New Auction House Formulas

I think i have figured out the new auction house formulas, and while they may be easier on folks selling low-value items, they are harder on folks setting up auctions longer than 4 hours. I'm not sure what the best way to wikify this would be, and please correct me if i'm wrong, but it seems to work like this:

The per-unit LISTING FEE is determined as the HIGHEST of the following three values:

0.5% of the Buyout Price

(OR)

A percentage of the Minimum Initial Bid (determined by Auction Time):

Auction Time
4h: 10% of Minimum Initial Bid
12h: 12% of Minimum Initial Bid
24h: 15% of Minimum Initial Bid
48h: 20% of Minimum Initial Bid

(OR)

A percentage (determined by Auction Time) of a Minimum Per-Unit Value (determined by Star Quality):

Auction Time
4h: 10% of Minimum Per-Unit Value
12h: 12% of Minimum Per-Unit Value
24h: 15% of Minimum Per-Unit Value
48h: 20% of Minimum Per-Unit Value

Minimum Per-Unit Value by Star Quality
0*: 100
1*: 250
2*: 500
3*: 1000
4*: 2000
5*: 5000

This creates a matrix that looks like:

AT | 4h | 12h | 24h | 48h
0* |010 | 012 | 015 | 020
1* |025 | 031 | 038 | 050
2* |050 | 060 | 075 | 100
3* |100 | 121 | 150 | 200
4* |200 | 241 | 300 | 400
5* |500 | 600 | 750 | 1000

The LISTING FEE is returned for successful auctions and an AUCTION FEE of 10% of the final sale price is assessed.

I don't need to worry about

I don't need to worry about listing fees as long as they are refunded for a sale. My ridiculously high priced auctions always end with a buy-now, no matter how many times I mark up the prices, bwahahaha!

But thanks for showing us the new formulas.

If i get it, the change is

If i get it, the change is only one: auction duration gives no more a fixed fee value but works as a multiplicative factor for each of the other 3 parameters (it applies to the 0.5% of Buyout price too, I checked)

so now fees are cheaper for low star items (as long as you keep initial price low), but more expensive for all the rest unless you make 4-hours-only auctions.

Thanks for the correction.

Thanks for the correction. I've edited the wiki page, hopefully in a way that is easy to understand. Unfortunately, this just seems to tip the risk vs. reward calculation of auctions further against those trying to sell high-value items; unless its something that is guaranteed to sell, or something that you're willing to take less profit on in order to sell it quick, it is becoming less and less attractive to post these items on the auction house.

well done

1) @alhazred23: Well done on reverse engineering this.

2) Doh, I have been hitting foul balls this whole week. It was not my intention to make the listing fee higher than the sale fee. I never want to incentivize using an alt.

3) So, let's fix it.

How should we calculate the listing fee? What about if we did it exactly how it is now, but the duration multiplier is cut in half? (That way a 4-hour is only 5% of the initial bid and 2-day is 10% of the initial bid.)

Are there other changes you'd like to see? Is the star value too high?

Let's try to keep the suggestions realistic. You know what the idea is, let's just fix parts of the formula that might be imbalanced.

Well, if anything, you could consider a "Cancel Auction" option. I'm not sure if it's better to just have the ability to not refund the listing price, or just refund the listing price then charge a certain fee for "Cancel Auction", but it should be there.

People are effectively doing that anyway by having people they know (or an alt, don't remember) buy the item back, and just get charged the 10% completed auction fee. Nonetheless, cancelling would still have a cost, so mass-random-auctions would still be discouraged.

How should we calculate the listing fee?
The listing fee should be zero. Seriously.

Before you HWFO, step back and think about things.

* This is not a real-life auction, where the auction house has to store physical things and a listing fee is needed to keep it form turning into a free warehouse.

*this is not ebay where every auction is some unique thing that needs to be looked at by buyers. One red shard is as good as the next.

* the cr<->CE exchange works very well (as does the YPP PoE<->dub exchange) and it doesn't have a listing fee.

There simply isn't any good reason for having a listing fee. It primarily hurts new players who have no clue the price of drift wood vs red wood vs ironwood. As much as it is human nature to think that our favorite part of the game is the most important, the AH is never going to be the center of the game. You will never see advertisements about who fantastic the AH, people aren't going to say to their friends "you should play spiral knights, it has a great ebay simulator!".

