There is a commonly quoted statistic that only about 5 percent of day traders succeed. This is a good approximation. Most people who try day trading will not succeed, yet most of them do not practice everyday for six months to a year either. Time investment and quality practice increase a day traders chances of being in the 5 percent that are successful.
To offset this, day traders are often offered the "opportunity" to leverage their portfolios with more margin, four times the buying power rather than double. Taking larger leveraged positions can increase percentage gains to offset costs. The problem is that no one is right all the time. A lack of focus, discipline, or just plain bad luck can lead to a trade that goes against you in a big way. A bad trade, or string of bad trades, can blow up your account, where the loss to the portfolio is so great the chances of recovery are slim. For a swing trader, a string of losses or a big loss can still have a dramatic effect, but the lower leverage reduces the likelihood that the results wipe out your portfolio.

Once again, you should only enter a swing trade after you have evaluated the potential risk and reward.As with bullish swing trades, the entry point would be compared to the stop out and profit target points to analyze the potential rewards and risks of the trade. On a bearish swing trade, the stop out point is the highest price of the recent counter trend. So if the stock rose higher than this price, you would exit the trade to minimize losses. The profit target is the lowest price of the recent downtrend. So if the stock reached this price or lower, you should consider exiting at least some of the position to lock in some gains.
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.
