Ah! This makes so much more sense. Should have thought of this. Thank you for the clarification.

internal means, u sold it to an internal guild member.
means:
guild 1: 11% has been sold internally to guild members, 89% via vendor to "outsiders"
guild 2 and 3: 100% have been sold to people, who bought at the guild trader, noone of the guild u are in bought it

for traders this value isnt that important, for the guild leaders it can be a value giving an idea of community backup and vendor-reachability and wether the gains were worth the costs of the trader.

Of course:
As you can see the 1st guild shows an intern value of 11.45% - whereas the other guilds are at 0%. The thing is while The 0% make sense the 11% don't. This is the guild with the most traffic there is - so my contributions for the past week (I was away for most of it) should not be in any percentage over 1% really...

Can you provide a screenshot please? Id say its the percentage of sales, which have been sold internal (by another guild member).

So I just downloaded this and got in an argument over what the intern statistic part means? I thought it was the percentage my sales had on allover sales this week in terms of gold volume. But other members told me that the sum I sold could not possibly make up the percentage listed since they sold a lot more this week and thus adding all of it together woiuld mean the percentage would be over 100%. Neither does it seem to be the amout of items? I'm very confused. We found no explanation on what is meant nor if the amout shown could be correct.

Thank you very much for the thoughtful and informative answer. I didn't mean to imply that I thought the author(s) left it out, out of accident or laziness. I did not know the performance impact of that filter.

The main goal of ATT has been beeing performance friendly, in coding and in functionality, since back in that time another addon started blocking chars from login after beeing overloaded with sales information and having to reset it over and over again, which mainly has been an issue for the powersellers and trade guild gm which were in a couple of bigger guilds which have a lot of sales, and sometimes even selling on alt accounts as well.

That's also why some functionalities have been left out, it didnt happen by accident. The deal range filter is a performance eater, as well as usually no affine trader would as example just put an average price from an addon automatically into the listing, also no affine trader would use 3 months old prices as reference for his actual prices. This is also why ATT came with a purchase list, for reseller as example, so you are better able to remember what you bought for which price. The author as well as the alpha and beta testers were all trade guild gm and officers of bigger guilds and affine traders, which had to deal performance issues and also were able to decide and overthink, which functionalities are usefull and which can be left out.

I know Arkadius is, despite the fact he quit on playing ESO, still working on this addon and on new functionalities and users whishes, so there is the chance there will come such options, but also keep in mind, that the missing deal range filter didn't happen by accident or lazyness.

That was nearly a deal-breaker for me. I still use this for EU because I can't use MM there & on NA, but *sorely* miss the deal filter. That functionality turned out to be surprisingly important once it was no longer there.

I haven't really looked at it closely, but is there a way to tell which sales are from the trader and which sales are from keeps held in Cyrodil? Just curious.

That's actually not how ATT or MM work. They scan the guilds that you are in, so they function quite well for you even if you're the only one using them. Only TTC (Tamriel Trade Center) requires many active users to make it function as it pulls from scans and search results conducted by its users. The limiting factor for both ATT and MM is how good your trade guilds are rather than how many people use the addon.

Edit: Response to the bolded portion

This addon is awesome. The only thing I miss from MM is the Deal Range filter. Thank you.

ATT is just great, no lag over time unlike MM, and 2 functions that makes it better imo :
- price from other quality of the same item listed in the tool tip
- being able to adjust the duration used to calculate the average price from 1 to 30 days at will, that's very handy for jewelry recently for exemple

I'm hoping for an update soon, the add-on does work just fine as is, but people are less likely to try and use an addon listed as "out of date" in the menu, and less users means less data to work with for prices.

Thanks again for that awesome tool !

per guild sales are included.

Jungs wie siehts aus, macht ihr ein Update für Summerset?
Oder, weil das Addon läuft ja eh weiter, wie kann man das an Summerset anpassen, is doch eh nur ne nummer zu ändern.

Thank you Hawkeye & Arkadius! I look forward to trying it out!
