Market Order
Order Types & Execution
A market order is an instruction to buy or sell immediately at the best available current price, prioritizing speed of execution over price certainty.
What is a market order?
A market order tells your broker to buy or sell a specific volume of an instrument right now, at whatever price is currently available — instead of waiting for the market to reach a price you choose. It’s the simplest and fastest way to enter or exit a trade, which makes it the default order type most beginners use first.
How a market order fills
When you submit a market order, your platform sends it to the broker for immediate execution against the current bid (sell) or ask (buy) price. Because prices update continuously, even a fraction of a second can separate the price you saw on screen from the price you actually get filled at. That gap is called slippage, and it tends to grow during fast or thin markets, such as around major news releases.
For example, if EUR/USD is quoted at 1.0850 (bid) / 1.0852 (ask) and you place a market buy order, you would expect to be filled near 1.0852. In a calm market that’s usually exactly what happens; in a volatile one, you might instead be filled at 1.0853 or 1.0854 as the price moves during the split-second it takes to execute.
Market order vs. limit order
A market order guarantees you get into or out of a trade quickly, but not at a guaranteed price. A limit order, by contrast, guarantees the price (or better) but not that the trade will happen at all, since the market may never reach your chosen level. Traders typically choose a market order when speed matters more than a precise entry price — for instance, closing a position quickly during unexpected volatility.
Why it matters
The quality of a broker’s order execution — how fast and how consistently it fills market orders near the quoted price — directly affects real trading costs. Two brokers can advertise the same headline spread yet deliver very different results if one has noticeably worse slippage on market orders. This is one of several practical details worth checking in a broker’s execution policy or independent reviews before relying on market orders for time-sensitive trades.
Trading carries a high level of risk and may not be suitable for all investors. Past performance is not indicative of future results.
