The Order Types feature in a Decentralized Exchange (DEX) allows users to execute trades using different strategies by providing multiple order types. This includes limit orders, which enable users to set a specific price at which they want to buy or sell an asset; market orders, which execute trades at the current market price; and stop-loss orders, which help traders minimize losses by automatically selling an asset when it reaches a certain price. This feature enhances user experience by offering flexibility and control over trading activities, catering to both novice and experienced traders.
