By holding overnight, the swing trader incurs the unpredictability of overnight risk such as gaps up or down against the position. By taking on the overnight risk, swing trades are usually done with a smaller position size compared to day trading (assuming the two traders have similarly sized accounts). Day traders typically utilize larger position sizes and may use day trading margin of 25%.

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.

Of course, you still have to factor in losses. Smaller gains can only produce growth in your portfolio if losses are kept small. Rather than the normal 7% to 8% stop loss, take losses quicker at a maximum of 2% to 3%. This will keep you at a 3-to-1 profit-to-loss ratio, a sound portfolio management rule for success. It's a critical component of the whole system since an outsized loss can quickly wipe away a lot of progress made with smaller gains.

Day trading is not for everyone and involves significant risks. Moreover, it requires an in-depth understanding of how the markets work and various strategies for profiting in the short term. While we remember the success stories of those who struck it rich as a day trader, remember that most do not—many will fizzle out and many will just barely stay afloat. Furthermore, don't underestimate the role that luck and good timing play—while skill is certainly an element, a rout of bad luck can sink even the most experienced day trader.

Scalpers buy low and sell high, buy high and sell higher, or short high and cover low, or short low and cover lower. They tend to utilize Level 2 and time of sales windows to route orders to the most liquid market makers and ECNs for quick executions. The point-and-click style execution through the Level 2 window or pre-programmed hotkeys are the quickest methods for the speediest order fills. Scalping is purely based on technical analysis and short-term price fluctuations. Due to the extensive use of leverage, scalping is considered a high-risk style of trading.
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.
Rebate trading is an equity trading style that uses ECN rebates as a primary source of profit and revenue. Most ECNs charge commissions to customers who want to have their orders filled immediately at the best prices available, but the ECNs pay commissions to buyers or sellers who "add liquidity" by placing limit orders that create "market-making" in a security. Rebate traders seek to make money from these rebates and will usually maximize their returns by trading low priced, high volume stocks. This enables them to trade more shares and contribute more liquidity with a set amount of capital, while limiting the risk that they will not be able to exit a position in the stock.[16]
In addition to knowledge of basic trading procedures, day traders need to keep up on the latest stock market news and events that affect stocks—the Fed's interest rate plans, the economic outlook, etc. So do your homework. Make a wish list of stocks you'd like to trade and keep yourself informed about the selected companies and general markets. Scan business news and visit reliable financial websites.
