# Finance::Quote - phpMan

## NAME
    [Finance::Quote] - Get stock and mutual fund quotes from various exchanges

## SYNOPSIS
       use [Finance::Quote];

       $q = [Finance::Quote]->new;
       %quotes  = $q->fetch("nasdaq", @stocks);

## DESCRIPTION
    This module gets stock quotes from various internet sources all over the
    world. Quotes are obtained by constructing a quoter object and using the
    fetch method to gather data, which is returned as a two-dimensional hash
    (or a reference to such a hash, if called in a scalar context). For
    example:

        $q = [Finance::Quote]->new;
        %info = $q->fetch("australia", "CML");
        print "The price of CML is ".$info{"CML", "price"};

    The first part of the hash (eg, "CML") is referred to as the stock. The
    second part (in this case, "price") is referred to as the label.

  LABELS
    When information about a stock is returned, the following standard
    labels may be used. Some custom-written modules may use labels not
    mentioned here. If you wish to be certain that you obtain a certain set
    of labels for a given stock, you can specify that using
    require_labels().

## PUBLIC CLASS METHODS
    [Finance::Quote] implements public class methods for constructing a quoter
    object, getting or setting default class values, and for listing
    available methods.

  new
        my $q = [Finance::Quote]->new()
        my $q = [Finance::Quote]->new('-defaults')
        my $q = [Finance::Quote]->new('AEX', 'Fool')
        my $q = [Finance::Quote]->new(timeout => 30)
        my $q = [Finance::Quote]->new('YahooJSON', fetch_currency => 'EUR')
        my $q = [Finance::Quote]->new('alphavantage' => {API_KEY => '...'})
        my $q = [Finance::Quote]->new('IEXCloud', 'iexcloud' => {API_KEY => '...'});
        my $q = [Finance::Quote]->new(currency_rates => {order => ['ECB', 'Fixer'], 'fixer' => {API_KEY => '...'}});

    [Finance::Quote] modules access a wide range of sources to provide quotes.
    A module provides one or more methods to fetch quotes. One method is
    usually the name of the module in lower case. Other methods, if
    provided, are descriptive names, such as 'canada', 'nasdaq', or 'nyse'.

    A [Finance::Quote] object uses one or more methods to fetch quotes for
    securities.

    "new" constructs a [Finance::Quote] object and enables the caller to load
    only specific modules, set parameters that control the behavior of the
    fetch method, and pass method specific parameters.

    "timeout =" T> sets the web request timeout to "T" seconds
    "failover =" B> where "B" is a boolean value indicating if failover in
    fetch is permitted
    "fetch_currency =" C> sets the desired currency code to "C" for fetch
    results
    "currency_rates =" H> configures the order currency rate modules are
    consulted for exchange rates and currency rate module options
    "required_labels =" A> sets the required labels for fetch results to
    array "A"
    "<ModuleName"> as a string is the name of a specific
    [Finance::Quote::Module] to load
    "<methodname" => H> passes hash "H" to methodname during fetch to
    configure the method

    With no arguments, "new" creates a [Finance::Quote] object with the
    default methods. If the environment variable FQ_LOAD_QUOTELET is set,
    then the contents of FQ_LOAD_QUOTELET (split on whitespace) will be used
    as the argument list. This allows users to load their own custom modules
    without having to change existing code. If any method names are passed
    to "new" or the flag '-defaults' is included in the argument list, then
    FQ_LOAD_QUOTELET is ignored.

    When new() is passed one or more class name arguments, an object is
    created with only the specified modules loaded. If the first argument is
    '-defaults', then the default modules will be loaded first, followed by
    any other specified modules. Note that the FQ_LOAD_QUOTELET environment
    variable must begin with '-defaults' if you wish the default modules to
    be loaded.

    Method names correspond to the Perl module in the [Finance::Quote] module
    space. For example, "[Finance::Quote]-"new('ASX')> will load the module
    [Finance::Quote::ASX], which provides the method "asx".

    Some methods require API keys or have unique options. Passing 'method =>
    HASH' to new() enables the caller to provide a configuration HASH to the
    corresponding method.

