IDC Core features Harmony patches that enable each trader to use a separate currency. To make use of this feature, a trader must be given a specific currency different than the global currency to use. There are multiple ways to specify the currency for a trader.

The first method is to modify traders.xml manually and add the currency_item attribute to the traders corresponding trader_info entry.

<trader_info id="6" reset_interval="3" open_time="6:05" close_time="21:50" currency_item="<item name>">

The second and ideal way is to use xpath to add the attribute to the trader's trader_info entry.

<setattribute xpath="traders/trader_info[@id='<trader id>']" name="currency_item"><item name></setattribute>
