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.

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.
The sheer volume of forex trading makes it attractive for day traders. There are multiple short-term opportunities in a trending currency pair, and an unrivalled level of liquidity to ensure opening and closing trades is quick and slick. More suited to technical analysis, there are other ways to trade foreign exchange. In addition, forex has no central market. This means traders can make trades six days a week, 24 hours a day. They present a great starting point for entry level or aspiring traders with full time jobs. Traders in Australia might be specifically interested in trading the AUD USD pair.

Years ago, when stocks were quoted in fractions, there was a standard spread of 1/16 of a dollar or a "teenie". This spread allowed scalp traders to buy a stock at the bid and immediately sell at the ask. Hence the teenie presented clear entry and exit levels for scalp traders. The scalp trading game took a turn for the worst when the market converted to the decimal system. The decimal system closed the "teenie" often times to within 1 penny for high volume stocks. This overnight shifted the strategy for scalp traders. A scalp trader now had to rely more on their instincts, level II, and the time and sales window.
It is important to understand the fundamentals of intraday trading in order to make consistent profits. A good tip is to trade with the current market trend. If the market is falling, sell first and buy later, and vice versa. Make an intraday trade plan and stick to the plan. Set your desired profit and stop-loss limit. Do not be greedy. Instead, book your profits at regular intervals. Maintain stop-loss levels. It helps you to limit your loss if the market does not perform. Also, choose highly liquid shares and trade in a small number of shares at a time, if you are not a seasoned trader.
Range trading, or range-bound trading, is a trading style in which stocks are watched that have either been rising off a support price or falling off a resistance price. That is, every time the stock hits a high, it falls back to the low, and vice versa. Such a stock is said to be "trading in a range", which is the opposite of trending.[13] The range trader therefore buys the stock at or near the low price, and sells (and possibly short sells) at the high. A related approach to range trading is looking for moves outside of an established range, called a breakout (price moves up) or a breakdown (price moves down), and assume that once the range has been broken prices will continue in that direction for some time.
It needs sheer dedication, hard work, patience, quick wit and immense knowledge to be successful in intraday trading. Successful intraday trading involves 90% waiting and 10% execution. So, yes, it can make a trader rich in a relatively short period of time if the correct processes are followed, and yes, it is possible to hold on to the profits in the long-term if the correct strategies are followed.
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). 
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.
As with any other style of trading, many different methods of scalping exist. The most well-known scalping technique is using the market's time and sales to determine when and where to make trades. Scalping using the time and sales is sometimes referred to as tape reading because the time and sales used to be displayed on the old-fashioned ticker tape, known as the tape.

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.

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.
Day trading is defined as the purchase and sale of a security within a single trading day. It can occur in any marketplace but is most common in the foreign exchange (forex) and stock markets. Day traders are typically well-educated and well-funded. They use high amounts of leverage and short-term trading strategies to capitalize on small price movements in highly liquid stocks or currencies.
