Topic: How to bid lowest necessary bid

“… my recollection is that I had program that bid only the amount necessary to win, up to my maximum bid. Thus if the high bid was $20 and I was willing to pay $30, I would submit a bid of $30 to my program but if the high bid just before close was $24, the program would bid me at $25 and I would win….”

In a traditional outcry auction the person who is prepared to bid highest will win. Ebay auctions are somewhat different in that they are time-limited, so the person who makes the highest bid BEFORE THE END-TIME will win. And they have increments, which can result in a non-intuitive result in sniping…

You can always win an auction by posting a very high figure well before the end of the auction, but it has to be very high – well above what EVERYONE else thinks it is worth. This might have to be very high indeed if you are in a bidding war with collectors. If you bid a more sensible high figure well before, your opponent bidders can increment their bidding slightly, watch your automatic response, and increment again until they are just over your figure. To avoid this it is a good idea to make your ‘high bid’ very shortly before the end of the auction, giving them less time to ratchet the price up. This is what Jbidwatcher is for.

Note that you do NOT want to put your high bid in as close to the end of the auction as possible. You want to put it in at the EARLIEST point when no one can respond – probably about 5-8 seconds before the end. This is because Ebay does automatic bids in increments.

For example, let us say that you and an opponent both value an item at $100, and that at $100 the bid increments are $10. You are going to bid $95, and your opponent is going to bid $98. So he should win, and he would win if you both submitted your bids with 10 minutes to go, when the item was displayed at $20.

In the last 10 minutes the item price goes up, as other bidders snipe. At 10 seconds to go, it is displayed at $83, because someone has bid $90. You put your snipe bid of $95 in with 6 seconds to go, and the displayed price goes up to $93 (because of the $10 increment). At that point the only next bid that can be accepted is a bid of $103 or above. Your opponent submits his snipe bid of $98 (higher than yours) at 4 seconds to go, and is rejected. You have won the item at $93, when your bid was $95, and your opponent has lost even though he was willing to pay more. Because he was just behind you in the bidding.

I think that this is what happens in a number of cases where people complain that they failed to win even though they bid higher. The lesson is clear – don’t aim at bidding 1 second before the end – aim at bidding about 6-7 seconds before the end….

Topic: Option to archive and not load archived auctions

Greetings,
Well…yeah, I got an email recently from someone who’s complaining it takes HOURS to launch JBidwatcher. Unfortunately the reason is that their database contains 1.4 million auction entries, and JBidwatcher tries to do some joins on that data early on.

So…man, I could go for hours about the stuff that’s built up in JBidwatcher over the years, and the cruft that’s in the database right now. (For example, it doesn’t delete old [auctions] rows, so they stack up, even though nothing refers to them anymore.) My 3.0 version intends to significantly reduce that, by not creating a new [auctions] row for each update. That’s how it works in the 2.x series, it creates a new row and moves the [entries] foreign key reference to the new row. It used to delete the old one, but something broke and it started deleting active rows, so I turned off deletion until I could fix the deeper issues.

If you use the Derby database, you can do some really straightforward operations directly from Derby’s own interactive console. The derby username and password are ‘user1’. (This isn’t particularly intended to be secure as it requires access to your box to get to anyway, and the username and password are in the clear in the source code.)

Personally I hate all GUI database browsers; they’re all terrible, unintuitive, and crashy. That said, you could use Squirrel SQL to browse and issue SQL commands. Speaking as a Mac user (if you need Windows or Linux help, I can give it), first go to the Drivers, and add derby.jar from JBidwatcher.app’s own directory (Contents/Resources/Java/derby.jar) as an Extra Class Path for Embedded Derby. Then create an Alias, using jdbc:derby:/Users/{username}/Library/Preferences/JBidwatcher/jbdb as the database, and user1 as both username and password. A test should be successful. Hit OK, and Connect.

Switch over to the SQL tab, and type SELECT * FROM auctions; and press Ctrl-Enter. That’ll query your [auctions] table. Similarly SELECT * FROM entries; will query your entries table.

You could do something like:

CREATE TABLE ARCHIVED AS SELECT * FROM auctions WITH NO DATA;
INSERT INTO ARCHIVED SELECT * FROM auctions;
CREATE TABLE ENTRY_ARCHIVED AS SELECT * FROM entries WITH NO DATA;
INSERT INTO ENTRY_ARCHIVED SELECT * FROM entries;

to copy everything in the existing [auctions] and [entries] tables to an [archived] table equivalent which JBidwatcher won’t ever touch (because it doesn’t know about it). Then something like

DELETE FROM auctions WHERE created_at < '2014-12-23 00:00:00.0';
DELETE FROM entries WHERE auction_id NOT IN (select id from auctions);

to prune to the most recent listings. (In that case, ever since the night before the night before Christmas.)

