Bad trade died when hurried (6)
I believe the answer is:
darted
'hurried' is the definition.
(darting is a kind of hurrying)
'bad trade died' is the wordplay.
'bad' is an anagram indicator.
'died' becomes 'd'.
'trade' anagrammed gives 'darte'.
'darte'+'d'='DARTED'
'when' acts as a link.
(Other definitions for darted that I've seen before include "Moved suddenly like game missile" , "Dashed, on the electric train?" , "Sniped" , "Moved quickly and suddenly" , "Moved rapidly and lightly" .)
