What Is an Order Driven Market?
Let me explain what an order-driven market is. It's a financial market where you, as a buyer or seller, display the prices you're willing to buy or sell a security at, along with the amounts you want to trade. This setup is the direct opposite of a quote-driven market, where only the bids and asks from designated market makers and specialists are shown for that security.
Key Takeaways
In an order-driven market, trades happen based on what buyers and sellers want, with their bid and ask prices and share quantities openly displayed. This contrasts with quote-driven markets, where market makers—dealers and specialists—set the trades by filling orders from their inventory or matching them. You deal with two main order types here: market orders and limit orders. Remember, these markets are generally less liquid but more transparent than quote-driven ones.
Understanding an Order Driven Market
Order-driven markets run on a steady stream of buy and sell orders from participants like you. There are no designated liquidity providers, and the core orders are market orders and limit orders. In contrast, quote-driven markets have market makers offering bids and asks that others can trade against.
The main benefit of an order-driven market is its transparency, as the full order book is available for investors who want to see it—though most exchanges charge for this access.
However, liquidity might not be as strong here compared to quote-driven markets, where specialists and market makers must trade at their posted prices.
Fast Fact
Stock exchanges such as the New York Stock Exchange and Nasdaq operate as hybrid markets, blending elements of both order-driven and quote-driven systems.
How Informed Trading Affects Order-Driven Markets
In order-driven settings, you can choose market orders that take liquidity or limit orders that provide it. Informed trading can actually increase liquidity in these environments.
A greater presence of informed traders improves liquidity, as measured by tighter bid-ask spreads and stronger market resiliency. That said, informed traders don't influence the price impact of orders. Limit orders have about a quarter of the price impact compared to market orders.
How Order Driven Environments Rank Buy and Sell Orders
Order-driven systems rank your buy and sell orders by price, matching the highest-ranked ones at the minimum amount if possible. If there's leftover volume, the system matches it with the next best order.
The primary rule is price priority, with secondary rules deciding ties at the same price. Typically, the first order at the best price gets priority, but sometimes displayed quantities trade before hidden ones at that price.
