Day trading
From Wikipedia, the free encyclopedia
Day trading refers to the practice of buying and selling financial instruments within the same trading day such that all positions will usually (not necessarily always) be closed before the market close of the trading day. Traders that participate in day trading are called day traders.
Some of the more commonly day-traded financial instruments are stocks, stock options, currencies, and a host of futures contracts such as equity index futures, interest rate futures, and commodity futures.
Day trading used to be the preserve of financial firms and professional investors and speculators. Many day traders are bank or investment firms employees working as specialists in equity investment and fund management. However, day trading has become increasingly popular among casual traders due to advances in technology, changes in legislation, and the popularity of the Internet.

[edit] Characteristics
[edit] Trade Frequency
Although collectively called day trading, there are many sub-trading styles within day trading. A day trader is not necessarily very active. Depending on one's trading strategy, the number of trades made in a day may vary from a few to hundreds.
Some day traders focus on very short or short-term trading, in which a trade may last seconds to a few minutes. They buy and sell many times in a day, trading very high volumes daily and therefore receiving big discounts from the brokerage.
Some day traders focus only on momenta or trends. They are more patient and wait for a ride on the strong move which may occur on that day. They make far fewer trades than the aforementioned traders.
[edit] Overnight Position
Traditionally it is suggested day traders should always settle their positions before the market close of the trading day to avoid the risk of price gaps (differences between the previous day's close and the next day's open price) at the open. Some day traders consider this to be a golden rule to be obeyed at all times. Some day traders, however, believe they should let the profits run, so it is acceptable to stay with a position after the market closes.[1]
Day traders often borrow money to trade. Since margin interests are typically only charged on overnight balances, the extra costs discourage them from holding positions overnight.
[edit] Profit and Risks
Due to the nature of financial leverage and the rapid returns that are possible, day trading can be extremely profitable, and high-risk profile traders can generate huge percentage returns. Some day traders manage to earn millions per year solely by day trading.[2]
Due to the high profits (and losses) that day trading makes possible, these traders are sometimes portrayed as "bandits" or "gamblers" by other investors. Some individuals, however, make a consistent living day trading.[3]
Nevertheless day trading can become very risky, especially if one has poor discipline, risk or money management.[4] 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 margins for daytraders. Where overnight margins required to hold a stock position are normally 50% of the stock's value, 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 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 his original investment, or even larger than his total assets.
Even when a position has made a profit, the trader has to offset the transaction costs and the interest on the margin. It is commonly stated that 80-90% of day traders lose money. An analysis of the Taiwanese stock market suggests that "less than 20% of day traders earn profits net of transaction costs".[5]
[edit] History
Originally, the most important U.S. stocks were traded on the New York Stock Exchange. A trader would contact a stockbroker, who would relay the order to a specialist on the floor of the NYSE. These specialists would each make markets in only a handful of stocks. The specialist would match the purchaser with another broker's seller; write up physical tickets that, once processed, would effectively transfer the stock; and relay the information back to both brokers. Brokerage commissions were fixed at 1% of the amount of the trade, i.e. to purchase $10,000 worth of stock cost the buyer $100 in commissions.
One of the first steps to make day trading of shares potentially profitable was the change in the commission scheme. In 1975, the Securities and Exchange Commission made fixed commissions illegal, giving rise to discount brokers offering much reduced commission rates.
[edit] Financial Settlement
Financial settlement periods used to be much longer: Before the early 1990s at the London Stock Exchange, for example, stock could be paid for up to 10 working days after it was bought, allowing traders to buy (or sell) shares at the beginning of a settlement period only to sell (or buy) them before the end of the period hoping for a rise (or fall) in price. This activity was identical to modern day trading, but for the longer duration of the settlement period. Nowadays, to reduce market risk, the settlement period is typically three working days. Reducing the settlement period reduces the likelihood of default, but was impossible before the advent of electronic ownership transfer.
[edit] Electronic Communication Networks
The systems by which stocks are traded have also evolved, the second half of the twentieth century having seen the advent of Electronic Communication Networks (ECNs). These are essentially large proprietary computer networks on which brokers could list a certain amount of securities to sell at a certain price (the asking price or "ask") or offer to buy a certain amount of securities at a certain price (the "bid"). The first of these was Instinet. Instinet or "inet" (ECNs and exchanges are usually known to traders by a three- or four-letter designators, which identify the ECN or exchange on Level II stock screens) was founded in 1969 as a way for major institutions to bypass the increasingly cumbersome and expensive NYSE, also allowing them to trade during hours when the exchanges were closed. Early ECNs such as Instinet were very unfriendly to small investors, because they tended to give large institutions better prices than were available to the public. This resulted in a fragmented and sometimes illiquid market.
The next important step in facilitating day trading was the founding in 1971 of NASDAQ -- a virtual stock exchange on which orders were transmitted electronically. Moving from paper share certificates and written share registers to "dematerialized" shares, computerized trading and registration required not only extensive changes to legislation but also the development of the necessary technology: online and real time systems rather than batch; electronic communications rather than the postal service, telex or the physical shipment of computer tapes, and the development of secure cryptographic algorithms.
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". It is of no importance to the market-maker whether the price of a stock goes up or down, as it has enough stock and capital to constantly buy for less than it sells. 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 ECNs 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).
