Everything about past auction values is broken

Westheim · 10-30-2019, 07:53 AM

This card had straight 88's for its past auction values, weird enough, but not impossible to explain away.

I bought it for 200 PP.

This is not explainable (see below):

At this point, I would propose a change for PT 21. Do away with the broken averages that are broken in all sorts of ways. List the last 5 to 7 transactions for this card in that field. The savvy player can probably work out the average for himself. Because this is ridiculous.

Past auction values are broken, but this isn’t an example of that. The median of all sales and of the last week of sales was 88. You bought the card for 200. The new median of all sales and of the last week of sales is 89. The highest sale price is still 250. Where is the error in your screen shot?

What is broken is that when live cards change tiers, or a card is part of a new mission, the new market rate can be written off as fraudulent compared to the prior prices, so no new sales are ever included in the averages, which get permanently stuck at old, even illegally low prices.

Excluding suspected fraud is good (note: if it’s fraudulent enough to exclude it’s probably fraudulent enough to investigate the user for a warning or ban), but it should also check the last N (~20?) sales, including suspicious ones, to see if the recent suspiciously high prices are really just the new normal.

I don't see what is weird at all here. This seems like one of the few cases where it is actually working.

There are live diamonds that still show past 7 day averages of 1500 which is literally impossible. Mission cards I've watched sell for 100K that both fields never change from 8000.

All three values were 88, including the highest winning bid all time. This was also the only Shocker card on the market; it's as good as impossible that someone posted another one that sold for 250 in the 30 seconds between buying this and bringing up this page.

Thus, if the top bid all time was 88, the median now can't be 89. It's broken top to bottom.

I have also raged about the diamonds (and perfects) with broken values before. I would like for someone with access to the code to actually look at it for a change...

This feature is not working at all. Look at the silver Howie Pollet card's last 7 average of 278.
