<chapter id="chapter_currency">
  <title>Multiple Currencies</title>

  <para>This chapter will show how to set up &app; accounts to use multiple currencies.
  </para>

  <sect1 id="currency_concepts1">
    <title>Basic Concepts</title>

    <para>&app; supports over a hundred currencies, from the Andorran Franc to the Zimbabwe Dollar. For
      example, you can have a bank account set up in Euros, and another using Hong Kong Dollars.
    </para>

    <para>Some of the issues which arise when using multiple currencies are as follows:
    <itemizedlist>
        <listitem><simpara>How do you transfer funds between accounts with different currencies?</simpara></listitem>
        <listitem><simpara>How do you calculate the overall value when you have mixed currency accounts?</simpara></listitem>
        <listitem><simpara>How do reports deal with mixed currencies?</simpara></listitem>
      </itemizedlist>
    </para>

    <para>You can either deal with multiple currencies using manually entered transactions to record currency
      gains and losses as described in <xref linkend="currency_manual" /> or you can utilize
      currency trading accounts introduced with &app; version 2.3.14 to automatically record the
      gains and losses on transactions between currencies as described in the subsequent section.
      Trading accounts are not enabled by default in &app; and must be explicitly enabled as
      described in <xref linkend="currency_trading_accts" />.
    </para>
<!-- TODO: add sections
    <para>The following sections are common to both manually recording gains
      and losses from multiple currency transactions and using trading accounts
      to record such gains and losses.</para>
TODO -->
  </sect1>

  <sect1 id="currency_manual">
    <title>Manually Recording Currency Transaction</title>

    <sect2 id="currency_acct1">
      <title>Account Setup</title>

      <para>Your default account currency is set in the <guilabel>Account</guilabel> tab under
        <menuchoice>
          <guimenu>Edit</guimenu><guimenuitem>Preferences</guimenuitem>
        </menuchoice>
        (
        <menuchoice>
          <guimenu>&appname;</guimenu><guimenuitem>Preferences</guimenuitem>
        </menuchoice>
        on &mac;).
      </para>

      <para>Similarly, &app; offers an option to set your preferred currency for displaying reports (like the
        balance sheet and income statement). The option is called <guilabel>Default Report
        Currency</guilabel>, and is in the <guilabel>Reports</guilabel> tab of the
        <guilabel>&appname; Preferences</guilabel> screen. You&rsquo;ll want to set both options
        when you start using &app; because if (for example) your accounts are all in Canadian
        Dollars but the generated reports are all in US Dollars, the reports will just say that
        there are <quote><computeroutput>no data/transactions (or only zeroes) for the selected time period</computeroutput></quote>.
      </para>

      <para>When you create a new account, you have the option to define the commodity in which that account is
        denominated. For accounts denominated in a currency, you can specify any of the currencies
        supported by &app; by simply selecting it from the currency commodity list. You will notice
        that the default currency is the currency that is defined for the parent account of the new
        account.
      </para>

      <para>As an example, let&rsquo;s set up a bank account scenario where you mostly work in US Dollars, but
        do also have a European bank account using the Euro currency, as well as one bank account in
        Hong Kong using Hong Kong Dollars. So, set up 3 bank accounts, one denominated in US
        Dollars, one using Euros, and the third in Hong Kong Dollars. One possible account structure
        for this would be:
      </para>
<screen>
-Assets (USD)
   -Current Assets (USD)
      -US Bank (USD)
      -European Bank (EUR)
      -HK Bank (HKD)
-Equity (USD)
   -Opening Balances (USD)
      -USD (USD)
      -EUR (EUR)
      -HKD (HKD)</screen>
      <note>
        <para>The currency of each account is shown in parenthesis.
        </para>
      </note>

      <para>Since in this example you mostly work in USD, all of the parent accounts are set to USD. Of course,
        if you mostly work in Euros, you could change the currency of these parent accounts to EUR.
        The totals shown in the account tree window will always be converted to the currency of each
        particular account. Notice, we also set up 3 Opening Balances equity accounts, used to
        initially populate the 3 banks.
      </para>

      <note>
        <para>You could also set up just a single Opening Balance account and use a currency transfer to populate
          the <quote>different currency</quote> accounts. However, this is more advanced option,
          which is explained in a later section (<xref linkend="currency_purchase2" />).
        </para>
      </note>

