Market Order
A market order tells your broker: buy (or sell) right now at whatever the current price is. It's fast and virtually certain to execute — but on a jumpy stock, 'the current price' can shift between your click and the actual fill. For calm, heavily traded stocks, the difference is pennies.
Example: A stock quoted at $50.00–$50.05 might fill your market buy at $50.06 if the price ticks up mid-order.
