Buyers up to 31.07.

Considering 2 sales at 32, and only one buyer at 31 (the rest at 24 or so), plus a B/O of 38 that was paid 38, taking 32 - 38.

F⏣amy's Part:

https://backpack.tf/profiles/76561198066452389#!/compare/1527811200/1527897600 45 keys

Seeing how close the low end is to buy orders I'd indclude that too. There are too many low sales to exclude so that as a data point is fine - With that I'd go 32-45 here.

Taking 32- 45 keys.
