Do you think a card you have is in very high demand?   How about a statistic added to the site to confirm or deny that?

I got an idea from beagleshortstop when he mentioned he looks at this manually during a trade.  I don't know about the name but it could called something like hot percentage, want/trade percentage, or demand percentage.   The stat represents the percentage between the number of times the card is on a wantlist vs the number of times it is on a tradelist.  Basically if 10 members each wants one card and there are a total of 10 cards for trade/sale then the number would be 0. In that case the supply and demand even out.  I was not a math major but here is the formula I am using.

((N2-N1)/N1)*100 = PH      N2 is the higher number and N1 is the lower number. It would end up being a percentage with either a + or - in front of it to indicate which is the higher number.

A couple examples would be:

1965 topps #110 Ron Santo   -   want  88   and for sale/trade 8   result would be +1000  formula ((88-8)/8)*100=1000%

1990 fleer #3 Jose Canseco  -    want  12   and sale/trade 296   result would be  -2367  formula ((296-12)/12)*100=2366.67%

This stat could also lead to hot and cold card lists (cards that are trending up and down the most).

Do you think this would be something that you would use if it was available?

Got a better name?

Any other stats that think would be nice to be added?

Exactly what I've been trying to figure out for my FS/FT cards.  I think it's more valuable than price for determining trade values.  
 

if I want a $3 card that 500 people has FS/FT and someone proposes a trade for a card of equal value but 40 people want it and there's only 1-2 available on the site, I think we'd all agree that's not a trade we're jumping to make.

But like beagleshortsop, I wish there was a way to tag those cards off the bat so I don't have to look at the comments for every card that fits that description.

The only workaround I know of right now is to go to the "Most wanted cards" list and scroll until I see my cards.

Very intriguing idea. What if we didn't use a percentage (and thus not multiply by 100) and use the following formula?:

N1/N2 = Rating Number

Then in your above first example, the '65 Santo card would have a rating of 10 (88/8) and that would also mean that 10 times more people want the card than have it for sale/trade.

In the second example, the Canseco card would have a rating of -24.67, which in this case means that almost 25 times more people have the card for sale/trade than want the card. (There would have to be a condition that if the For Sale/Trade number is higher than the Want number, than make the result a negative number.) As you might see with the both formulas, programming them into the software may not be that simple but it's probably doable.

One little problem might crop up if the lower number (N1) is zero or if both numbers are zero. I would think if that is the case, the result could simply be "None for sale/trade" or "None wanted". Or maybe there could be a minimum number for N1 and N2 to qualify for a rating.

Anyways, I would definitely be interested in seeing those stats and hot/cold lists for each sport.

Here's some potential names for this stat in no particular order:

Popularity Quotient (PQ)

Card Popularity Rating (CPR)

Popularity Grade (PG)

Demand/Availability Number Grade (DANG)

Demand/Availability Rating Number (DARN)

Demand/Availability Number (DAN)

Card Rating of Availability/Demand (CRAD)

Rating of Availability/Demand (RAD)

Availability/Want Score (AWS)

Cold/Hot Popularity Score (CHPS)

Hot And Cold Score (HACS)

Want And Sale/Trade Score (WASTS)

Want/Availability Quotient (WAQ)

Want/Availability Score (WAS)

Want/Availability Rating (WAR)

I could see this stat becoming about as popular as PSA grades.

Really like the idea. I'd like to present a more simple calculation for "Availability Over Demand".
A simple subtraction of integers. No problems with dividing by zero.

SIMPLE CALCULATION

Display ALL the numbers used in the calculation.

ONE ISSUE: What members are used to calculate Wanted and FS/FT
Calculating N1 and N2 from ALL Members will create an inaccurate presentation of the data regardless of what the formula is. The chart above shows that eight 1965 Ron Santo cards are available. What good are these numbers if six of those cards are on FS/FT lists of members that haven't logged on to the site for over two years.

Using data from only ACTIVE members presents a more accurate presentation of data.

That's my two cents.
Let me know what you think.

By active, let's say that a member has to have logged in within a month of the current date to have their wants/collection to the pool.

I'd have to agree that simple is better on this one. I'd want to know more that 80 people have a certain card (And having a link that goes to each of the user's names that have the card would be handy) that I want and that only 20 are in the market for it, than what say there was an excess of 300% from people having the card to people wanting it. 

Just another small thing, for pricing of cards, using the website/book that is quite literally the go-to for the card prices for a certain type of card right now versus an ebay sold link may be better. I keep getting rejected for pricing for "Gaming" cards when I go from the book (Technically an even updating online source) versus an ebay sold link. A bit annoying if you ask me. I know that this has literally nothing to do with what is up above, but it was stated "What other features/things would you want to see in place." So, I think this fits.

I do think this is interesting, but I wouldn't want people to think this should up the value of a particular card.  Just because there might be a few for trade/sell here doesn't mean you can't find the card elsewhere.  I receive a lot of trades and people value cards differently.  I have had people ask for hundreds of dollars "Ebay sold prices" and want to give me peanuts.  

I would rather see a option that gives you active users with the most wants and or matches.  Maybe this is out there and I haven't seen yet.   

Trade On!

Some good replies already.

I like many of the name options.

I am big fan of simple which makes it easier to code, uses less computing power, and makes it easier for people to understand.  I think both suggestions above simplify.  The reason the percentage was included in the original calculation was to differentiate between  300 to 298 vs.  3 to 1 which I believe in the example below which each be 2 over.   So I guess the question now is should they both just be 2 or does it make it difference that in the second set of numbers, one has 3 times more for sale than wanted?   I am not sure where I stand on that one but explaining why I chose the complexity on the original design.

Godzilla8you,  If I understand what you are looking for correctly,  take a look at trade matching.

I think this is a great idea!  It would certainly help me determine which cards to upload first when inputting traders (no hurry to get my '88 Donruss doubles listed).  Just out of curiosity, how many active members are on this sight?

That sounds like a possible use case.  Interesting that due to the nature of this stat, your act of cherry picking the "hot" cards to input as for sale/trade first would actually make them more "cold".

I thought I ran into the total amount of users somewhere on here one time but can't recall how to get that page again.

interesting idea, but I'm not sure how accurate it is, how good of a tool it is,  to predict "value."

I've got a couple baseball player PC's which I am going for Topps flagship + all inserts.  Mostly avoiding base in other brands.

When I check trade match notices, for my trade bait, I go to the traders list of cards for trade, and search on my players, scanning for cards that are easily recognizable as inserts. 

I then check the card statistics of  in collections / on want lists / on trade lists.

very frequently I find that there are just a couple in collections, a couple of want lists, and only 1 on a trade list, the one I am looking at.

What does this tell me?

  I think it says that the majority of collectors / members on TCDb just collect base. or perhaps Everything Topps flagship. 

but a rare insert / parallel from Panini has little demand here.  the marketplace for a rare Panini card insert / parallel is COMC and ebay.
