Position is a function of one number and nothing else. No algorithm, no votes, no editorial picks.
Pay any whole-dollar amount and you land wherever that amount places you. You do not have to beat the top bid to get on the board.
To take a rank someone holds, pay $1 above them. Ties go to whoever paid first.
A listing appears once the payment has actually settled, and a refund removes it. Nothing is held in reserve and nothing is promised.
Paying is the only thing that puts you on the board, so there is nothing to log in to and nothing to cancel.