Listing stuff should be as painless as possible for the vast majority of players who are only ever going to want to sell the materials that they haul up from the clockworks. They do not need to have to worry about actually losing 10 times as much on listing fees as the material actually is worth.

Sure, someone will go and list 100 auctions for 1 red shard at 1000cr. So what? With the sort options, most people will never see those auctions, just like people don't see the crazy offers on the cr<->CE exchange, That person will have spent a lot of time creating all those auctions, even as a prank, it will get old very very quickly. Their time is their listing fee. Oh, and the seller is also out of the use of those materials, that is another small cost, but that is really all that is needed.

Just rip the listing fee out of the game. It is a needless complication that just makes the game less fun.

I somewhat agree with wrs1864

I somewhat agree with wrs1864 here, but simply because of how easy you guys made searching items and ordering them on the Auction House (thanks a lot for that, by the way!) - A listing fee isn't really all that needed. Spam auctions would be made, but they could be easily ignored. People will make spam auctions no matter what, anyway.

However, it's generally better to keep the listing fee - Having none at all could be pretty chaotic, I guess. The current formula is pretty good, except for the duration thing. It'd probably be better if it didn't go over 5% ~ 7% of the minimal bid. So I'd say using the same formula, but reducing the increase on duration to 1/4 the current value would work. If you really don't think it shouldn't go this low, then I guess simply cutting it in half would work fine.

I actually don't mind listing

I actually don't mind listing fees but the latest update is absurd. If you don't want to ever have listing fees be more than final value fee, then just take what's currently in place now and cut it in half. (i.e. @ 48 hrs it is 10%, 7.5% for 24 hrs, 6% for 12hr, 5% for 4 hr) I think this is pretty fair for everyone involved, still prevents junk auctions since 48hrs is 10%

Why?

There are only so much time for new players to learn the game. Which is more important, learning the difference between the various lumbers, or learning the differences in prices between driftwood/redwood/ironwood? A new player is going to want to sell everything they can to get crowns, it is real important that they don't get bitten by some irrelevant "feature".

What compelling reason is there for keeping a listing fee? How does it make the game funner for the *average* player? (And, the average player probably hasn't made it to the bottom of T1. The average forum poster is *NOT* an average player.)

Personally, I have no problems with a listing fee either, there have been very few times that I've paid it. But, indifference is not a compelling reason.

Suggestions (if removing the Listing Fee isn't an option):

-Retain stepped 'auction duration multiplier' on the Listing Fee but reduce the 'base' percentage by at least half (To Be Implemented, yay!)
-Refund 50% of the Listing Fee on failed auctions (encourages people to sell things)
-Add a Cancel Auction option, where the Seller can force the auction to 'fail,' and lose half of their listing fee; if you need strings attached to this, make it so that the auction cannot be cancelled in the last X hours, or the auction cannot be cancelled if the Current Bid is equal X percent of the Buyout Price.
-Reduce the Star Quality minimum values by about 25-50% (the great majority of materials just won't sell for the current minimum values)

1% listing fee if you have no items currently on auction
2% listing fee if you have one item currently on auction
3% listing fee if you have two items currently on auction
4% listing fee if you have three items currently on auction

I'm assuming you lot are more intelligent that your recent design decisions indicate and can follow the arithmetic progression going on there. You get perfectly acceptable listing fees and a process that limits the number of auctions a character would want to list.

Or, you know, you could just drop listing fees altogether.

Oh come on.. that's a little unfair. wtfwtf already said that having the listing fees hit 20% was a mistake. His communication with us regarding auction house features and development has been great. (i.e. crushing our dreams of uv display/sorting instead of shutting us out completely) There is really no need to get aggressive like that. We asked for reduced listing fees and outside of this small time frame where they went up we're going to get that.

I don't see why some people

I don't see why some people are up in arms about listing fees even after the 50% cost reduction. All of my hundred auctions have sold at profitable to extremely profitable (500% markup), and I never list anything at too low a price to keep from contributing to market saturation. I also don't imagine why any new players would be dumb enough to be confused by a listing fee, so it's a non-issue.

The only folks who would really have an issue with listing fees are those who don't sell their items. If you're getting a lot of your items returned, you're doing it wrong. Perhaps you shouldn't be charging 300k for that medium UV sleep resist wolver coat? You won't hit the jackpot, silly. You deserve to pay a dramatic listing fee and eat that cost when the item is returned to you. Learn from it.

