The first 9 successful trades produce $900 in profit. On the 10th trade, when the position is down $50, instead of except the loss the untrained trader purchases more shares at a lower price to reduce his cost basis. Once he is down $100, he continues to hold and is unsure of whether to hold or sell. The trader finally takes the loss when he is down $1,000.
Swing trading is actually one of the best trading styles for the beginning trader to get his or her feet wet, but it still offers significant profit potential for intermediate and advanced traders. Swing traders receive sufficient feedback on their trades after a couple of days to keep them motivated, but their long and short positions of several days are of the duration that does not lead to distraction. By contrast, trend trading offers greater profit potential if a trader is able to catch a major market trend of weeks or months, but few are the traders with sufficient discipline to hold a position that long without getting distracted. On the other hand, trading dozens of stocks per day (day trading) may just prove too white-knuckle of a ride for some, making swing trading the perfect medium between the extremes.
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.
