Sales:

6 @ 7 ref

320 @ 6 ref

9 @ 5.88 ref

3 @ 5.55 ref

4 @ 5.33 ref

6 @ 5.11 ref

207 @ 5 ref

5 @ 4.88 ref

1 @ 4.05 ref

Buys:

354 @ 4 ref

36 @ 3.77 ref

104 @ 3.66 ref

Most common trading point seems to be 4-6 ref. Buyers are at around 4-4.11 ref. 6 sales at 7 doesn't seem enough to justify including in the range, especially given the fact the sales at 3.66 and 3.77 are being excluded.

Sticking with 4-6 ref
