Keys were 1.83 USD on 1/8/2022. Graph does not extend to 1/4/2022, but due to the consistent flat line at the time it was most likely 1.83 USD as well.

9.99/1.83 = 5.459 keys, rounding to 5.46 keys(5.6 x2)

Keys were 1.64, 1.58, and 1.58 USD respectively

17.99/1.64 = 10.9695 keys, rounding to 10.97 keys (11 keys)

15.95/1.58 = 10.0949 keys, rounding to 10.09 keys(10 keys)

5.01/1.58 = 3.1708 keys, rounding to 3.17 keys(3.2 keys)

Think this is good enough

Sales at(with rounding): 3.6, 3.9, 4.6, 3.2, 3.5, 5.6, 3.2, 5.6, 11, 10

10 and 11 are excluded, far outside the rest of the sales. Buy orders at 3.59 keys, sellers at 4-5 keys. 3.6 keys seems alright for now. Excluding 3.2 keys

Taking range of 3.6 - 5.6 keys

Advice on range would be appreciated.
