Order Types: Market Orders vs. Limit Orders Execution Priorities
A customer observes that a volatile technology stock is dropping rapidly in morning trading and instructs their representative: 'Sell my 500 shares immediately; I want out right now regardless of the price!' Which order type must the representative enter, and what are its trade execution characteristics?
A Market Order guarantees execution certainty at the prevailing market price, but provides ZERO price certainty. A Limit Order guarantees price, but not execution.
Complete Analysis & Legal Rationale
This is a fundamental trading distinction: (1) Market Order: An order to buy or sell immediately at the best available bid (for sells) or ask (for buys). It guarantees execution certainty, but offers NO price certainty (in fast-moving markets, the execution price may differ significantly from the quote seen at order entry); (2) Limit Order: An order to buy or sell at a specified price or better (Buy Limit at or below limit; Sell Limit at or above limit). It guarantees price certainty, but carries execution risk if the market never reaches the limit.