The key understanding here is that an Auction is everything that comes from the server. The information isn’t added by the user, or JBidwatcher, or anything like that, it’s what we glean from eBay’s listing pages. The Entry is everything around it, overridden shipping price, last bid amount, category, snipe info, etc…

I had some ideas for archiving auctions, but they never came to fruition, so it’s not terribly helpful right now. My hope is that with the 3.0 branch I’m working on, I’ll be better able to do a lot of this, especially as I’m moving vast amounts of the database logic down into the scripting layer. We’ll see…

In any case, back up your stuff, seriously, before doing any of that.

It’ll probably be easier in the 3.0 version to do database operations, as it has the whole Scripting Manager interface which is AweSome. :)

Topic: How to bid lowest necessary bid

Greetings,
Yep; I have known people to go ‘nuclear’, where they bid an ABSURDLY high amount, under the theory that they’ll definitely get the item, although it might be at an exorbitant price. (This is only, obviously, for extremely rare items.) The fatal flaw there is that if two bidders decide to snipe ‘nuclear’, then a $100 item might end up going for thousands of dollars.

So don’t do that. :)

But yes, eBay’s system is designed so the resultant winning bid will be anywhere from a penny to one minimum bid increment over the previous bid. (There’s a caveat, which is that if you’re the first bidder at $20, and someone snipes $20 at the end of the auction, as the early bidder, your equivalent bid takes precedence. This is why, as a sniper, you always want to perturb your snipe bid by a few cents. Because if the current price is (e.g.) $15, and you bid $20.01 and the hidden proxy high bid is $20, then you’ll be the high bidder, but if you bid $20, they will.

So, no matter what amount I bid, if I am the winning bid I will pay from 1 cent up to and including the amount of the incremental bid over the amount of the second highest bid, but never any more.

Topic: How to bid lowest necessary bid

Yes, eBay does that for us…. and thanks to that… coz one time my snipe amount of $30.00 was missing the decimal point and my snipe went out at $3,000.00 but luckily I won the auction at $27 with change. :-D

JBW works well for me, and I am still bidding and winning. Having fun doing that I do all day and getting “surprise” notices when JBW wins anything for me on my lists. Thanks

Topic: How to bid lowest necessary bid

Greetings,
This is a common misconception from folks watching ‘open outcry’ auctions, where the amount you bid IS the amount you pay, period. (Having spent a lot of money on these in my youth at science fiction conventions, I’m also very familiar with the idea.)

What YOU are describing as a ‘program’ is the fundamental way that eBay works. If the current high bidder’s maximum bid is $20 and you place a bid with eBay for $30, the price does not immediately become $30. Instead, it uses something called a ‘highest bidder, second price’ system, which essentially says, ‘The highest bidder will be the person marked as winning, but the price they are set at is one minimum bid increment over the second highest bidder’s price.’ There are some deep auction-theoretic reasons why this system works (as in, William Vickrey received a Nobel-related prize for their work on auctions and bidding games that led to this system) but fundamentally that’s how eBay works.

So JBidwatcher doesn’t mess with that. It bids your amount at the last moments of the auction, and lets eBay sort out the high bidders and second prices.

So if you’re looking at an item that has a current high bid of $24, the high bidder may have placed an actual bid of $150. Nobody knows except eBay. So if JBidwatcher tried to do what you’re describing, and placed a ‘minimum bid increment up’ bid of $25, you would lose the auction, because eBay’s automatic proxy system would bump the other user’s bid up to $26: one minimum bid increment over the next highest bidder (yours).

All this complexity is simplified in that you don’t need to worry about it; JBidwatcher places the full bid in the last seconds, but you will never pay more than one minimum bid increment over the next-highest-bidder’s price. Because that’s how eBay does it.

I have not used a sniping program in years, but my recollection is that I had program that bid only the amount necessary to win, up to my maximum bid. Thus if the high bid was $20 and I was willing to pay $30, I would submit a bid of $30 to my program but if the high bid just before close was $24, the program would bid me at $25 and I would win.

Is there a term for this kind of bidding? Is it available with jbidwatcher? If not what programs do have it available?

Thanks for your answers.

Topic: Option to delete auctions over x weeks old

Yes, would be nice. But since it’s not a build in feature, so I opt to delete all my db and start with a fresh one as I had too many in db and it’s making launching the JBW slow

I started from scratch and just updated my ebay items, and it’s running smooth and fast …. and I now constantly delete all the old ones…… Whatever is past, is history…. besides, I can always find the same info in my email database… (if I ever need to look up an item I bought a year ago, or 9 months ago)…. that’s my way of making jBW still a lean trim machine and bid and win for me everyday.

Have fun with life guys…. Happy snipping now… :-D

It would be nice if JBidwatcher could be set to delete old auctions after a suitable interval as the db gets very full.

