• by_book –

  Return all positions in book_type.

• by_instrument –

  Return all positions for instrument_id.

• by_side –

  Return all positions with side.

• by_status –

  Return all positions with status.

• close –

  Set position status to CLOSED and rebuild its index entries.

• get –

  Return the position for position_id; raise KeyError if absent.

• open_positions –

  Shortcut for by_status(PositionStatus.OPEN).

• query –

  Return positions matching all non-None filter parameters.
