Some of the common mistakes that scalpers make are poor execution, poor strategy, not taking stop-losses, over-leveraging, late entries, late exits and overtrading. Scalping generates heavy commissions due to the high number of transactions. A per-share commission pricing structure is beneficial to scalpers, especially for those who tend to scale smaller pieces in and out of positions.
But this description of swing trading is a simplification. In reality, swing trading sits in the middle of the continuum between day trading to trend trading. A day trader will hold a stock anywhere from a few seconds to a few hours but never more than a day; a trend trader examines the long-term fundamental trends of a stock or index and may hold the stock for a few weeks or months. Swing traders hold a particular stock for a period of time, generally a few days to two or three weeks, which is between those extremes, and they will trade the stock on the basis of its intra-week or intra-month oscillations between optimism and pessimism.
Many swing traders assess trades on a risk/reward basis. By analyzing the chart of an asset they determine where they will enter, where they will place a stop loss, and then anticipate where they can get out with a profit. If they are risking $1 per share on a setup that could reasonably produce a $3 gain, that is a favorable risk/reward. On the other hand, risking $1 to make $1 or only make $0.75 isn't as favorable.
Intraday traders always face inherent risks that exist in the stock markets. Price volatility and daily volume are a couple of factors that play an important role in the stocks picked for daily trading. Traders must not risk over two per cent of their total trading capital on a single trade to ensure the right risk management. So here are a few tips shared to make profit in intraday trading.

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 March 2000, this bubble burst, and a large number of less-experienced day traders began to lose money as fast, or faster, than they had made during the buying frenzy. The NASDAQ crashed from 5000 back to 1200; many of the less-experienced traders went broke, although obviously it was possible to have made a fortune during that time by short selling or playing on volatility.[9][10]

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.
This often means trading shares of companies that have just released breaking news, reported earnings, or have another fundamental catalyst that is resulting in above average retail interest. The type of stocks a day trader will focus on are typically much different from what a long term investor would look for. Day traders acknowledge the high levels of risk associated with trading volatile markets and they mitigate those risks by holding positions for very short periods of time.
The swing trader, therefore, is best positioned when markets are going nowhere – when indexes rise for a couple of days, then decline for the next few days, only to repeat the same general pattern again and again. A couple of months might pass with major stocks and indexes roughly at the same place as their original levels, but the swing trader has had many opportunities to catch the short-term movements up and down (sometimes within a channel).
You're probably looking for deals and low prices, but stay away from penny stocks. These stocks are often illiquid, and chances of hitting a jackpot are often bleak. Many stocks trading under $5 a share become de-listed from major stock exchanges and are only tradable over-the-counter (OTC). Unless you see a real opportunity and have done your research, stay clear of these.
