What is the primary difference between a market order and a limit order in trading?

• A. Market orders guarantee price; limit orders guarantee execution
• B. Market orders execute immediately at the best available price; limit orders specify a price and may not fill
• C. Market orders are only for stocks; limit orders for bonds
• D. Market orders are never affected by liquidity; limit orders are

Answer: (B)

The key idea is speed versus price control. A market order tells your broker to buy or sell right away at whatever price is currently available, so you get a quick fill, but the exact price isn’t controlled and can slip, especially if the market moves fast or isn’t very liquid. A limit order sets the price at which you’re willing to trade and will only execute if the market reaches that price or better. You gain price certainty, but there’s no guarantee the order will be filled if the market never hits your limit. That’s why the primary difference is that market orders prioritize immediate execution at the best available price, while limit orders prioritize the price you’re willing to trade at and may not fill. In practice, liquidity matters: in a liquid market a market order fills quickly near the quoted price with little slippage; in a thin market, a market order can move the price and a limit order might not fill at all. The other statements misstate the relationship: market orders don’t guarantee price, and limit orders don’t guarantee execution; trading concepts like these apply across assets, not just stocks; and liquidity affects both types of orders.
