Updated (2021)

Here is a custom function with a SQL query that will return the products "instock" count:

function get_instock_products_count(){
    global $wpdb;

    // The SQL query
    $result = $wpdb->get_var( "
        SELECT COUNT(p.ID)
        FROM {$wpdb->prefix}posts as p
        INNER JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
        WHERE p.post_type LIKE '%product%'
        AND p.post_status = 'publish'
        AND pm.meta_key = '_stock_status'
        AND pm.meta_value = 'instock'
    " );
    
    return reset($result);
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested and working

Usage example (in any php file):

$count = get_instock_products_count();
$message = sprintf( __( 'Hurry Up! Only %s remaining trades' ), $count );
echo '<div class="woocommerce-message">'.$message.'</div>';

will display something like:
