exclude custom post type by meta key in wp_query

If you don’t use any other meta data, just add the following to your $args:

'meta_key' => 'sold',
'meta_value' => true, // or whatever it is you're using here
'meta_compare' => '!=',

Otherwise, use a WP_Meta_Query:

'meta_query' => array(
    array(
        'key' => 'sold',
        'value' => true,  // or whatever it is you're using here
        'compare' => 'NOT LIKE',
    ),
),
