Currency day trading involves buying and selling currencies within the same calendar day, with all trades completed by the end of the day. Laws passed six years ago enabled small investors and individuals to engage in currency day trading, which was previously only done by large banks, financial institutions, and millionaires. Currency day traders have vast buying power that allows them to control much larger investments than the amount invested. Most professional day traders work for larger institutions, which provide greater resources like capital, software, and direct access to dealing desks, while individual traders have more limited resources and cannot compete directly with institutional traders. Various software and websites exist to help people learn about currency day trading practices.
