When exactly is this? When I stop accepting bids or have done all trades? I think the former makes most sense.
What happens if a bidder doesn't pay? Should there be a time limit after participants have been asked for payment after which the next bidder gets the chance, or do I abandon the bid? 48 hours? Three days?
Please advice on length of auction, i.e. how long I will accept bids. 3–7 days? 4 days?
4 days bidding, 2 days payment window, 1 day for next calculation (if the auction results affect that), and repeat?
I wish to begin the auction soon, of course, but want most of the procedure figured out first. Almost there, I think.