    The key 'currency_rates' configures the [Finanace::Quote] currency rate
    conversion. By default, to maintain backward compatibility,
    [Finance::Quote::CurrencyRates::AlphaVantage] is used for currency
    conversion. This end point requires an API key, which can either be set
    in the environment or included in the configuration hash. To specify a
    different primary currency conversion method or configure fallback
    methods, include the 'order' key, which points to an array of
    [Finance::Quote::CurrencyRates] module names. See the documentation for
    the individual [Finance::Quote::CurrencyRates] to learn more.

  get_default_currency_fields
        my @fields = [Finance::Quote::get_default_currency_fields]();

    "get_default_currency_fields" returns the standard list of fields in a
    quote that are automatically converted during currency conversion.
    Individual modules may override this list.

  get_default_timeout
        my $value = [Finance::Quote::get_default_timeout]();

    "get_default_timeout" returns the current [Finance::Quote] default timeout
    in seconds for web requests. [Finance::Quote] does not specify a default
    timeout, deferring to the underlying user agent for web requests. So
    this function will return undef unless "set_default_timeout" was
    previously called.

  set_default_timeout
        [Finance::Quote]::[set_default_timeout(45)];

    "set_default_timeout" sets the [Finance::Quote] default timeout to a new
    value.

  get_methods
        my @methods = [Finance::Quote::get_methods]();

    "get_methods" returns the list of methods that can be passed to "new"
    when creating a quoter object and as the first argument to "fetch".

## PUBLIC OBJECT METHODS
  B_to_billions
        my $value = $q->B_to_billions("20B");

    "B_to_billions" is a utility function that expands a numeric string with
    a "B" suffix to the corresponding multiple of 1000000000.

  decimal_shiftup
        my $value = $q->decimal_shiftup("123.45", 1);  # returns 1234.5
        my $value = $q->decimal_shiftup("0.25", 1);    # returns 2.5

    "decimal_shiftup" moves a the decimal point in a numeric string the
    specified number of places to the right.

  fetch
        my %stocks  = $q->fetch("alphavantage", "IBM", "MSFT", "LNUX");
        my $hashref = $q->fetch("nasdaq", "IBM", "MSFT", "LNUX");

    "fetch" takes a method as its first argument and the remaining arguments
    are treated as securities. If the quoter $q was constructed with a
    specific method or methods, then only those methods are available.

    When called in an array context, a hash is returned. In a scalar
    context, a reference to a hash will be returned. The keys for the
    returned hash are "{SECURITY,LABEL}". For the above example call,
    $stocks{"IBM","high"} is the high value for IBM.

    $q->get_methods() returns the list of valid methods for quoter object
    $q. Some methods specify a specific [Finance::Quote] module, such as
    'alphavantage'. Other methods are available from multiple [Finance::Quote]
    modules, such as 'nasdaq'. The quoter failover over option determines if
    multiple modules are consulted for methods such as 'nasdaq' that more
    than one implementation.

  get_failover
        my $failover = $q->get_failover();

    Failover is when the "fetch" method attempts to retrieve quote
    information for a security from alternate sources when the requested
    method fails. "get_failover" returns a boolean value indicating if the
    quoter object will use failover or not.

  set_failover
        $q->set_failover(False);

    "set_failover" sets the failover flag on the quoter object.

  get_fetch_currency
        my $currency = $q->get_fetch_currency();

    "get_fetch_currency" returns either the desired currency code for the
    quoter object or undef if no target currency was set during construction
    or with the "set_fetch_currency" function.

  set_fetch_currency
        $q->set_fetch_currency("FRF");  # Get results in French Francs.

    "set_fetch_currency" method is used to request that all information be
    returned in the specified currency. Note that this increases the chance
    stock-lookup failure, as remote requests must be made to fetch both the
    stock information and the currency rates. In order to improve
    reliability and speed performance, currency conversion rates are cached
    and are assumed not to change for the duration of the [Finance::Quote]
    object.

