The system will remember the “High Water Mark” of any bids you make until the bid is completely fulfilled or cancelled.
“High Water Mark” means that the system will remember the original bid, even if you don’t have the available funds to fulfill all of it. This lets bidders increase available funds to fulfill bids made, allowing you to keep your bid, add funds to your account and have multiple bids fulfilled. This allows you to take your view on multiple properties. See examples outlined in the section explaining Scale Down for further detail.
