# Bid Extension For Bidders (updated)
Some bidders will try to use a strategy of placing a bid exceeding the current highest bid as late as possible before the item end time. This is usually seconds before the end of the auction with the idea of not giving other bidders time to outbid them.
The Bid Extension Rules, when enabled in Auctria, are meant to help prevent this kind of strategy from potentially minimizing the highest bid your participants may actually be willing to make. These rules help bidders by giving all bidders additional time to help support the fundraiser with a higher bid.
It is generally considered good form to post on the auction website in an obvious place if Bid Extension rules are in place and what those rules are.
Please check with your event Organizer for the specifics of the Bid Extension rules they are using, if any, and for any additional explanation as needed.
# Proxy Bidding And Bid Extension
By default, the option for Proxy Bidding is enabled for auctions. If a Proxy Bid is made during the Bid Extension window it will be honored as the Bid Extension rules are purely an extension of time.
If a Proxy Bid exists for an item, it will trigger the Bid Extension rules whenever another bidder places a bid during the Bid Extension window of time.
