from 5.06 to 5.15, the orders will be matched as well, so the final status of your order will reflect after 5.15(sometimes earlier if the price already moved)
however, from 5.00 to 5.05 you can put all orders there,
sometimes, buy at a very high price just to make sure it is done, and it will be matched with lower price even your bid is high.
