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.
Market data is necessary for day traders to be competitive. A real-time data feed requires paying fees to the respective stock exchanges, usually combined with the broker's charges; these fees are usually very low compared to the other costs of trading. The fees may be waived for promotional purposes or for customers meeting a minimum monthly volume of trades. Even a moderately active day trader can expect to meet these requirements, making the basic data feed essentially "free". In addition to the raw market data, some traders purchase more advanced data feeds that include historical data and features such as scanning large numbers of stocks in the live market for unusual activity. Complicated analysis and charting software are other popular additions. These types of systems can cost from tens to hundreds of dollars per month to access.[19]
Day trading was once an activity that was exclusive to financial firms and professional speculators. Many day traders are bank or investment firm employees working as specialists in equity investment and fund management. Day trading gained popularity after the deregulation of commissions in the United States in 1975, the advent of electronic trading platforms in the 1990s, and with the stock price volatility during the dot-com bubble.[2]
Finally, keep in mind that if trading on margin—which means you're borrowing your investment funds from a brokerage firm (and bear in mind that margin requirements for day trading are high)—you're far more vulnerable to sharp price movements. Margin helps to amplify the trading results not just of profits, but of losses as well if a trade goes against you. Therefore, using stop losses is crucial when day trading on margin.

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.
Whether you are scalping EUR: USD, other currency pairs, or other assets outside of forex, it’s important to pay attention to the details. Scalping typically occurs in 5-20 minute increments. However, if you were trying to implement a one-minute scalping strategy, volume indicators, M5/M15 time charts, and price action trends should be the first things you look at.
The ability for individuals to day trade coincided with the extreme bull market in technological issues from 1997 to early 2000, known as the dot-com bubble. From 1997 to 2000, the NASDAQ rose from 1200 to 5000. Many naive investors with little market experience made huge profits buying these stocks in the morning and selling them in the afternoon, at 400% margin rates.
Following the 1987 stock market crash, the SEC adopted "Order Handling Rules" which required market makers to publish their best bid and ask on the NASDAQ.[7] Another reform made was the "Small-order execution system", or "SOES", which required market makers to buy or sell, immediately, small orders (up to 1000 shares) at the market maker's listed bid or ask. The design of the system gave rise to arbitrage by a small group of traders known as the "SOES bandits", who made sizable profits buying and selling small orders to market makers by anticipating price moves before they were reflected in the published inside bid/ask prices. The SOES system ultimately led to trading facilitated by software instead of market makers via ECNs.[8]
This part is all up to you. There is no "line crossing," "arrow appearing" or "a small voice telling you to buy now!" You have to understand a little bit about how the price action works before you decide on your entry. Using our example, the Volume indicator shot up drastically meaning that traders are getting in on the action and thus driving the price upwards!
There are a variety of methodologies to capitalize on market swings. Some traders prefer to trade after the market has confirmed a change of direction and trade with the developing momentum. Others may choose to enter the market on the long side after the market has dropped to the lower band of its price channel—in other words, buying short-term weakness and selling short-term strength. Both approaches can be profitable if implemented with skill and discipline over time.
Aside from a risk/reward, the trader could also utilize other exit methods, such as waiting for the price to make a new low. With this method, an exit signal wasn't given until $216.46, when the price dropped below the prior pullback low. This method would have resulted in a profit of $23.76 per share. Thought of another way: a 12% profit in exchange for less than 3% risk. This swing trade took approximately two months.

Many professional money managers and financial advisors shy away from day trading arguing that, in most cases, the reward does not justify the risk. Conversely, those who do day trade insist there is profit to be made. Day trading profitably is possible, but the success rate is inherently lower because of the complexity and necessary risk of day trading in conjunction with the related scams. Moreover, economists and financial practitioners alike argue that over long time periods, active trading strategies tend to underperform a more basic passive index strategy, especially after fees and taxes are taken into account.

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).
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 key to scalping while using short time frames is to identify price changes before the rest of the market has had the chance to act. You should also be willing to accept very low profit margins—gaining less than 1% on a given action will still usually be in your best interest. Because of this, many scalpers may implement tight stop-loss and stop-limit orders over time.  

Hi, You have really explained well about intraday trading strategy its best to use it intraday as the newsflow means no fundamental shifts to the market and relative stability in the underlying assumptions. Smart traders may wish to use the 15 minutes/1-hour candles to create these strategies. Lesser may mean transactions costs will eat into profits and higher may mean too much interference with underlying markets.

The problem most new traders make is that they don't practice a strategy in a demo account, for several months or more, before risking real capital. Therefore, they have no idea how a strategy works, and how they need to adjust it when market conditions change. The demo accounts serves as a testing ground, where new traders can test out ideas, see what works and hone trading psychological skills (such as patience, discipline and focus).
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.