Hi Morgan,

Hope you and yours are all fine!

JBW: I’m running 2.5.3pre3-2-g03a9bc3 on Win 8.0, (Ebay.co.uk Java 7.45) and it’s mostly fine.
OK, there are the problems with missing shipping details, and the thumbnails, but they can be worked around.

My main problem is that JBW seems to shut itself down at random times (anywhere from an hour up to a day or so) for no apparent reason.

There’s nothing unusual running on the laptop, no malware, no weird scheduled tasks.

Thought I’d mention it.

Cheers

Rog.

You might need more than 40-50 seconds if your Mac falls to a deep sleep…… takes time to wake and start spinning disc, attempt to connect to internet dealing with WiFi protocol etc….. so I would say 1.5-2 min. to be safe if you want to do any programming.

I see (FP) in every auction, although the price is not fixed (e.g. item 121220517850). It occurs for a long time now, so I couldn’t snipe using JBidwatcher since some months. JBidWatcher 2.5.3pre4 is running unter Linux (openSUSE 13.1, up-to-date, java 1.7.0_45). Configured country site is ebay.de
Is there a way to repair the auction data base manually, configure any setting, or do I have to wait for JBidwatcher to be fixed?

Topic: [PreRelease] JBidwatcher 2.5.3pre4

10.9 wake issues are talked about on many places including Apple Support forum.

I am trying to setup 10.9 and try, but as I posted many times before, my setup with an iMac @ 10.6.8 and pre3 works good for me and …

I keep iTunes playing all my music continuously (volume down to minimum or mute), and keep display to dim and eventually my screen will go blank, but music is going and somewhat trustworthy cable internet connection with a snipe time of 8 sec. works well so far for me.

No software package is perfect not mentioning eBay has hundreds of droids working on modifying the scripts and thousand of servers (hardware may act up?)…. but if it works, or you can make it work for you, then it’s a good solution.

I am still winning my share of bids assuming I want to bid high enough, but mostly I set a moderate price and if I win, I am always happy.

That’s my strategy…. I kept the 10.6.8 because of JBW and 2 other programs I must use and 1 of my favorite game, and I do have the luxury of other Mac OS machines, so it’s working for me this way for now……

But do read up about the wake issues on 10.9 which I think I will encounter when I setup 10.9, but who knows, 10.9.1 will be out soon as usual, the first version is somewhat buggy such as the wake was never encounter in Apple lab I suppose they just keep those test machine running all days….

Good luck.

Hello Morgan,

I hope you do check posts (even if you can’t respond to each individual posts).
One widespread problem that you will notice is no matter which version of JBidwatcher we are running on OS X 10.9 is that bids don’t fire!
After going through many settings, going through the forum and faq’s and losing 5 auctions (as a test, in all instances, snipes did not fire).

The problem seems to be Energy Saver settings!
In 10.8, snipes fired spot on with Energy Saver settings set to-> Computer Sleep:Never ; Display Sleep: 15 minutes ; Put hard disk to sleep when possible : unchecked (disable)

In 10.9, with these same settings, snipes do NOT work. The log entry consistent with every failure: The computer may have slept through the snipe time

Also, in 10.8, moving a mouse would “wake” the screen. In 10.9 moving a mouse does not wake the screen. Only pressing a key wakes the screen. Could this have anything to do with snipes not firing?

Now, I am talking about an iMac…not a laptop so the lid is not shut or anything. It is running with above settings. Just can’t figure out how to prevent computer from going to sleep (or why is it going to sleep in the first place!)

Is it not possible for JBidwatcher to “wake” the computer 40-50 seconds BEFORE executing the snipe? Once a computer is awake 40-50 seconds before snipe execution atleast snipe can’t fail because of sleep!

Any ideas? Suggestion? scripts?

Mine shows too all as (FP) since 8 days, 10.6.8 pre3.

But the older work around is still working:

Configuration manager -> General / Doubleclick settings -> action: initiate a snipe on a given action

In JBWatcher you can snipe by double clicking on the item.

So I fixed the forum, but I found an annoying bug in non-US auctions in JBidwatcher which is delaying the release. (It’s showing bid counts for auctions as ‘0’, no matter what they actually are.)

I know what’s wrong, but fixing it is taking a little bit.

Apologies for using this forum but the ‘help’ forum has an error if you try to start a new topic.

I am having a strange problem with the latest version of jbidwatcher. I use alt/tab to move through the windows that are open on my laptop and have always used this shortcut. If I do it with jbidwatcher open, it immediately crashes and I have to re-boot to get it loaded again. Would appreciate any advice as have been using jbidwatcher for a couple of years and this has never happened before. I am using Windows 7. I have just upgraded from Windows XP, could this have something to do with it?
