These developments heralded the appearance of "market makers": the NASDAQ equivalent of a NYSE specialist. A market maker has an inventory of stocks to buy and sell, and simultaneously offers to buy and sell the same stock. Obviously, it will offer to sell stock at a higher price than the price at which it offers to buy. This difference is known as the "spread". The market maker is indifferent as to whether the stock goes up or down, it simply tries to constantly buy for less than it sells. A persistent trend in one direction will result in a loss for the market maker, but the strategy is overall positive (otherwise they would exit the business). Today there are about 500 firms who participate as market makers on ECNs, each generally making a market in four to forty different stocks. Without any legal obligations, market makers were free to offer smaller spreads on electronic communication networks than on the NASDAQ. A small investor might have to pay a $0.25 spread (e.g. he might have to pay $10.50 to buy a share of stock but could only get $10.25 for selling it), while an institution would only pay a $0.05 spread (buying at $10.40 and selling at $10.35).
Commissions for direct-access brokers are calculated based on volume. The more shares traded, the cheaper the commission. The average commission per trade is roughly $5 per round trip (getting in and out of a position). While a retail broker might charge $7 or more per trade regardless of the trade size, a typical direct-access broker may charge anywhere from $0.01 to $0.0002 per share traded (from $10 down to $.20 per 1000 shares), or $0.25 per futures contract. A scalper can cover such costs with even a minimal gain.
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.

To offset this, day traders are often offered the "opportunity" to leverage their portfolios with more margin, four times the buying power rather than double. Taking larger leveraged positions can increase percentage gains to offset costs. The problem is that no one is right all the time. A lack of focus, discipline, or just plain bad luck can lead to a trade that goes against you in a big way. A bad trade, or string of bad trades, can blow up your account, where the loss to the portfolio is so great the chances of recovery are slim. For a swing trader, a string of losses or a big loss can still have a dramatic effect, but the lower leverage reduces the likelihood that the results wipe out your portfolio.
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.
Scalping can be very profitable for traders who decide to use it as a primary strategy, or even those who use it to supplement other types of trading. Adhering to the strict exit strategy is the key to making small profits compound into large gains. The brief amount of market exposure and the frequency of small moves are key attributes that are the reasons why this strategy is popular among many types of traders.

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.
The first EMA (50) should be positioned below the second EMA (100). As with the buy entry points, we wait until the price returns to the EMAs. Additionally, the Stochastic Oscillator is utilised to cross over the 80 level from above. As soon as all the items are in place, you may open a short or sell order without any hesitation. The exact same things occur here. Stop-losses are positioned near 2-3 pips above the last high point of the swing accordingly, and take-profits should remain within 8-12 pips from the entry price.
The following are several basic trading strategies by which day traders attempt to make profits. In addition, some day traders also use contrarian investing strategies (more commonly seen in algorithmic trading) to trade specifically against irrational behavior from day traders using the approaches below. It is important for a trader to remain flexible and adjust techniques to match changing market conditions.[11]

It is estimated that more than 75% of stock trades in United States are generated by algorithmic trading or high-frequency trading. The increased use of algorithms and quantitative techniques has led to more competition and smaller profits.[17] Algorithmic trading is used by banks and hedge funds as well as retail traders. Retail traders can choose to buy a commercially available Automated trading systems or to develop their own automatic trading software.
Software and gimmicky products that promise riches overnight typically have a very short shelf life. They may work for a little while, but ultimately they will fail you unless you know how to make adjustments to the software yourself. Instead of getting suckered into trading product scams you're much better off spending your time and money on your own education.
The bid–ask spread is two sides of the same coin. The spread can be viewed as trading bonuses or costs according to different parties and different strategies. On one hand, traders who do NOT wish to queue their order, instead paying the market price, pay the spreads (costs). On the other hand, traders who wish to queue and wait for execution receive the spreads (bonuses). Some day trading strategies attempt to capture the spread as additional, or even the only, profits for successful trades.[18]
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.

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.