On another note, it wasn't mentioned in the patch notes specifically, but I'm really happy the bid increments have changed to be a percentage of the current bid. Now auctions at 8000 crowns aren't incremented at 10 crowns each still, and make bidding wars a bit more interesting and possible.

I was directed here after

I was directed here after stating that I use alts to as a loop hole to the current auction system. Obviously, the current system is broken and cutting it in half would not fix the issue either. The reason is for 4 star and 5 star materials. These do not sell for a lot yet their auction listings are 400 and 1000 for 2 days postings. Now, cutting it in half would make them 200 and 500.

But let's see:

Miracloth sells for about 1000CR (or less)
Posting fee is 200.

Sorry but I would still rather buyout my own auction than losing 200CR because 10% of 1000 is only 100. This is worse for 5 star items that do not sell very well.

So the simple solution should be listing price should be:

4h - 4% of bid or buy out price (whichever is higher)
12h - 6%
24h - 8%
48h - 10%

The cap is 10% as this is the fee for buying out an item. Any listing fees higher than 10% would cause the seller to prefer buying out the auction himself.

Which leads to another flaw in the system...

NOT BEING ABLE TO CANCEL AUCTIONS WITH BIDS

I can see the reasoning but people can still buy out their own auctions so there is no reason to not allow this. If I list my item with a 10CR starting bid and a 2000CR buy out, I should be allowed to cancel my auction if I do not like the current bid because I would rather lose the 10% auction fee and lose over 10% of my item's value.

But you ask, what if the item did not have a buy out?
The answer is: Keep the bid price the same because people will simply also bid their item out to prevent any penalties for canceling auctions. Let me repeat, other than losing initial listing, DO NOT PENALIZE for canceling auction otherwise people will find ways around it. This is promote bid wars which are GOOD for an Auction House. If the item sells, well, you guys get a 10% cut anyways!

Star values...

There are zero and one star mats that sell for 5 crowns each.
There are 2 and 3 star mats that sell for 100 crowns each, maybe less.
There are 4 and 5 star mats that sell for 150-200 crowns.

I have no idea what the star fees are based on, but for a substantial fraction of each star level they are way to high.

Many materials dropped precipitously in value with the latest update too, and we can quickly see that the reason materials went for -more- in the AH than they had been on /2 before the AH is simply that the AH sort put 'groups' of materials away from singles and made selling batches hard. Now that people can sell batches and they are sorted in prices are going back down to and even below their 'old' prices before AH.

It's really all supply and demand... it's worthwhile to more people to sell batches of 10 of something than it was to auction 1 at a time of something. Rarer materials never had this problem and naturally went down (mostly) from pre-AH prices.

I wonder if there might not be a rebound in the market when 'old' players finally empty out their backlog of extra materials, but I don't think it will be a substantial rebound if at all. Any rebound effect may well be countered by more and more players getting used to using the AH.

The upshot of which is to please make the star minimum auction listing much lower. It's painful to pay 100 per shard because they're now going to sell at 30 instead of 80 or 40 instead of 140. Though there's still hope for my start bids to be clicked even if the BIN is now looking absurd. As of this morning anyway, maybe there's been a rebound while I was out for the day, but I doubt it for the market force reasons I mention above; I think we're moving to the natural price. Also lowering the star listing fee will in turn drop the price of materials further - less risk means more people willing to try.

Honestly I'm not sure 0 and 1* mats need a minimum.

Also, the minimum really shouldn't be star based -anyway-, there's huge variance in a star level, and of course recipes and equipment should have a different minimum from materials anyway. Ideally, the minimum would be something like half of the listing fee for the average auction on that item that completed in the last 72 hours... but that kind of moving average statistics gathering is not a quick job!

The only reason for the minimum listing fee, after all, is to discourage people from simply putting up rather annoying auctions that start at '1' for a 10k item, making bidders do annoying work in order to reduce the seller's risk to near nothing. As such, the minimum really shouldn't be the listing fee anywhere -near- a majority of the time, but in the materials market it is. (In recipes and equipment, not so much.)

Yes, but with the sort options and filtering, chances are that most bidders won't even see these "annoying" auctions. The cr<->CE market is constructed well enough that it is impossible for crazy bids to be seen by anyone other than the person who placed them. I think that is the right solution to the problem of "annoying auctions".

As such, the minimum really shouldn't be the listing fee anywhere -near- a majority of the time, but in the materials market it is. (In recipes and equipment, not so much.)

