The following are several basic trading strategies by which day traders attempt to make profits. In addition, some day traders also use contrarian investing strategies (more commonly seen in algorithmic trading) to trade specifically against irrational behavior from day traders using the approaches below. It is important for a trader to remain flexible and adjust techniques to match changing market conditions.
Day trading requires more money than just a deposit, though. Get setup with a good computer, one or two monitors, a trading platform and data feeds. With many brokers the data feeds for various markets cost money, so pick a market and stick with it. There is no reason to pay for data feeds you won't be using. Also, a consistent income isn't likely during the first six months to a year, so save up for living expenses if attempting to day trade as a primary income stream.
Assess how much capital you're willing to risk on each trade. Many successful day traders risk less than 1% to 2% of their account per trade. If you have a $40,000 trading account and are willing to risk 0.5% of your capital on each trade, your maximum loss per trade is $200 (0.005 x $40,000). Set aside a surplus amount of funds you can trade with and you're prepared to lose. Remember, it may or may not happen.
