Individual traders often manage other people's money or simply trade with their own. Few of them have access to a trading desk, but they often have strong ties to a brokerage (due to the large amounts they spend on commissions) and access to other resources. However, the limited scope of these resources prevents them from competing directly with institutional day traders. Instead, they are forced to take more risks. Individual traders typically day trade using technical analysis and swing trades—combined with some leverage—to generate adequate profits on such small price movements in highly liquid stocks.
Spot foreign exchange (exchanges of foreign currencies) brokers - They do not charge any commissions because they make profits from the bid/ask spread quotes. On July 10, 2006, the exchange rate between Euro and United States dollar is 1.2733 at 15:45. The internal (inter-bank dealers) bid/ask price is 1.2732-5/1.2733-5. However the foreign exchange brokers or middlemen will not offer the same competitive prices to their clients. Instead they provide their own version of bid and ask quotes, say 1.2731/1.2734, of which their commissions are already "hidden" in it. More competitive brokers do not charge more than 2 pips spread on a currency where the interbank market has a 1 pip spread, and some offer better than this by quoting prices in fractional pips.
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.
Volatility is the name of the day-trading game. Day traders rely heavily on a stock’s or market’s fluctuations to earn their profits. They like stocks that bounce around a lot throughout the day, whatever the cause: a good or bad earnings report, positive or negative news, or just general market sentiment. They also like highly liquid stocks, ones that allow them to move in and out of a position without much affecting the stock’s price.
Because scalpers focus on short-term positions with low-profit margins, the best scalping strategies (such as the Triple S strategy mentioned below) require some leverage. It's recommended that scalpers start with a large amount of capital. Opening and closing larger positions allow you to reduce the marginal costs of trading and maximize potential gains.
Fundamental analysis usually involves using a company's financial statements, discounted cash flow modeling and other tools to assess a company's intrinsic value. Scalpers may trade on news or events that drastically affect a company’s value immediately after its release. In some cases, they may also use short term changes in fundamental ratios to scalp trades but typically they focus mostly on the technical charts.
Sincere interviewed professional day trader John Kurisko, Sincere states, Kurisko believes that some of the reversals can be blamed on traders using high-speed computers with black-box algorithms scalping for pennies. “That’s one of the reasons many traders get frustrated with the market. The timing is not like it used to be, and many of the old rules don’t work like before.” 
Liquidity - The liquidity of a market affects the performance of scalping. Each product within the market receives different spread, due to popularity differentials. The more liquid the markets and the products are, the tighter the spreads are. Some scalpers like to trade in a more liquid market since they can move in and out of large positions easily without adverse market impact. Other scalpers like to trade in less liquid markets, which typically have significantly larger bid-ask spreads. Whereas a scalper in a highly liquid market (for example, a market maintaining a one-penny spread) may take 10,000 shares to make a 3 cent gain ($300), a scalper in an illiquid market (for example, a market with a 25 cent spread) may take 500 shares for a 60 cent gain ($300). While there is theoretically more profit potential in a liquid market, it is also a "poker game" with many more professional players which can make it more difficult to anticipate future price action.
Scalping is the shortest time frame in trading and it exploits small changes in currency prices. Scalpers attempt to act like traditional market makers or specialists. To make the spread means to buy at the Bid price and sell at the Ask price, in order to gain the bid/ask difference. This procedure allows for profit even when the bid and ask don't move at all, as long as there are traders who are willing to take market prices. It normally involves establishing and liquidating a position quickly, usually within minutes or even seconds.
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.
A basic EMA crossover system can be used by focusing on the nine-, 13- and 50-period EMAs. A bullish crossover occurs when the price crosses above these moving averages after being below. This signifies that a reversal may be in the cards and that an uptrend may be beginning. When the nine-period EMA crosses above the 13-period EMA, it signals a long entry. However, the 13-period EMA has to be above the 50-period EMA or cross above it.
But there is an added risk with the shorter time frame. A wide spread between the bid, the ask and commissions can eat too large a portion of your profits. Swing traders can struggle with this too, but the effect is amplified for the day trader. Day traders can find themselves doing all the work, and the market makers and brokers reap the benefits.
