You just need to run this SQL query
Code:
INSERT INTO `xcart_config` (`name`, `comment`, `value`, `category`, `orderby`, `type`, `defvalue`, `variants`, `validation`) VALUES ('currency_sign', 'When checked, shows currency sign before price', 'N', 'Appearance', '450', 'checkbox', 'N', '', '');
Now you have this option in appearance section at the very bottom of page.
And here is currency.tpl
Code:
{* $Id: currency.tpl,v 1.13.2.1 2006/04/29 06:36:56 max Exp $ *}
{if $plain_text_message eq ""}<span style="WHITE-SPACE: nowrap">{/if}{if $display_sign}{if $value gte 0}+{else}-{/if}{/if}{if $config.Appearance.currency_sign eq "Y"}{$config.General.currency_symbol}{/if}{$value|abs_value|formatprice}{if $config.Appearance.currency_sign ne "Y"}{$config.General.currency_symbol}{/if}{if $plain_text_message eq ""}</span>{/if}
