Before day trading, if someone wanted to trade a stock, they needed to call a stock broker to place their order, who would then route the order through a specialist on the floor of the exchange. The specialist would match the buyer with a seller and write up a physical ticket that would transfer the stock and send that confirmation back to both brokers. Commissions were charged at a flat rate of 1% of the total amount of the trade. That means that to buy $10,000 worth of stock, it would cost you an additional $100 in commissions. In 1975, the SEC (Securities and Exchange Commission) made fixed commission rates illegal opening up the markets to the first of the discount brokers competing for business by lowering their commissions and making short term trading much more profitable.
There are two primary divisions of professional day traders: those who work alone and/or those who work for a larger institution. Most day traders who trade for a living work for a large institution. These traders have an advantage because they have access to a direct line, a trading desk, large amounts of capital and leverage, expensive analytical software, and much more. These traders are typically looking for easy profits that can be made from arbitrage opportunities and news events, and these resources allow them to capitalize on these less risky day trades before individual traders can react.
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.
So, swing traders are not looking to hit the home run with a single trade – they are not concerned with the perfect time to buy a stock exactly at its bottom and sell exactly at its top (or vice versa). In a perfect trading environment, they wait for the stock to hit its baseline and confirm its direction before they make their moves. The story gets more complicated when a stronger uptrend or downtrend is at play: the trader may paradoxically go long when the stock dips below its EMA and wait for the stock to go back up in an uptrend, or he or she may short a stock that has stabbed above the EMA and wait for it to drop if the longer trend is down.
This trading strategy used to be defined as spread trading where you would take profits where small gaps expanded and contracted between the bid and the ask price for a stock. This strategy has now evolved to include technical indicators, support/resistance levels, and volume spikes to make round-trip trades lasting seconds to a few minutes. The basic idea of scalping is to take advantage of market inefficiencies using speed and high trading volume to create quick profits. Click here for more information on scalping.
Buying on margin can greatly increase your gains or losses. Brokerages usually allow a bigger margin percentage for a day trading account but reduce the amount of margin available for positions held overnight. Normally a day trading account must have a minimum of $25,000 and can buy on margin at a rate of 4 to 1 giving you $100,000 in buying power, which is called day trader buying power. That number drops to 2 to 1 for positions held overnight, which can be called overnight margin buying power. That means that if you have 100% of your margin being used during the day, you must exit at least half of your positions before the close of the trading day.

Price action trading relies on technical analysis but does not rely on conventional indicators. These traders rely on a combination of price movement, chart patterns, volume, and other raw market data to gauge whether or not they should take a trade. This is seen as a "simplistic" and "minimalist" approach to trading but is not by any means easier than any other trading methodology. It requires a solid background in understanding how markets work and the core principles within a market, but the good thing about this type of methodology is it will work in virtually any market that exists (stocks, foreign exchange, futures, gold, oil, etc.).
The difference between the profit target and the entry point is the approximate reward of the trade. The difference between the entry point and the stop out point is the approximate risk.When determining whether it’s worthwhile to enter a swing trade, consider using two-to-one as a minimum reward-to-risk ratio. Your potential profit should be at least twice as much as your potential loss. If the ratio is higher than that, the trade is considered better; if it’s lower it’s worse.
Swing traders usually go with the main trend of the stock. But some traders like to go against it and trade the counter trend instead. This is known as “fading,” but it has many other names: counter-trend trading, contrarian trading, and trading the fade. During an uptrend, you could take a bearish position near the swing high because you expect the stock to retrace and go back down. During a downtrend to trade the fade, you would buy shares near the swing low if you expect the stock to rebound and go back up.
Trading stocks intraday offers different opportunities than a traditional ‘buy and hold’ strategy. Speculating on stock prices via CFDs or spread betting for example, mean traders can profit from falling prices too. Margin or leverage also reduce the capital required to open a position. So you can take a position on the latest news release, product announcement or financial report – as well as technical indicators.

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.
Retail day traders are competing with professionals. Pros know the tricks and traps. They have expensive trading technology, data subscriptions and personal connections. They’re perfectly outfitted to succeed, and even then they often fail. Among these pros are high-frequency traders, who are looking to skim pennies or fractions of pennies — the day trader’s profit — off every trade. It’s a crowded field, and the pros love to have inexperienced investors join the fray. That helps them profit.
The basic strategy of news playing is to buy a stock which has just announced good news, or short sell on bad news. Such events provide enormous volatility in a stock and therefore the greatest chance for quick profits (or losses). Determining whether news is "good" or "bad" must be determined by the price action of the stock, because the market reaction may not match the tone of the news itself. This is because rumors or estimates of the event (like those issued by market and industry analysts) will already have been circulated before the official release, causing prices to move in anticipation. The price movement caused by the official news will therefore be determined by how good the news is relative to the market's expectations, not how good it is in absolute terms.

