Forex differs from stock markets in several fundamental ways that beginners consistently underestimate. It operates twenty-four hours a day five days a week across global sessions, meaning price action happens continuously rather than only during fixed exchange hours. Currency pairs move in pips rather than dollar amounts, and positions are typically sized in lots which introduces leverage mechanics that feel unfamiliar initially. Most importantly, forex is a zero-sum market in the short term meaning every profitable trade has a counterparty taking a loss, which creates a competitive dynamic quite different from equity investing where rising tides can lift all boats simultaneously.
