Array-formula in F2 (Price)
=MAX(IF($H$2:$H$4>=MIN(A2,C2),IF($H$2:$H$4<=MAX(A2,C2),$I$2:$I$4)))
confirmed with Ctrl+Shift+Enter
(hold down both Ctrl and Shift keys and hit Enter)
Formula in E2 (Max Date)
=INDEX($H$2:$H$4,MATCH(F2,$I$2:$I$4,0))
To simplify i assumed that the table is in the same sheet - adjust the range accordingly (another sheet).
