A market in which the market makers are only able to offer a single price, instead of both the asking and the bid prices, is referred to as a One-sided Market or a One-way Market. This can occur when there is a lack of liquidity or interest in a particular security. In such cases, the market maker may only be able to offer a price at which they are willing to buy or sell, rather than providing both options. This can impact the overall efficiency and fairness of the market, making it important for investors to be aware of such conditions.