    See the introduction to this page for information on how to configure
    the source of currency conversion rates.

  get_required_labels
        my @labels = $q->get_required_labels();

    "get_required_labels" returns the list of labels that must be populated
    for a security quote to be considered valid and returned by "fetch".

  set_required_labels
        my $labels = ['close', 'isodate', 'last'];
        $q->set_required_labels($labels);

    "set_required_labels" updates the list of required labels for the quoter
    object.

  get_timeout
        my $timeout = $q->get_timeout();

    "get_timeout" returns the timeout in seconds the quoter object is using
    for web requests.

  set_timeout
        $q->[set_timeout(45)];

    "set_timeout" updated the timeout in seconds for the quoter object.

  store_date
        $quoter->store_date(\%info, $stocks, {eurodate => '06/11/2020'});

    "store_date" is used by modules to consistent store date information
    about securities. Given the various pieces of a date, this function
    figures out how to construct a ISO date (yyyy-mm-dd) and US date
    (mm/dd/yyyy) and stores those values in %info for security $stock.

  get_user_agent
        my $ua = $q->get_user_agent();

    "get_user_agent" returns the [LWP::UserAgent] the quoter object is using
    for web requests.

  isoTime
        $q->isoTime("11:39PM");    # returns "23:39"
        $q->isoTime("9:10 AM");    # returns "09:10"

    "isoTime" returns an ISO formatted time.

## PUBLIC CLASS OR OBJECT METHODS
    The following methods are available as class methods, but can also be
    called from [Finance::Quote] objects.

  scale_field
        my $value = [Finance::Quote]->scale_field('1023', '0.01')

    "scale_field" is a utility function that scales the first argument by
    the second argument. In the above example, "value" is '10.23'.

  currency
        my $value = $q->currency('15.95 USD', 'AUD');
        my $value = [Finance::Quote]->currency('23.45 EUR', 'RUB');

    "currency" converts a value with a currency code suffix to another
    currency using the current exchange rate as determined by the
    [Finance::Quote::CurrencyRates] method or methods configured for the
    quoter $q. When called as a class method, only
    [Finance::Quote::AlphaVantage] is used, which requires an API key. See the
    introduction for information on configuring currency rate conversions
    and see [Finance::Quote::CurrencyRates::AlphaVantage] for information
    about the API key.

  currency_lookup
        my $currency = $quoter->currency_lookup();
        my $currency = $quoter->currency_lookup( name => "Caribbean");
        my $currency = $quoter->currency_loopup( country => qw/denmark/i );
        my $currency = $q->currency_lookup(country => qr/united states/i, number => 840);

    "currency_lookup" takes zero or more constraints and filters the list of
    currencies known to [Finance::Quote]. It returns a hash reference where
    the keys are ISO currency codes and the values are hash references
    containing metadata about the currency.

    A constraint is a key name and either a scalar or regular expression. A
    currency satisfies the constraint if its metadata hash contains the
    constraint key and the value of that metadata field matches the regular
    expression or contains the constraint value as a substring. If the
    metadata field is an array, then it satisfies the constraint if any
    value in the array satisfies the constraint.

  parse_csv
        my @list = [Finance::Quote::parse_csv]($string);

    "parse_csv" is a utility function for splitting a comma separated value
    string into a list of terms, treating double-quoted strings that contain
    commas as a single value.

  parse_csv_semicolon
        my @list = [Finance::Quote::parse_csv_semicolon]($string);

    "parse_csv" is a utility function for splitting a semicolon separated
    value string into a list of terms, treating double-quoted strings that
    contain semicolons as a single value.

## LEGACY METHODS
  default_currency_fields
    Replaced with get_default_currency_fields().

  sources
    Replaced with get_methods().

  failover
    Replaced with get_failover() and set_failover().

  require_labels
    Replaced with get_required_labels() and set_required_labels().

  user_agent
    Replaced with get_user_agent().

  set_currency
    Replaced with get_fetch_currency() and set_fetch_currency().

## ENVIRONMENT
    [Finance::Quote] respects all environment that your installed version of
    [LWP::UserAgent] respects. Most importantly, it respects the http_proxy
    environment variable.

## BUGS
    The caller cannot control the fetch failover order.

    The two-dimensional hash is a somewhat unwieldly method of passing
    around information when compared to references
