Stop changing position (4)

I believe the answer is:

post

'position' is the definition.
(I know that position can be written as post)

'stop changing' is the wordplay.
'changing' is an anagram indicator.
'stop' anagrammed gives 'POST'.

(Other definitions for post that I've seen before include "Prevent (cheque) being cashed immediately" , "Leave message online" , "Publish' mail' job" , "employment" , "Publicly display; send" .)

I've seen this clue in the Evening Standard.
