Auction rules: listings, durations, increments and anti-sniping
The Auction rules tab decides how your marketplace works: who can sell, what needs approval, which features are on, how long auctions run and how bidding steps up.

Anti-sniping
Anti-sniping window (minutes): a bid placed in the last X minutes extends the auction. Extend by (minutes): how much. With 2 and 2, a bid at 1:30 before the end gives everybody two more minutes. 0 = off. See Anti-sniping.
Bid increments
One line per price level in the format from:increment:
0:1
100:5
500:10
1000:25
2500:50
5000:100
10000:250
Line 100:5 means: from a current bid of 100, the next bid must be at least 5 higher.
Maximum bid protection
Maximum bid multiplier protects against typos: a bid can not exceed the next minimum bid multiplied by this value. With 10 and a minimum bid of $105, the highest accepted bid is $1,050. 0 = no limit.
