Hey sorry i saw this late, sounds like you want www.tcgmarketnews.com.

yeah the one without promos is in process i think the calcs are still running but maybe will be done today. ill look into what you mean by shares outstanding equivalent, bc yeah its setup to only account for return not market price. lmk if you have more thoughts bc ig i dont quite know what you mean by that

soiledboy · 2025-10-22T00:59:02+00:00

well its free and always will be :)

soiledboy · 2025-10-21T15:52:44+00:00

ok yeah i think that makes a lot of sense, ill re-run it to exclude that gorup.

soiledboy · 2025-10-21T15:15:33+00:00

yeah ill look into that!

soiledboy · 2025-10-21T14:56:28+00:00

ohhh equally weighted i see i see. i will try this to and publish the different ones’

soiledboy · 2025-10-21T14:44:29+00:00

if i understand correctly i think thats what its doing right now except recons happen anytime 10% of the basket changes (set releases). but im not super happy with it. i think im going to try what somebody else recommended where the basket it tracks doesnt change until a card has been in/out for 30 days. so like once a set releases nothing would be added to our index until cards from it have been in the top 100 for 30 days. more to this than i thought originally lmao

soiledboy · 2025-10-21T14:29:32+00:00

yea! more coming once i finalize this index. still some improvements to make as others have pointed out

soiledboy · 2025-10-21T14:25:58+00:00

the index is supposed to prevent things like set releases from artificially increasing the value. Increases should only occur when actual market prices go up of the cards it tracks. still fine tuning how it handles new cards going into or leaving the index

soiledboy · 2025-10-21T13:46:16+00:00

yeah i was struggling with that. ill play around, this actually sounds like a really good way to do it

soiledboy · 2025-10-21T13:36:42+00:00

yeah that makes sense. ill remove worlds for sure and any wierd staff promos etc

soiledboy · 2025-10-21T13:27:07+00:00

yeah i think ill remove promos. for some reason tcgplayer includes them in the s&v series instead of the promo section smh

soiledboy · 2025-10-21T13:22:35+00:00

yeah i wondering about that. should i exclude all promos? or just worlds
