Trade times never altered in repeat notice (15)

I believe the answer is:

readvertisement

'repeat notice' is the definition.
(a second advertisement or notice)

'trade times never altered' is the wordplay.
'altered' is an anagram indicator.
'trade'+'times'+'never'='tradetimesnever'
'tradetimesnever' with letters rearranged gives 'READVERTISEMENT'.

'in' is the link.

I've seen this clue in The Telegraph.
