Introduction
A Quote-Driven System is a traditional financial trading system in which designated market makers continuously provide bid (buy) and ask (sell) prices for a security. This system is also known as a “dealer market,” and it is fundamental to understanding how liquidity is maintained in certain markets.
Historical Context
The quote-driven system has been prevalent since the inception of modern financial markets. Historical instances of quote-driven trading can be traced back to the early stock exchanges in London and New York during the 18th and 19th centuries. Market makers played a crucial role in facilitating trades by ensuring liquidity and stability.
Types/Categories
- Single Market Maker Systems: One market maker is responsible for providing quotes for a specific security.
- Multiple Market Maker Systems: Multiple market makers provide competing quotes, leading to tighter spreads and more competitive pricing.
- Inter-dealer Systems: Only dealers interact with one another to provide quotes, with the public unable to directly see these quotes.
Key Events
- NYSE Specialist System: Since the New York Stock Exchange’s establishment, specialists have been integral, providing continuous quotes and facilitating trades.
- NASDAQ: In the 1970s, NASDAQ introduced a computerized system with multiple market makers quoting securities, improving efficiency and transparency.
Detailed Explanation
Structure and Function
Market makers are financial institutions or individuals responsible for maintaining a ready supply of a particular asset, such as stocks, bonds, or currencies. They provide liquidity by standing ready to buy or sell at publicly quoted prices.
Process
- Quote Posting: Market makers post their bid and ask prices.
- Order Matching: When traders accept these prices, the trades are executed.
- Inventory Management: Market makers manage their inventory to balance their holdings and mitigate risks.
Mathematical Models
Mathematical models are essential for market makers to determine optimal quoting strategies.
Spread Calculation
Inventory Management Model
- \( \pi \) = profit
- \( P \) = price of the security
- \( Q \) = quantity
- \( c(Q) \) = cost function related to inventory
Importance and Applicability
- Liquidity: Ensures continuous trading opportunities by providing buy/sell quotes.
- Stability: Reduces volatility by facilitating smoother price movements.
- Efficiency: Streamlines trading processes, benefiting both institutional and retail investors.

Considerations
