolution)

    • Reduced the maximum value that can be requested in some of the other resolutions:

      from 1 to 1440 minutes

      from 1 to 365 days

      from 1 to 52 weeks

      from 1 to 12 months

  • Changes to the evaluation of ternary operator branches:

    In Pine Script™ v3, during the execution of a ternary operator, both its branches are calculated, so when this script is added to the chart, a long position is opened, even if the long() function is not called:

    //@version=3
    strategy(title = "My Strategy")
    long() =>
        strategy.entry("long", true, 1, when = open > high[1])
        1
    c = 0
    c := true ? 1 : long()
    plot(c)
    

    Pine Script™ v4 contains built-in functions with side effects ( line.new and label.new ). If calls to these functions are present in both branches of a ternary operator, both function calls would be executed following v3 conventions. Thus, in Pine Script™ v4, only the branch corresponding to the evaluated condition is calculated. While this provides a viable solution in some cases, it will modify the behavior of scripts which depended on the fact that both branches of a ternary were evaluated. The solution is to pre-evaluate expressions prior to the ternary operator. The conversion utility takes this requirement into account when converting scripts from v3 to v4, so that script behavior will be identical in v3 and v4.

    • An implicit conversion of boolean values to numeric values was replaced with an implicit conversion of numeric values (integer and float) to boolean values.
    • Self-referenced and forward-referenced variables were removed. Any PineScript code that used those language constructions can be equivalently rewritten using mutable variables.

February 2017

  • Several improvements to the strategy tester and the strategy report:
    • New Buy & Hold equity graph – a new graph that lets you compare performance of your strategy versus a “buy and hold”, i.e if you just bought a security and held onto it without trading.
    • Added percentage values to the absolute currency values.
    • Added Buy & Hold Return to display the final value of Buy & Hold Equity based on last price.
    • Added Sharpe Ratio – it shows the relative effectiveness of the investment portfolio (security), a measure that indicates the average return minus the risk-free return divided by the standard deviation of return on an investment.
    • Slippage lets you simulate a situation when orders are filled at a worse price than expected. It can be set through the Properties dialog or through the slippage argument in the strategy() function.
    • Commission allows yot to add commission for placed orders in percent of order value, fixed price or per contract. The amount of commission paid is shown in the Commission Paid field. The commission size and its type can be set through the Properties dialog or through the commission_type and commission_value arguments in the strategy() function.

Strategies allow you to perform backtesting (emulation of strategy trading on historical data) and forward testing (emulation of strategy trading on real-time data) according to your algorithms. Detailed information about the strategy’s calculations and the order fills can be seen in the newly added Strategy Tester tab.

July 2015

  • A new editable parameter allows hiding the plot from the Style menu in the indicator settings so that it is not possible to edit its style. The parameter has been added to all the following functions: all plot-type functions, barcolor(), bgcolor(), hline(), and fill().

June 2015
