A type of quote that gives both the bid and the ask price of a security, informing would-be traders of the current price at which they could buy or sell the security. The two-way quote also shows the spread between the bid and the ask, giving traders an idea of the current liquidity in the security (a smaller spread indicates more liquidity).






Taobiz explains Two-Way Quote
This type of quote provides more information to users than a last-trade quote, which quotes only the price at which the security last traded.

An example of a two-way quote would be: Citigroup quote of $52.50/$53.30.
This tells traders they can currently purchase Citigroup shares for $53.30 or sell them for $52.50. The spread between the bid and the ask is $0.80 ($53.30-$52.50).
