Sales at 20, 22, 22, 22, 23, 25, 25, 27, 30, 33, and supportive sales for ~22 and ~30. Gonna exclude 20 and 33 and too high and too low, and go with 22-30 since those points are common enough and the mid-value would be near the common trading point at 25 too.

Sellers at ~30 keys and buyers at ~18 keys.