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.
Scalping is a fast-paced activity for nimble traders. It requires precision timing and execution. Scalpers use day trading buying power of four to one margin to maximize profits with the most shares in the shortest amount of holding time. This requires focusing on the smaller time frame interval charts such as the one-minute and five-minute candlestick charts. Momentum indicators such as stochastic, moving average convergence divergence (MACD) and relative strength index (RSI) are commonly used. Price chart indicators such as moving averages, Bollinger bands and pivot points are used as reference points for price support and resistance levels.
When it comes time to take profits, the swing trader will want to exit the trade as close as possible to the upper or lower channel line without being overly precise, which may cause the risk of missing the best opportunity. In a strong market when a stock is exhibiting a strong directional trend, traders can wait for the channel line to be reached before taking their profit, but in a weaker market, they may take their profits before the line is hit (in the event that the direction changes and the line does not get hit on that particular swing). 
Swing traders can use a wide array of technical indicators. What makes swing trading unique is that it blends several components of day trading, with the speed of position trading. Swing trading indicators are primarily used to find trends that play out between 3 and 15 trading periods. After we analyze these periods, we will be able to determine whether instances of resistance or support have occurred.
The common use of buying on margin (using borrowed funds) amplifies gains and losses, such that substantial losses or gains can occur in a very short period of time. In addition, brokers usually allow bigger margin for day traders. In the United States for example, while the initial margin required to hold a stock position overnight are 50% of the stock's value due to Regulation T, many brokers allow pattern day trader accounts to use levels as low as 25% for intraday purchases. This means a day trader with the legal minimum $25,000 in his account can buy $100,000 (4x leverage) worth of stock during the day, as long as half of those positions are exited before the market close. Because of the high risk of margin use, and of other day trading practices, a day trader will often have to exit a losing position very quickly, in order to prevent a greater, unacceptable loss, or even a disastrous loss, much larger than her original investment, or even larger than her total assets.
Much research on historical data has proven that, in a market conducive to swing trading, liquid stocks tend to trade above and below a baseline value, which is portrayed on a chart with an EM). In his book, "Come Into My Trading Room: A Complete Guide to Trading" (2002), Dr. Alexander Elder uses his understanding of a stock's behavior above and below the baseline to describe the swing trader's strategy of "buying normalcy and selling mania" or "shorting normalcy and covering depression." Once the swing trader has used the EMA to identify the typical baseline on the stock chart, he or she goes long at the baseline when the stock is heading up and short at the baseline when the stock is on its way down.
Swing, or range, trading Traders find a stock that tends to bounce around between a low and a high price, called a "range bound" stock, and they buy when it nears the low and sell when it nears the high. They may also sell short when the stock reaches the high point, trying to profit as the stock falls to the low and then close out the short position.

Spread trading This high-speed technique tries to profit on temporary changes in sentiment, exploiting the difference in the bid-ask price for a stock, also called a spread. For example, if a buyer’s bid price drops suddenly, the day trader might step in to buy and then try to quickly resell at the stock’s ask price or higher, earning a small “spread” on the transaction.
Disclaimer: Trading carries a high level of risk, and may not be suitable for all investors. Before deciding to invest you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with foreign exchange trading, and seek advice from an independent financial advisor if you have any doubts.

Swing traders should select their candidates from the most actively traded stocks and ETFs that show a tendency to swing within broad well-defined channels. Virtually all trading platforms provide a function to enter channel lines on a price chart. The trader should keep a list of stocks and ETFs to monitor on a daily basis and become familiar with the price action of their selected candidates.
The first type of scalping is referred to as "market making," whereby a scalper tries to capitalize on the spread by simultaneously posting a bid and an offer for a specific stock. Obviously, this strategy can succeed only on mostly immobile stocks that trade big volumes without any real price changes. This kind of scalping is immensely hard to do successfully, as a trader must compete with market makers for the shares on both bids and offers. Also, the profit is so small that any stock movement against the trader's position warrants a loss exceeding his or her original profit target.

The volume indicator could be interpreted as the “fuel tank of the major trading machine.” Some argue that the volume indicator cannot be used with trading in the forex market. This is because there is no “central exchange” so how can it be read effectively? Another argument is that the volume that you see for Forex is the “Tick” volume that occurs. This means you are not seeing the entire volume that is being traded at the time like you would with stocks.

Scalping is the shortest time frame in trading and it exploits small changes in currency prices.[1] 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.

Day traders are attuned to events that cause short-term market moves. Trading the news is a popular technique. Scheduled announcements such as economic statistics, corporate earnings or interest rates are subject to market expectations and market psychology. Markets react when those expectations are not met or are exceeded, usually with sudden, significant moves, which can benefit day traders.
