Basically this is the wrong way to go about playing the game anyway. The fun is in attempting to predict fluctuations in price without influencing it. Delivery of prizes depends on the timely provision of a mailing address. The top player at the end of the game will receive an exciting actual prize, but its delivery requires the provision of a valid mailing address. Unless you provide a valid mailing address at the end of the game, your prize cannot be delivered to you.
Tiebreakers extend the game.
In the event of a tie, the game will continue longer than the posted ending date for as many days as it takes to break the tie. At that point, the person ahead is the winner. However, other players may not use that time to get ahead. During the tiebreaker part of the game, only those involved in the tie may continue to compete. The game is over for everyone else.
