Guild Wars 2

Hello I do not know if this is in the right subsection but I think it relates more to the Black Lion Trading Co. than anything else.

Last week I was using the site gw2db.com to keep track of item’s demand and supply- If I searched for an item, there was the average monthly price etc. but also a link to 2 graphs – I think I had to click “Show more” to be taken to this page…

This page had a graph showing ~how much of this item sold daily- now I wonder what happened to this?

I cannot find this graph anymore on gw2db and I wodner if it ist hte fault of my computer or there wa some kind of update that removed this?

And secondly, anyone know where I can find another site with such graphs?

Thanks

The gw2db site is part of Guildwars2guru I think, not linked to ArenaNet in any way.

I did notice the same change. Perhaps ArenaNet asked them to stop scanning the TP or banned them for “botting”?

gw2spidy.com provides detailed info too.

ye but gwspidy doesnt really give the sales/day

and I don’t think the wre doign anythign wrong afterall they were just doing what anyone could do with a 24h span of playtime

I don’t see how gw2db could determine the number of sales/purchases of an item. That site grabs its data from gw2spidy, which in turn grabs the same data from the TP that you can see. The thing that spidy adds is that it keeps a record of the data, allowing us to compare yesterday’s prices to today’s.

But none of the data includes the actual purchases. All they can track is how many WTS and WTB offers there are (in spidy terms: amount offered for sale, amount offered to buy). When those numbers change, it could be because of purchases or because people removed WTS offers and vendored/salvaged/donated instead and/or because people removed WTB offers to spend the coin on something else.

Spidy continues to show the same data they’ve always shown (plus additional information for crafting, as appropriate and when gw2db has the necessary recipes).

They indeed keep track of the sell offers which give accurate results for high end weapons because cancelling these results in a great amount of money

A reasonable assumption can be made that the amount of buy and sell listings goes down that they are completed sales but this is not 100% true. Some listings were just canceled and there is no way to know how many are. So in general this is not a good measure of actual sales. There isn’t really a best way to see that except with how fast the lowest sell listings move. Really easy to see with crafting materials like wood and ore as they sell in really high volumes. But with rare items that there aren’t tons listed if those who listed stuff really high priced compared to listings made since doesn’t sell their item after they feel they have waited long enough they may very likely take the hit with the listing fee and remove and list again. Also if the same number of items sold as were listed the number of listings wouldn’t change. So it would look like none sold even though they did. And is more likely to happen than people removing listings

@Jia

Looking at the lowest listing only should be enough – why would you relist if you are consistently the lowest seller? undercut yourself and lose a potential 10g listing fee?

secondly, gnoring any sale listing after that works just as fine – those cannot be sold without the first one being sold so only accounting for the lowest listing is I would say 80% accurate which is all you really need over a long period of time for rare items.

Point being any other sites that provide this kind of information?

The point is that spidy doesn’t track transactions; it tracks offers. Yes, you can make certain evaluations of the likely number of buy and sells based on looking at offer volatility, but that’s an extrapolation — it’s not true data. And yes, those theories will be more accurate for high-end sales, but there’s no way to evaluate how close to 100% (or how far) those numbers will be.

Any site purporting to give data on actual sales is making the numbers up, because there is no way to verify that data.

Instead, it would be reasonable to report trends. For example, they could create a new term that measured the changes in the relative changes to the supply:demand ratio — typically, prices are going to drop as that ratio drops or spike as it goes up.

Spidy does this for people who can read their graphs, but doesn’t put it into a single number or icon: you can see if the supply is increasing or if prices are spiking without a change in the supply (often a sign of arbitrageurs buying up product to reset the market).

If you can only look at the lowest sale price then I can’t think of a reason why someone would remove their listing. So in that case then it would more than likely be the item sold if the amount of listings for the lowest price went down. I just didn’t think this information was able to be tracked. I know the total amount of listings can. There is a level of assessment that has to go on if you are trying to decide what to sell an item for if it isn’t to the highest buy or at the lowest sell. Knowing how many sell over a period of time might help.
