How can I open an account to buy stocks over the Internet?

Nevertheless day trading can become very risky, especially if one has poor discipline, risk or money management. The common use of buying on margin (using borrowed funds) amplifies gains and losses, such that substantial losses or gains can occur in a very short period of time. In addition, a broker usually allow more margins for daytraders. Where overnight margin required to hold a stock position is normally 50% of the stock's value, many brokers allow pattern day trader accounts to use levels as low as 25% for intraday purchases. That means even a day trader with the minimum $25,000 in his account can buy $100,000 worth of stock during the day, as long as half of those positions are exited before the market close. Thus a day trader has to admit mistakes quickly and cut losses fast when the market goes against a position.
