How does Steam Marketplace determine which items get listed first?
I've been using the steam marketplace to sell cards for a while, and I've noticed something unusual about how ordering is determined on the steam marketplace. Obviously, the lowest price item ends up on top, but after that, I have no idea how steam determines how items get placed on the marketplace.

Logic would dictate that the first ones put up are the farthest at the top, as they've been waiting the longest. This is true 90% of the time, but occasionally someone will post an item at the same price as me and get their item put up first on the marketplace. I've tried seeing if this is a glitch in how steam rounds up cents when you put extra decimals into the cent value, but that didn't seem to replicate the effect. I thought it might be based on steam name, but my steam name is near the beginning of the alphabet and people that have appeared before me have had names both before and after me in alphabetical order.

Even more bizarre is the fact that I've posted 2 copies of an item on the marketplace before and have managed to have people get items placed BETWEEN my sold items. Obviously, this is a bit bizarre as it seems to indicate that the placement of same priced items is sometimes very random.

Can anyone help me on this issue? I'm tired of getting price sniped by people posting the same prices as me.

It's easy. First its the price as you already said. Lowest price = first place. After that its the time where they have put in.
That some person got their things between yours is just "luck", they put it in the same time you did. Some person, like me, put stuff in market 2-3times, just to be on the first page & selling it faster.
You need to remember that there are a few million people using steam at the same time. It's more than likely that there are a few ppl putting stuff in the market at the same time.

It's normally all about the price tag. Want to sell fast? Set your price .01 under your competition.

Yeah. I actually found the answer to this, already. It's not an issue of "timing" and "millions of items" being placed (because I normally work with items there's like 100 of). It's actually that people with lower value currencies have an inherent advantage on the marketplace. Someone living in Russia can drop the price by one Ruble (which is less than a cent) and get preferential treatment on the listings while still getting the full price for the sale (it ends up rounding up the fraction of a cent in their favor, apparently).

The point is. I've had items up for days at one price and had several people appear before me that were listed afterwards for the exact same price.

It's apparently a problem that several people have complained about because it means that some people have to strongly undercut the average market price to have a CHANCE at selling an item (since some people can just insert theirs at effectively the same cost ahead of you). Apparently, Valve's not really gonna bother doing anything about it though as they've never even commented on this problem.

As for the item appearing inbetween listings I'd had up for days, that's apparently just a market glitch.

...And this doesn't always work when you're working with an item that's selling for only a few cents to begin with. You actually cant' even sell crates for TF2 for 1 cent since you'll NEVER reach the front of the queue. Either way, REQUIRING people to undercut prices while others don't actually have to is still a reasonably unfair market problem.

In other countries the list still makes sense.

Did you ever think about that its maybe even you who gets ahead of someone?
And you can bet that everyone gets just what he set an item up for.

That sentence doesn't make a lot of sense, but I THINK I got the gist of that.

If I'm understanding you correctly though, even if we're arguing that the listing makes sense in other countries, the person that pays for the price in USD still has to pay the full price (which the extra fraction of a cent apparently goes to the seller in this case). If someone is paying an equivalent cost, the market should still be showing the listing in the order they were put up in, with the cost translated for the account (the system already does the calculations for currency conversation, adding the sort by date AFTER the conversion wouldn't actually be terribly difficult). The fact that it's nearly impossible for some people to even basically give away items over the marketplace is almost patently ridiculous, though.

The situation is apparently even worse for people whose accounts measure currency in the British pound too, since that currency's lowest denomination is STILL worth more than anyone else's single cent.

Honestly, I've heard plenty of arguments that steam marketplace items should just get listed by date for simplicity, and I'm starting to agree with it. The way the market is currently setup causes costs on items to rapidly crash as is, and that's pretty much bad for everyone involved EXCEPT the buyer (who doesn't actually have to search for lower prices).

How would you solve it?
The "extra" money gets eaten by steam.
It just happens that there are currencies with more "steps" in comparison to just 1 cent steps as you have them.

For example the former italian money lira... it had 1000 steps, while the lowest steps in another country were 100.

Like I said, above. The two obvious fixes are either to:
1. Sort the currency when you translate it into local currency instead of sorting it before translating it. Which would be that for some looking at a posting of 3 cents, the earliest posting that translates to that shows up. It still gives people with currencies with more steps the ability to undercut in their own country, but it removes the part where someone with a currency with less steps can NEVER show at the top of a popular listing on any country.

So, as an example, if something gets listed for 1 British pound, and someone from another country undercuts them by one step in their own local currency, they'd still be listed AFTER the earlier posting since the person paying in a British pound would be paying the same amount.

or...

2. Simply remove the sorting by cost on the steam marketplace. The 100% transparency of all market statistics has actually caused most items to lose large amounts of value over time which is really only beneficial to buyers. Even if you sold less often and slower with a "first in, first out" listing system, you'd inherently be making more on each sale. Hell, this would even encourage the TRADING part of card trading instead of people just selling their expensive cards and buying cheaper ones (which, having been in the Beta, steam wanted trading cards to be something that stimulated the community, not just something that earns them a few extra thousand bucks a day). Mind you, this does mean that people would be paying more overall for items on the marketplace, but there's even a weird economic statistic that shows that people tend to see more value in something when it's not listed at a microscopically small cost (eg. People actually view products that are free as being higher quality than ones sold for a dime even if the dime one is actually a slightly better product).

The price should be ordered by the effective price for the actual user. That makes sense.


About your theory that prices decrease because of this, its not. Prices fall that fast because for a kid it means a lot to get pennies, and they want it now. 1000 kids can bring a value down to like nothing very fast.

Except that people are forced to undercut the price because that's visible. If someone lists it for really low near the back of the list, they'll still likely sell it quickly to someone looking for a good price, but it won't force everyone that posted before them to continue to undercut the item. In other words, how many people will search for the price that undercuts the good one on the first page by a penny and how many will just decide the extra cent isn't worth their time?

It's the continual undercutting and bid wars from 3-4 people trying to get the quickest sell from market transparency that causes items to consistently lose value.

Removing sort by price wouldn't solve anything. I could list 30 items at $5 for an item that sells at $1 and as the $1 priced items sell my $5 items remain. Now in order for someone to find a $1 version of the item for sale they have to scroll through several pages of people trying to shark before they get to any sale that is meaningful. There are a lot of traders on steam that post $1 items for sale for several hundred dollars. Your system wouldn't help anyone in the long run making sales less likely in general as people decide using the steam market is too much work.

Your original idea of having steam sort by time posted after doing currency conversion would be a simple and effective solution to the problem of same value undercutting. It's certainly something that the good people at valve should have thought about when they made the system. At the moment it heavily favors foreign currencies.

You need to learn who to contact if theres a problem. And where to write about it.
In this case, paysafecard. Because the steam process didnt happen.
