Set a limit on the number of shares and/or dollar value of any single
        order placed for sid.  Limits are treated as absolute values and are
        enforced at the time that the algo attempts to place an order for sid.

        If an algorithm attempts to place an order that would result in
        exceeding one of these limits, raise a TradingControlException.

        Parameters
        ----------
        asset : Asset, optional
            If provided, this sets the guard only on positions in the given
            asset.
        max_shares : int, optional
            The maximum number of shares that can be ordered at one time.
        max_notional : float, optional
            The maximum value that can be ordered at one time.
