Smaller moves, easier to obtain - A change in price results from imbalance of buying and selling powers. Most of the time within a day, prices stay stable, moving within a small range. This means neither buying nor selling power control the situation. There are only a few times which price moves towards one direction, i.e. either buying or selling power controls the situation. It requires bigger imbalances for bigger price changes. It is what scalpers look for - capturing smaller moves which happen most of the time, as opposed to larger ones.
Spreads are bonuses as well as costs - Stock Markets operate on a bid and ask based system. The numerical difference between the bid and ask prices is referred to as the spread between them. The ask prices are immediate execution (market) prices for quick buyers (ask takers); bid prices for quick sellers (bid takers). If a trade is executed at market prices, closing that trade immediately without queuing would not get you back the amount paid because of the bid/ask difference. The spread can be viewed as trading bonuses or costs according to different parties and different strategies. On one hand, traders who do NOT wish to queue their order, instead paying the market price, pay the spreads (costs). On the other hand, traders who wish to queue and wait for execution receive the spreads (bonuses). Some day trading strategies attempt to capture the spread as additional, or even the only, profits for successful trades.

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.
Market data is necessary for day traders to be competitive. A real-time data feed requires paying fees to the respective stock exchanges, usually combined with the broker's charges; these fees are usually very low compared to the other costs of trading. The fees may be waived for promotional purposes or for customers meeting a minimum monthly volume of trades. Even a moderately active day trader can expect to meet these requirements, making the basic data feed essentially "free". In addition to the raw market data, some traders purchase more advanced data feeds that include historical data and features such as scanning large numbers of stocks in the live market for unusual activity. Complicated analysis and charting software are other popular additions. These types of systems can cost from tens to hundreds of dollars per month to access.[19]

Trend Trading is a strategy where it is believed that a stock that is rising will continue to rise, or a stock that is falling will continue to fall. You enter the trade in the direction of the trend and exit once the price breaks this trend. Trend trading usually incorporates the use of trend and support/resistance lines.
