Sales at: 371, 450, 577, 725. 371 is a quicksell.

Sellers at 1000. Buyer at 301. https://i.imgur.com/kc6c92a.png

Suggesting range from 450 to 725.

Sale 6 should support the range. Other sale on Banana is 650 which I guess could support the high end here (725). Sale 3 should support the low-end. Sale 4 should also support the low end but is better used on the casemaker.

Thanks to Sin, Foamy and Erik for their inputs.
