215 pure

141 key sale was traded back, was a buy order and is just low

238 key sale was spelled and above 220k seller so its high https://imgur.com/a/EsStFAk

That leaves us with 160, 197, 161, 180, 190, 208 (or 250) and 215

Buyers are now at 180+ https://imgur.com/a/zMx44oq

Going to go with 190-200 (rounding 197 up) and calling 160, 161 and 180k sales low, and 215 + (possible 208) high due to spells + sellers
