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.
Another risk of swing trading is that sudden reversals can create losing positions. Because you are not trading all throughout the day, it can be easy to be caught off guard if price trends do not play out as planned. To decrease the risk of this happening, we recommend issuing stop orders with every new position. Stop orders can help you “lock-in” your gains and can also help you cut your losses.
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.
