The best way is via the Portfolio which acts as a manager of sorts for all of the accounting:

self.portfolio.account(venue)

Or these methods and properties are available:

cdef class PortfolioFacade:

    cdef readonly bint initialized
    """If the portfolio is initialized.\n\n:returns: `bool`"""

    cdef readonly analyzer
    """The portfolios analyzer.\n\n:returns: `PortfolioAnalyzer`"""

    cpdef Account account(self, Venue venue)

    cpdef dict balances_locked(self, Venue venue)
    cpdef dict margins_init(self, Venue venue)
    cpdef dict margins_maint(self, Venue venue)
    cpdef dict unrealized_pnls(self, Venue venue)
    cpdef dict net_exposures(self, Venue venue)

    cpdef Money unrealized_pnl(self, InstrumentId instrument_id)
    cpdef Money net_exposure(self, InstrumentId instrument_id)
    cpdef object net_position(self, InstrumentId instrument_id)

    cpdef bint is_net_long(self, InstrumentId instrument_id) except *
    cpdef bint is_net_short(self, InstrumentId instrument_id) except *
    cpdef bint is_flat(self, InstrumentId instrument_id) except *
    cpdef bint is_completely_flat(self) except *
