Market order / Limit order

An order executed immediately at the current price vs. only at a specified price.

A market order says “fill me now at the best available price.” It prioritizes speed over exact price control. A limit order says “only fill at this price or better,” so you control the price but might not get filled if the market never reaches your level.

Beginners often use market orders for liquid instruments when they care more about being in or out than about a few cents. Limit orders help when you want a specific entry or exit and are willing to wait.

Example

You want stock XYZ near $50. A limit buy at $50 may sit unfilled if the price stays at $50.40. A market buy fills immediately around the current ask — even if that ask is $50.40.
