Trader

A trader is someone who buys and sells financial instruments, like stocks, currencies, futures, or options, with the goal of profiting from price changes over a relatively short period of time. This is different from an investor, who typically buys an asset and holds it for years, betting on the underlying business or economy growing over time. A trader is usually more focused on the price movement itself, whether that happens over minutes, days, or a few weeks.

Traders make money by buying low and selling high, or in some cases by selling first and buying back later at a lower price (called shorting). To do this repeatedly, they rely on analyzing charts, news, volume (how many shares or contracts are changing hands), and price patterns to decide when to enter and exit a position. Some traders act on their own, using their own money in a personal brokerage account; others trade for a bank, hedge fund, or trading firm using the firm's capital.

The word "trader" doesn't specify a timeframe or style on its own, which is why it's usually paired with a qualifier. A day trader closes all positions before the market closes each day. A swing trader might hold for several days to weeks. A scalper looks for tiny, fast price moves and may be in and out of a position in seconds. Someone described simply as "a trader" could be any of these, so context usually fills in the details.

The nuance beginners often miss is that being a trader is not just an activity, it's sometimes a legal and tax classification too. Some jurisdictions and brokers use specific rules to define who counts as a "trader" versus an "investor," and that classification can affect things like margin privileges, tax treatment, or account restrictions such as pattern day trader rules. Those specifics vary by country and change over time, so they're worth checking directly rather than assuming.
