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.
Your account will be designated as “day trader status” if you have 3 round trip trades (one round trip = an opening and closing transaction), in a rolling 5 business day period. If you have 4 round trip trades in a 5 day period, you will be restricted from day trading for 90 days. Your brokerage firm will probably allow you to buy a stock and hold it overnight before closing the position. If you have a second day trade violation, your account will either be restricted from trading or you can request your account be a non day trader status account and buy and then sell after 3 business days. This depends upon the specific brokerage firms rules for some of these details but they are getting very strict with enforcing these rules.

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.

Successful traders have to move fast, but they don't have to think fast. Why? Because they've developed a trading strategy in advance, along with the discipline to stick to that strategy. It is important to follow your formula closely rather than try to chase profits. Don't let your emotions get the best of you and abandon your strategy. There's a mantra among day traders: "Plan your trade and trade your plan."