While the listing fee for recipes isn't that close to the sell price, it is close to the profit you can expect. If the recipe doesn't sell, you have usually lost your only chance to break even on it.

So far, the strongest argument in favor of having a listing fee is basically "people deserved to be punished for making a mistake", but since it only hurts the seller, I don't see a need to punish them.

If ripping out the code to support a listing fee is too much work/too risky for a quick fix, just have a fixed listing fee of 5cr. Even for mats that don't sell for that much, a 5cr fee isn't really a problem even to new players.

I've already posted my

I've already posted my opinion on AH changes in the suggestions board, but since it's on page 9 and I know someone is active in this thread.

    It should be changed so that a 5% fee applies when the item is sold. For the listing fee, it should be 1% of the buyout price if one exists, otherwise it should be 1% of the starting bid. In either case the listing fee should never exceed 1000 crowns.

In hindsight, 1000 crown cap was probably too low, can bump that up to 5000. You can also add a minimum listing fee of 50 crowns as well. I also don't really see a problem of having a listing fee higher than the sale fee either, provided both fees aren't stupidly high.

If you want to take into account star rating:
0* = 1x multiplier
1* = 1.1x
2* = 1.2x
3* = 1.3x
4* = 1.4x
5* = 1.5x

If you want to take into account auction duration:
4h = 0.3x multiplier
12h = 1x
24h = 2x
48h = 4x

It's not rocket surgery, guys.

The listing fee is just a security deposit against dumbassery.

Doesn't need to be some absurd amount, just enough to not make it worth it to screw around.
And certainly not enough to make it worth buying your own items to save losing it.

I think that is the right solution to the problem of "annoying auctions".

If someone lists Divine Avenger Recipe or the Sun Silver needed to make it with a starting bid of '1', a -lot- of bidders are going to see it when they sort for lowest bid price looking for something affordable, or when they sort by 'end time' ... such an auction would go on being 1-up'd for hours and hours and float around in 'very short'. Once through that's fine, but if that sort of auction became habitual it would be very annoying. of course people could run them anyway just to guarantee bidding wars (and in fact they do), but we'll have -less- of them if the auction fee risk is the same up to a point.

(Bidders are actually less likely to see things that have very high starts, except when they get to 'very short'.)

I don't see how having a listing fee has any impact on this situation. Such an auction would quickly get bids and therefore make any listing fee irrelevant.

But, to address this off-topic comment, the bid increment has been raised to a much more reasonable 5%, so I don't think it would be *possible* to be "1-up'd for hours and hours". In practice, someone will usually jump the bidding up to something that is more reasonable, probably still "very cheap", but no longer "stupidly cheap".

Listing fees...

I don't see how having a listing fee has any impact on this situation. Such an auction would quickly get bids and therefore make any listing fee irrelevant.
If you pay a straight 10% listing fee (for example) you would put up (and risk) 1000 crowns to start your auction at 10,000 crowns. A conservative player might put their starting bid between 1 and 10 crowns to avoid risking that listing fee. If you have a minimum listing fee for a given item of 1000 crowns, then there is no reason not to start your bidding at 10,000 crowns if that is a price where it is extremely likely to sell.

In may be more relevant to more mid-ranged items where someone might start 20 identical auctions at the same time.

Or it may not matter. Although I have not yet seen anyone enter a bid - every bid I've seen has been either a minimum bid or buyout, even on very underpriced items. Maybe I'm just not in the right auctions. However, if 5% speeds things up enough that even starting from 1 wouldn't take too many bids to reach a high value... then maybe it -should- be a straight percentage (or at least straight 'greater of x% of starting bid or y% of BIN').

As there is no other effect on auctions that I can think of for having a non-percentage minimum listing fee other than that slight incentive to have a higher starting bid. If very low starting bids don't matter, then lets just not have a minimum listing fee.

Actually there is one other aspect - minimum listing fees do make it more difficult to dump your whole inventory into the auction house simultaneously as you end up with a lot of funds being held in listing fees no matter how low your starting bid. However, that's only really a barrier to players who have inventories too small to be market destabilizing anyway, and I can't imagine that was the reason for the star-based minimum listing fee.

Or maybe there is something else it affects that I'm not thinking of.

Anyway, the latest adjustment to listing fees makes them not horribly painful in any case, although it is still occasionally possible to have listing fees higher than the value of the item... it's a lot rarer now, and it's not many times the value of the item. I think listing fees could still be better done, but it's a good time to say 'good enough' and go to content on that issue, I think!
