Custom Taxonomy Theme

Hey there, i have a Custom Taxonomy Theme (taxonomy-listing_category.php) and it displays ALL of my listings, is their a way to make this only display the active slug being viewed?

like i have categories of test1 test2 test3 i want a way to show only the results of the /listing_category/test1/ to be shown when there and the /listing_category/test2/ items to be displayed when on test2 category page

<?php get_header();
$args = array(
    'post_type' => 'listing',
    'orderby'=>'title',
    'order'=>'ASC',
    'post_status' => 'publish',
    'posts_per_page' => 20 );
?>
<table class="second">
    <tr>
        <td>Company Name</td>
        <td>Company Profile</td>
        <td>Country</td>
        <td>City</td>
    </tr>
<?php      $loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
?>
    <?php
    $x++;
    $color = ($x%2 == 0)? 'bg1' : 'bg2';
    echo '<tr class="' .$color. '">';
    ?>
    <td width="15%" class="td2"><a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a></td>
    <td width="15%" class="td2"><?php  echo directory_listing_get_meta( 'directory_listing_company_profile' ); ?></td>
    <td class="td2"><?php  echo directory_listing_get_meta( 'directory_listing_country' ); ?> </td>
    <td width="15%" class="td2"><?php  echo directory_listing_get_meta( 'directory_listing_city' ); ?></td>
    </tr>
<?php
endwhile;
echo '</table>';
wp_reset_query();
get_footer();
