Order types in trading define how and when your trades execute. The most common are market orders, which buy or sell immediately at the best available price, and limit orders, which set a specific price at which you want to trade. Stop orders activate trades once a certain price threshold is reached, useful for limiting losses or securing profits. Understanding different order types empowers traders to better manage risks and optimize entry and exit points. Proper use of orders can make the difference between profit and loss in volatile crypto markets.
