An “at best” order instructs a broker to buy or sell an asset at the best available market price. While execution is fast, no specific price is guaranteed, as the order is filled at prevailing market conditions.

An “at or better” order directs the broker to execute a trade at a specified price or a more favorable one. As a type of limit order, it may take time to execute or may not be filled if the price is never reached.