      <para>Below you see the result of this example, in which you start with 10,000 USD, 10,000 EUR as well as
        10,000 HKD in the three bank accounts. Notice that the total of the parent accounts only
        shows the value of the currency of sub-accounts with matching currencies. In other words,
        the Total Assets and Total Equity values only reflect USD amounts, because &app; has no way
        of evaluating the value of EUR or HKD yet. Once you set up exchange rates between the
        currencies, the parent accounts will calculate the converted value of all sub-accounts. See
        the later section (<xref linkend="currency_howto1" />) on ways to do this.
      </para>

      <sect3 id="currency_acct_user2">
        <title>User-Defined Currencies</title>

        <para>Usually when we talk about currencies, we mean government-backed currencies (or more precisely,
          currencies defined in <ulink url="&url-wp-en;ISO_4217">ISO 4217</ulink>). &app;
          does not allow you to create your own currencies. If you want to track
          non-<acronym>ISO</acronym> currencies, you can use either of two workarounds, depending on
          which fits your needs better.

        <orderedlist>
        <title>User-Defined Currencies Workarounds</title>
        <para>Let&rsquo;s say for example that you want to track loyalty points you&rsquo;ve earned by buying from
            a certain group of businesses. The account which tracks your loyalty points will be
            <emphasis>Assets:Other:LoyaltyPoints</emphasis>.
        </para>
        <listitem><simpara>
            Treat these as if they were a security&mdash;that is, like a stock or mutual fund.
            </simpara>
	        <para>
            In this workaround, you define a new security, of type <guilabel>FUND</guilabel>, called
            LoyalityPoints. This is pretty straightforward&mdash;when you create the new
            <emphasis>LoyaltyPoints</emphasis> account, just set the account type to
            <guilabel>Stock</guilabel> or <guilabel>Mutual Fund</guilabel>, click the
            <guibutton>Select...</guibutton> button next to the
            <guilabel>Security/currency:</guilabel> box, and click <guibutton>New</guibutton> to
            define a new security of type <guilabel>FUND</guilabel>.
            </para>
            <para>
            This is not really what the stock and mutual fund account types are meant for, but &app; will allow
            it. The downside is that you&rsquo;ll have to enter a <quote>price</quote> for every
            transaction involving this account, because &app; needs the prices to figure out the
            monetary value of the points and treat them as one of your assets.
            </para>
        </listitem>

        <listitem><simpara>
            Use one of the <quote>dummy</quote> currencies for them.
            </simpara>
            <para>In this workaround, you use one of the dummy currencies to
            track the loyalty points. These currencies are <quote>XTS (Code for testing
            purposes)</quote> and <quote>XXX (No currency)</quote>. If you use one of these for your
            LoyaltyPoints account, you can enter transactions into the account without
            having to enter share prices for every transaction. And, you can keep using the same two
            dummy currencies to track all sorts of amounts&mdash;vacation dollars earned and used so
            far this year, vacation hours earned and used, health insurance benefits allowance used
            and remaining, and so on.
            </para>
            <para>The drawback with this workaround is that you cannot define exchange rates for the dummy
            currencies to convert them to <acronym>ISO</acronym> currencies. If you want to do that,
            you really should use the first workaround.

      <title>Recording and Updating Currency Exchange Rates</title>

      <para>&app; allows you to update the Currency Exchange Rates both manually and automatically. This process
        is essentially the same as setting share prices for investments (see
        <xref linkend="invest-stockprice1"/>). In the following two sections we will work through
        both methods.

      <title>Trading Account Concepts</title>

      <para>In accounting terms, trading accounts are specialized equity accounts to record changes in income
        which result from transactions between two or more currencies. In &app; they are implemented
        as a top level account type of Trading. When trading accounts are enabled the required sub
        accounts of Trading are automatically created if they do not already exist when a
        transaction between one or more currencies is created.
      </para>

      <para>In the extended Accounting Equation, Trading accounts would appear as follows:
        <equation>
          <mathphrase>Assets = Liabilities + Equity (+ Income -Expenses) + Trading </mathphrase>

      <caution>
        <para>The user is prevented from manually making entries directly to the registers for any of the accounts
          in the Trading top level account group. All entries to these accounts are automatically
          generated when transactions between currencies are created in other account registers
          within the &app; account hierarchy.
