Dear, People of the interwebs using the auction tracker auction.goonquest.com

[Ravhin]

Hey,

First - thanks! Use this thing everytime I'm in EC. A few suggestions:

1) Although the plots are beautiful, have you considered something a bit... nicer? (e.g. http://pchart.sourceforge.net/screenshots.php?ID=2)

2) Things are a bit messy with duplicates, fake things, badly parsed things, etc. Either (a) a master list of items with aliases that get mapped to the item, or (b) a way to link two separate names so that they are known to be the same thing (i.e. "aon" and "amulet of necropotence").

3) Market trends above just item by item. For example, the top 20 most traded things and their price trends with time. Volume/number of trades with time. Some measure of inflation / plat in the economy with time.

4) Few parses things which are handled badly now:

"bracers x2" -> "bracers x" (with some weird price I suspect)
"reed belt - zaharn's coronet - diamond - brigine tunic" (dash as an item separator)
abreviation grouping (i.e. "plat"->"platinum", "rubi"->"rubicite")
"selling" as a WTS tag

thats all for now

Maybe just use the median instead of the mean. That will prevent 99999pp spammers from influencing prices. If you're able to present the mean, stdev, median, mode, and quartiles it will be tougher to be deceived by outliers.

Excellent tool, I use this thing all the time as my price check before I sell or buy things. Of course it's not always 100% accurate, but it's super-useful and I really appreciate it!

1) pchart would be fantastic but im not using php if you find something similar in ruby or javascript .. i prefer javascript theres no need to do this on the server

2) i don't have the time to sit down and make a list of abbreviations to items if someone wants to start doing this ill be glad to add it in. if someone can find a link to the item database that p99 uses from eqemu so i can get a list of items names that would be neato too to check to see if its actually an item when i run the parse

3) Ill try to make something simple but calculating trends can be tricky if the data doesn't get updated enough it will most likely be misleading you can't really calculate the volume because you don't know if a sale actually happened this just reads the auction channel spam from your log file

4) yea i know its because the current parser is "good enough" i need a better set of test data to test against im retaining all logs uploaded for the next few days so i can try and build a solid set of test data maybe implement a baysien learning system

Interesting to me, at least, are the number of times in a row the same price is found - like 'a broom' - you can almost imagine some guy with his PST auction hotkey hitting it every so often until it sells.

Not that the length of the repeated string indicates the utility of the item at that price or anything, but socially interesting to me nonetheless.

Think i may plug in http://code.google.com/apis/visualiz...dtimeline.html
later its the same thing google uses for stocks

Yea i donno how to avoid that without having to map every auction to a user and then doing a look up each time a item is parsed ... i think my poor web server would die i do some tickery with hashes to detect based on timestamp if that auction has already been recorded

remove doesn't actually remove it just hides so i can restore any item
