Auction types and the trading room
Four sale models for every seller, and bidding tools designed to discover the fair and true price of the property.
Four types of auctions
Two axes determine the type: price visibility (hidden versus public) and seller assurance (conditional versus absolute).
Open auction
All bids are visible to everyone in real time. It creates the highest levels of competition and transparency — the ideal option for high-demand properties.
Public price • Open competitionReserve auction
A hidden (secret) minimum price set by the seller. The property is sold only if the highest bid exceeds it — the safest option for a seller careful about the property's value.
Seller protection • Most commonAbsolute auction
There is no reserve price — the property is sold to the highest bidder whatever the amount. It creates maximum urgency and demand, and guarantees a sale.
Guaranteed sale • Maximum urgencySealed bids
Bids are hidden from everyone until the end, and the winner is announced after closing. Ideal for sensitive transactions and institutional buyers.
Complete secrecy • One serious bidAnatomy of the auction screen
Status bar
A precise server-synchronised countdown — no room for timing differences. Colours change by status: red for live and purple for extended.
Bid history
A live chronological feed of all previous bids, highlighting encrypted bidder identities (Bidder_X, Bidder_Y...) — complete transparency without revealing identities.
Control panel
Quick-bid buttons (+5K / +10K / +50K) and one-click activation of automatic bidding (Auto-Bid).
No place for last-minute bids
The problem with traditional auctions: Last-minute robots place a bid at 00:00:01 and steal the auction, frustrating buyers and reducing final value.
Kemebid's solution: Any bid in the final 5 minutes automatically pushes the end time forward — everyone gets a chance to respond and the seller gets the best price.
⏱️ We guarantee discovery of the property's fair and true price by allowing competitive responses from everyone, with a maximum of 3 extensions.
How recursive Auto-Bid works
User (A) sets a maximum
Example: an automatic bidding maximum of EGP 2.0 million — and leaves the screen reassured.
User (B) bids manually
Enters with a bid of EGP 1.8 million trying to move ahead.
The system responds immediately for (A)
It adds only the minimum increment — in fractions of a second — to protect (A)'s position at the lowest possible cost.
The cycle continues automatically
Until one party reaches their maximum or withdraws.
🛡️ Program constraint: server stability is protected by a maximum programming depth to prevent infinite loops.
