Release notes

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

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.

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 our User Manual page on tables.

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, making it possible to draw rectangles on charts using the Pine syntax. For more details see the Pine Script reference and the User Manual page on drawings .

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 User Manual page on colors.

April 2021

New math constants were added:

  • math.pi - is a named constant for Archimedes’ constant. It is equal to 3.1415926535897932.
  • math.phi - is a named constant for the golden ratio. It is equal to 1.6180339887498948.
  • math.rphi - is a named constant for the golden ratio conjugate. It is equal to 0.6180339887498948.

New math functions were added:

  • round(x, precision) - returns the value of x rounded to the nearest integer, with ties rounding up. If the precision parameter is used, returns a float value rounded to that number of decimal places.
  • median(source, length) - returns the median of the series.
  • mode(source, length) - returns the mode of the series. If there are several values with the same frequency, it returns the smallest value.
  • range(source, length) - returns the difference between the min and max values in a series.
  • todegrees(radians) - returns an approximately equivalent angle in degrees from an angle measured in radians.
  • toradians(degrees) - returns an approximately equivalent angle in radians from an angle measured in degrees.
  • random(min, max, seed) - returns a pseudo-random value. The function will generate a different sequence of values for each script execution. Using the same value for the optional seed argument will produce a repeatable sequence.

New functions were added:

  • session.ismarket - returns true if the current bar is a part of the regular trading hours (i.e. market hours), false otherwise.
  • session.ispremarket - returns true if the current bar is a part of the pre-market, false otherwise.
  • session.ispostmarket - returns true if the current bar is a part of the post-market, false otherwise.

  • 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 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 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 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.
