Dealers' highest bid and lowest ask is known as either an inside quote or a market quote. A market order means that a dealer pays bid when buying, while a dealer receives ask when selling. The difference between the bid and ask is the dealer's profits. The system utilizes the market order, although limit orders are also possible. Since the model takes the form of placing a basket order either to buy or sell, the TaraFolioTM engine can best be utilized if market orders are used instead of limit orders. The chances of having orders simultaneously executed will be much greater with market orders.
