A scalp trader can look to make money in a variety of ways. One method is to have a set profit target amount per trade. This profit target should be relative to the price of the security and can range between .%1 - .25%. Another method is to track stocks breaking out to new intra-day highs or lows and utilizing Level II to capture as much profit as possible. This method requires an enormous amount of concentration and flawless order execution. Lastly, some scalp traders will follow the news and trade upcoming or current events that can cause increased volatility in a stock.
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.
