NAME

Finance::MtGox - trade Bitcoin with the MtGox API

VERSION

Version 0.03

SYNOPSIS

use Finance::MtGox;
my $mtgox = Finance::MtGox->new({
  user     => 'username',
  password => 'secret',
});
# 'key' and 'secret' authentication works too

# unauthenticated API calls
my $depth = $mtgox->call('getDepth');

# authenticated API calls
my $funds = $mtgox->call_auth('getFunds');

# convenience methods built on the core API
my ( $btcs, $usds ) = $mtgox->balances;
my $rate = $mtgox->clearing_rate( 'asks', 200, 'BTC' );
$rate    = $mtgox->clearing_rate( 'bids',  42, 'USD' );

BASIC METHODS

new

Create a new Finance::MtGox object with your MtGox credentials provided in the user and password arguments.

You can also provide credentials with key and secret arguments. This allows access to MtGox's newer API which has more methods.

call($name)

Run the API call named $name. Returns a Perl data structure representing the JSON returned from MtGox.

call_auth( $name, $args )

Run the API call named $name with arguments provided by the hashref $args. Returns a Perl data structure representing the JSON returned from MtGox

CONVENIENCE METHODS

balances

Returns a list with current BTC and USD account balances, respectively.

clearing_rate( $side, $amount, $currency )

Traverse the current "asks" or "bids" ($side) on the order book until the given amount of currency has been consumed. Returns the resulting market clearing rate. This method is useful when trying to determine how much you'd have to pay to purchase $40 worth of BTC:

my $rate = $mtgox->clearing_rate( 'asks', 40, 'USD' );

Similar code for determining the rate to sell 40 BTC:

my $rate = $mtgox->clearing_rate( 'bids', 40, 'BTC' );

Dark pool orders are not considered since they're not visible on the order book.

market_price

Returns a volume-weighted USD price per BTC based on MtGox trades within the last 24 hours. Returns undef if there have been no trades in the last 24 hours.

version

Returns a string indicating which version of the MtGox API is being used. One of 'legacy' or 'v0' (depending on which authentication was provided to "new").
