https://gyazo.com/dc46ce41fdc2cfeb46fa4e06b956d91a - 3 Bot.tf sales at the same price = 1 sale at (11) Keys

Sales we have are:

6.5, 8, 9.5, 9.5, 9.5, 9.5, 10, 10, 10, 10, 11, 11, 11, 12, 13, 13 and 16

Calling 6.5 and 8 low due to buyers and were likely through Mp.tf buy orders

Calling 13 and 16 high due to unsolds

Excluding 12 due to unsold and lots of lower sales, helps neaten the range too

Thanks =)
