Not recognising central unit's position during trade (2,6)
I believe the answer is:
in denial
'not recognising' is the definition.
(someone in denial refuses to recognise something)
'central unit's position during trade' is the wordplay.
I cannot really understand how this works, but
'during' could be 'in' (e.g. during February means in February) and 'in' is located in the answer.
'unit' could be 'n' (N is an example) and 'n' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for in denial that I've seen before include "Not facing painful truth" , "Refusing to acknowledge reality, living in illusion" , "Refusing to come to terms with a painful reality" .)
