marketanalysis

A fast, efficient Python library for generating market holidays and trading days based on countries' security exchanges. It aims to make determining whether a specific date is a market holiday as fast and flexible as possible.

Example Usage

from datetime import date
from marketanalysis import marketholidays
from marketanalysis import markettradingdays

us_marketholidays = marketholidays.UnitedStates()
# or:
# us_marketholidays = marketholidays.US()
# or:
# us_marketholidays = marketholidays.CountryHoliday('US')
# or, for specific prov / states:
# us_marketholidays = marketholidays.CountryHoliday('US', prov=None, state='CA')

date(2015, 1, 1) in us_marketholidays  # True
date(2015, 1, 2) in us_marketholidays  # False

# The Holiday class will also recognize strings of any format
# and int/float representing a Unix timestamp
'2014-01-01' in us_marketholidays  # True
'1/1/2014' in us_marketholidays    # True
1388597445 in us_marketholidays    # True

us_marketholidays.get('2014-01-01')  # "New Year's Day"

us_marketholidays['2014-01-01': '2014-01-03']  # [date(2014, 1, 1)]

us_pr_marketholidays = marketholidays.UnitedStates()  # or marketholidays.US(...), or marketholidays.CountryHoliday('US', state='PR')

# some marketholidays are only present in parts of a country
'2018-01-06' in us_marketholidays     # False
'2018-01-06' in us_pr_marketholidays  # True

# Easily create custom Holiday objects with your own dates instead
# of using the pre-defined countries/states/provinces available
custom_marketholidays = marketholidays.MarketHolidayBase()
# Append custom holiday dates by passing:
# 1) a dict with date/name key/value pairs,
custom_marketholidays.append({"2015-01-01": "New Year's Day"})
# 2) a list of dates (in any format: date, datetime, string, integer),
custom_marketholidays.append(['2015-07-01', '07/04/2015'])
# 3) a single date item
custom_marketholidays.append(date(2015, 12, 25))

date(2015, 1, 1) in custom_marketholidays  # True
date(2015, 1, 2) in custom_marketholidays  # False
'12/25/2015' in custom_marketholidays      # True

# For more complex logic like 4th Monday of January, you can inherit the
# HolidayBase class and define your own _populate(year) method. See below
# documentation for examples.

API

class marketholidays.MarketHolidayBase(years=[], expand=True, observed=True, prov=None, state=None)

The base class used to create holiday country classes.

Parameters:

years

An iterable list of integers specifying the years that the Holiday object should pre-generate. This would generally only be used if setting expand to False. (Default: [])

expand

A boolean value which specifies whether or not to append marketholidays in new years to the marketholidays object. (Default: True)

observed

A boolean value which when set to True will include the observed day of a holiday that falls on a weekend, when appropriate. (Default: True)

prov

A string specifying a province that has unique statutory marketholidays. (Default: Canada='ON')

state

A string specifying a state that has unique statutory marketholidays. (Default: UnitedStates=None)

Methods:

get(key, default=None)

Returns a string containing the name of the holiday(s) in date key, which can be of date, datetime, string, unicode, bytes, integer or float type. If multiple marketholidays fall on the same date the names will be separated by commas

get(key, default=None)

Returns a string containing the name of the holiday(s) in date key, which can be of date, datetime, string, unicode, bytes, integer or float type. If multiple marketholidays fall on the same date the names will be separated by commas

get_list(key)

Same as get except returns a list of holiday names instead of a comma separated string

get_named(name)

Returns a list of marketholidays matching (even partially) the provided name (case insensitive check)

pop(key, default=None)

Same as get except the key is removed from the holiday object

pop_named(name)

Same as pop but takes the name of the holiday (or part of it) rather than the date

update/append

Accepts dictionary of {date: name} pairs, a list of dates, or even singular date/string/timestamp objects and adds them to the list of marketholidays

# Simplest example possible

>>> from datetime import date
>>> from marketanalysis import marketholidays
>>> date(2021, 4, 2) in marketholidays.US()
True
>> date(2021, 1, 2) in marketholidays.US()
False

# However, this is not efficient because it is initializing a new market holiday
# object and generating a list of all the holidays in 2021 during each comparison.

# It is more efficient to create the object only once

>>> us_marketholidays = marketholidays.US()
>>> date(2021, 4, 2) in us_marketholidays
True
>> date(2021, 1, 2) in us_marketholidays
False

# You can pick whichever you prefer of the following two.

>>> marketholidays.UnitedStates() == marketholidays.US()
True


# Let's print out the market holidays in 2021 specific to NYSE and NASDAQ
