Anti-Sniping 5-Minute Auto-Extension Mechanism
To ensure fair competition and eliminate unfair advantage caused by last-second internet bandwidth manipulation (bid sniping), the e-Auction platform enforces an automated dynamic extension system.
If a valid, higher bid is received within the final 5 minutes (300 seconds) of an active auction schedule, the closing timer shall instantly and automatically extend by exactly 5 minutes from the timestamp of the new bid.
Successive bids submitted during any extension period will continuously reset the remaining time to 5 minutes until a full 5-minute countdown elapses with zero competing bids.
The server clock synchronized with Bangladesh Standard Time (BST via NTP) is the sole legal authority for bid timestamp determination.
- •Auto-extension applies to both single-lot and multi-lot independent bidding windows.
- •Client-side timer differences due to local device lag do not affect server-side auto-extension execution.
