A day trader is an individual who buys and sells financial instruments, such as stocks, currencies, or commodities, within the same trading day, with the intention of making a profit from the price movements during the day. Day traders typically make many trades during the day and close all their positions by the end of the trading day to avoid overnight market risks. Day trading requires a significant amount of time, attention, and skill, and is typically done by experienced traders who use technical analysis, fundamental analysis, or a combination of both to identify trading opportunities. Day trading is also associated with high risks due to the volatility of the markets, and traders must be able to manage their risk effectively to be successful.
