I could see this being ~31 keys from seller's side but unclear, likely a buy order

Classies: https://gyazo.com/bd85ad714122fa6b3dde2e7787a648a6

Buyers at 32 keys, unsolds at 52-55.

Some sales below 39 are potentially being excluded, which would nicely balance out with sales above unsolds. Going with 39 - 50 keys for now.
