Hi
These are unmanaged markets. In the market rules for each market like this Betfair will say:
"This market will not be actively managed by Betfair, therefore it is the responsibility of customers to manage their own positions."
Tim is correct that these markets cannot be identified through Betfair data. However, if you log in to the Betfair website and use their search box to search for "unmanaged" without the quotes, you should get a list of these markets.
