15k matches, but snapshot suggests ~17k, which is what buy orders were at the time, so 17?

bulk quicksell

tricky one, but as buyer's have since dropped to ~13k https://gladiator.tf/listings/61e7c6a6378b2311158a2930, I'm inclined to think the market has trended downwards, as likely sales indicate: 17 -> 14 -> 15, 17 -> quicksell (implies lower value)

former unsold at 19 has since relisted at 18, 25 unsold for a year.

Given STN.tf's existing ~15k buy order, 15 flat seems appropriate here.
