fn get_open_positions<'a, Markets: Iterator<Item = &'a Market>>(
    &mut self,
    engine_id: Uuid,
    markets: Markets
) -> Result<Vec<Position>, RepositoryError>

Get all open Positions associated with a Portfolio.

fn remove_position(
    &mut self,
    position_id: &PositionId
) -> Result<Option<Position>, RepositoryError>

fn set_exited_position(
    &mut self,
    engine_id: Uuid,
    position: Position
) -> Result<(), RepositoryError>
