Online auctions are time-sensitive by definition. The bid count changes, your maximum bid can be outbid, and auctions end at exact moments that require you to be paying attention. Auto refresh automates the monitoring so you don't have to manually refresh the page every minute for hours.
This guide covers the platform-specific strategies for using auto refresh effectively across the major online auction sites.
Platform-by-Platform Guide
eBay
eBay auction pages do not automatically update bid counts or current prices — the page shows a static snapshot of when it loaded. Auto refresh at 2-minute intervals during the final hour keeps current pricing accurate. EBay's proxy bidding system means the current price shown is the second-highest bidder's maximum plus one increment — not the winner's true maximum. Use eBay's built-in "Watch" feature plus auto refresh together: the Watch notification tells you when you've been outbid, and auto refresh keeps the price current.
Catawiki
Catawiki is a European specialty auction house (art, collectibles, watches) with a 3-minute extension rule: any bid in the final 3 minutes extends the auction by 3 more minutes. This makes last-second sniping impossible but also means competitive auctions can run past their listed end time. Monitor at 30-60 second intervals from 30 minutes before the listed end time, and be prepared to keep watching as the auction potentially extends multiple times.
Invaluable / LiveAuctioneers
These platforms host live auctioneers running real-time sales. During the live event, bids update in real-time through their platform interface — auto refresh is not applicable during live sessions. However, for absentee bids and pre-bid monitoring, auto refresh on your watching page confirms current leading bids before the live session begins.
ShopGoodwill
ShopGoodwill is classic FCFS auction format with a hard end time and no bid extension. Pages do not auto-update. Monitoring at 2-minute intervals in the final hour is standard. ShopGoodwill uses "last 10 minutes" extension only if bids arrive in that window — check specific listings as rules vary. True last-second bidding is viable here.
Government surplus auctions (GSA, publicsurplus.com)
Government auction sites typically use timed endings with extension rules. Pages are often slow to load and static. Auto refresh at 1-2 minute intervals in the final hour helps track competitive bidding. Payment and removal deadlines on these items are strict — research thoroughly before bidding.
Copart / IAAI (Auto auctions)
Vehicle salvage auctions at Copart and IAAI use real-time live interfaces that update automatically during active bidding. Auto refresh is less relevant during the live bidding window. Use it during the pre-bidding period to monitor current bids before the live session opens.

| Time Before Auction End | Recommended Interval | What to Watch For |
|---|---|---|
| 24+ hours | 1-2 hours | First bid activity, significant price jumps |
| 2-24 hours | 30 minutes | Competition level building up |
| 30-120 minutes | 2-5 minutes | Late bidding activity, current price trend |
| 10-30 minutes | 60 seconds | Active bidding; decide if still within budget |
| 2-10 minutes | 15-30 seconds | Final competition; preparing your bid |
| Final 60 seconds | Manual refresh or 5-10 seconds | Last-second bid placement for eBay/ShopGoodwill |
Understanding eBay's Proxy Bidding System
Many buyers don't understand that eBay uses a proxy (automatic) bidding system. When you bid $50 on an item currently at $10 with a $1 increment, eBay doesn't show $50 as the current price — it shows $11, the minimum needed to beat any previous bidder. If another buyer bids $30, eBay automatically raises your bid to $31 without you doing anything. You only lose if someone bids more than your maximum of $50.
This means refreshing faster to "monitor" the current price is somewhat misleading — the important number is your maximum bid, not the current displayed price. Auto refresh is most useful for checking whether you've been outbid (current price exceeded your maximum) and for the psychological aspect of watching how competitive an item is becoming.
Multi-Tab Auction Monitoring
When tracking multiple auctions ending at similar times, open each in its own tab and set individual refresh intervals. Auto Refresh Ultra manages multiple tabs independently — each runs its own timer without affecting the others.
For 3-5 simultaneous auctions in their final 30 minutes:
- Open each auction in a separate tab
- Set 60-second refresh on each
- Arrange tabs in a grid view (Chrome: drag tabs to new window, then Snap layouts)
- Monitor all simultaneously; make bid decisions on each independently

Get Auto Refresh Ultra FreeFrequently Asked Questions
Can auto refresh help me win eBay auctions?
It helps you monitor current pricing accurately, but eBay's proxy bidding system means the winner is determined by maximum bid amounts. The strongest winning strategy is bid sniping — placing your maximum bid in the final 10-15 seconds — combined with auto refresh to stay informed of current prices leading up to that moment.
What is the best refresh interval for monitoring auctions?
5-10 minutes for early monitoring; 2-5 minutes in the final hour; 60 seconds in the final 30 minutes; 10-15 seconds in the final 5 minutes. Manual refresh in the final 60 seconds if you're sniping.
Does Catawiki use live bidding or timed endings?
Catawiki uses timed endings with a 3-minute extension rule — any bid in the final 3 minutes extends the auction. This means active auctions often run well past their listed end time. Monitor continuously in the final 30 minutes at 30-60 second intervals.
Can I monitor multiple auctions ending at the same time?
Yes. Auto Refresh Ultra runs independent refresh timers on each tab. Open multiple auctions, set intervals per tab, and monitor all simultaneously with a multi-window setup.
What auction sites benefit most from auto refresh?
Sites with static pages that don't auto-update bid counts: eBay, Catawiki, ShopGoodwill, Invaluable (pre-bid monitoring), and government surplus auctions. Sites with real-time interfaces (Copart, IAAI during live bidding) don't need auto refresh during active sessions.
