Sales at 27, 27, 27, 29, 29, 30, 31, 32, 32, 33, 33, 34, 34, 36, 36, 36, 36

27-29 looks low with all those buyers at 30, will keep 30 as the low end to account for the lower sales/buy order dumps

36 is a really common trading point and they're the most recent sales.

Taking 30-36 keys here, if the 39 sale was traceable it would most likely end up being an outlier too with the unsold at 37 and lower sales
