What is the difference between a price-driven trading system and an order-driven trading system?
A price-driven trading system and an order-driven trading system represent two distinct mechanisms for executing trades in financial markets.
A price-driven trading system, also known as a quote-driven or dealer market, is characterized by market makers or dealers who provide buy and sell quotes for securities. These dealers are ready to buy securities at a specified bid price and sell at a specified ask price, profiting from the spread between these two prices. This system is prevalent in over-the-counter (OTC) markets, where the liquidity provided by dealers ensures that trades can be executed quickly. The key advantage is the ability to transact swiftly, but it relies on the presence and willingness of dealers to facilitate trades.
In contrast, an order-driven trading system, common in exchanges like the New York Stock Exchange (NYSE) and Nasdaq, matches buy and sell orders from market participants. Orders are placed into an order book, where they are matched based on price and time priority. This system provides transparency, as all buy and sell orders are visible to market participants, promoting a fair and competitive trading environment. The primary advantage of an order-driven system is its transparency and fairness, as prices are determined by actual supply and demand rather than dealer quotes. However, it can suffer from lower liquidity compared to price-driven systems, particularly for less actively traded securities.
In summary, the main difference lies in the source of liquidity and price determination: price-driven systems rely on dealers to set prices and provide liquidity, while order-driven systems depend on the collective actions of market participants to determine prices and match orders.
