[Solved]Top Sales.

Yes it's possible.

In your module's hikashop options, change the option "ordering field" to "product_sales" and the option "ordering direction" to "descending".

There are no options for all that. You will have to edit the layout file that you're using on your products listing ( it's by default listing_img_title ) via the menu Display->Views and change the code there to display the additional information you need.

For the sales the code will be:
<?php echo $this->row->product_sales; ?>

For the quantity the code will be:
<?php echo $this->row->product_quantity; ?>

For the rank the code will be:
<?php static $rank =0; $rank++; echo $rank; ?>
