When selling to the market, instead of putting a big bulk of a finished product 
(which you might need for an order)in, put in 1-by-1. And every time the product
is bought and the market number goes back to 0, put in another 1. That way, when
market demand takes a plunge, you wouldn't have 20 of that product cooped up 
waiting for another big boost in demand when it could have been used to help 
you complete an order.