[edit] Technology Bubble (1997–2000)
In 1997, the SEC adopted "Order Handling Rules" which required market-makers to publish their best bid and ask on the NASDAQ. Another reform made during this period 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 MM's listed bid or ask. A defect in the system gave rise to arbitrage by a small group of traders known as the "SOES bandits", who made fortunes buying and selling small orders to market makers. The existing ECNs began to offer their services to small investors. New brokerage firms which specialized in serving online traders who wanted to trade on the ECNs emerged. New ECNs also arose, most importantly Archipelago (arca) and Island (isld). Archipelago eventually became a stock exchange and in 2005 was purchased by the NYSE (At this time, the NYSE has proposed merging Archipelago with itself, although some resistance has arisen from NYSE members). Commissions plummeted: in an extreme example (1000 shares of Google), in 2005 an online trader might buy $300,000 of stock at a commission of about $10, as opposed to the $3,000 commission he would have paid in 1974. Moreover, the trader would be able to buy the stock almost instantly and would get it at a cheaper price.
ECNs are in constant flux. New ones are formed, while existing ones are bought or merge. As of the end of 2006, the most important ECNs to the individual trader are Instinet (which bought Island in 2005), Archipelago (although technically it is now an exchange rather than an ECN), and The Brass Utility ("brut"), as well as the SuperDot electronic system now used by the NYSE.
This combination of factors has made day trading in stocks and stock derivatives (such as ETFs) possible. The low commission rates allow an individual or small firm to make a large numbers of trades during a single day. The liquidity and small spreads provided by ECNs allow an individual to make near-instantaneous trades and to get favorable pricing. High-volume issues such as Intel or Microsoft generally have a spread of only $0.01, so the price only needs to move a few pennies for the trader to cover his commission costs and show a profit.
The ability for individuals to day trade coincided with the extreme bull market in technical 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.
Adding to the day-trading frenzy were the enormous profits made by the "SOES bandits". (Unlike the new day traders, these individuals were highly-experienced professional traders able to exploit the arbitrage opportunity created by SOES.)
In March, 2000, this bubble burst, and a large number of less-experienced day traders began to lose money as fast, or faster, than they had made during the buying frenzy. The NASDAQ crashed from 5000 back to 1200; many of the less-experienced traders went broke, although a small minority of traders made fortunes shorting the market all the way down[citation needed].
[edit] Techniques
The following are several basic strategies by which day traders attempt to make profits. Besides these, some day traders also use contrarian (reverse) strategies (more commonly seen in algorithmic trading) to trade specifically against irrational behavior from day traders using these approaches.
Some of these approaches require shorting stocks instead of buying them normally: the trader borrows stock from his broker and sells the borrowed stock, hoping that the price will fall and he will be able to purchase the shares at a lower price. There are several technical problems with short sales - the broker may not have shares to lend in a specific issue, some short sales can only be made if the stock price or bid has just risen (known as an "uptick"), and the broker can call for the return of its shares at any time. Some of these restrictions (in particular the uptick rule) don't apply to trades of stocks that are actually shares of an exchange-traded fund (ETF).
[edit] Trend following
Trend following, a strategy used in all trading time frames, assumes that financial instruments which have been rising steadily will continue to rise, and vice versa. The trend follower buys an instrument which has been rising, or short-sells a falling one, in the expectation that the trend will continue.
[edit] Range trading
A range trader watches a stock that has been rising off a support price and 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. 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.
[edit] Scalping
Scalping originally referred to spread trading. Scalping is a trading style where small price gaps created by the bid-ask spread are exploited. It normally involves establishing and liquidating a position quickly, usually within minutes or even seconds.
Scalping highly liquid instruments for off the floor daytraders involves taking quick profits while minimizing risk (loss exposure). It applies technical analysis concepts such as over/under-bought, support and resistance zones as well as trendline, trading channel to enter the market at key points and take quick profits from small moves. The basic idea of scalping is to exploit the inefficiency of the market when volatility increases and the trading range expands.
[edit] Rebate Trading
Rebate Trading is an equity trading style that uses ECN rebates as a primary source of profit and revenue, considering the payment structure of ECN paying per share. Traders maximize their returns by trading low priced, high volume stocks. This enables them to trade more shares and have more liquidity with a set amount of capital.
[edit] News Playing
Playing news is primarily the realm of the day trader. The basic strategy 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. The most common cause for this is when rumors or estimates of the event (like those issued by market and industry analysts) were already circulated before the official release, and prices have already moved in anticipation. The news is said to be already in the stock price.
[edit] Cost
[edit] Trading Equipment
Some day trading strategies (including scalping and arbitrage) require relatively sophisticated trading systems and software. Many day traders use multiple monitors or even multiple computers to execute their orders.
A fast Internet connection, such as broadband, is essential for day trading.
[edit] Brokerage
Day traders do not use retail brokers, slow to execute trades, and with higher commissions than direct access brokers, who allow the trader to send their orders directly to the ECNs instead of indirectly through brokers. Direct access trading offers substantial improvements in transaction speed and will usually result in better trade execution prices (reducing the costs of trading).
[edit] Commission
Commissions for direct-access brokers are calculated based on volume. The more one trades, the cheaper the commission is. Where a retail broker might charge $10 or more per trade regardless of size, a typical direct-access broker can charge as cheap as $0.004 per share traded, or $0.25 per futures contract. A scalper can cover that cost with even a minimal gain.
As for the calculation method, some use pro-rata to calculate commissions and charges, where each tier of volumes charge different commissions. Other brokers use a flat-rate, where all commissions charges are based on which volume threshold one reaches.
[edit] Spread
The numerical difference between the bid and ask prices is referred to as the spread between them. Most worldwide markets operate on a Bid and ask based system.
The ask prices are immediate execution (market) prices for quick buyers (ask takers); bid prices for quick sellers (bid takers). If a trade is executed at market prices, closing that trade immediately without queuing would not get you back the amount paid because of the bid/ask difference.
Spread is 2 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.
[edit] Market Data
Real-time market data is necessary for day traders, rather than using the delayed (by anything from 10 to 60 minutes, per exchange rules[6]) market data that is available for free. 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.
[edit] Regulations and restrictions
Day trading is considered a risky trading style, and regulations require brokerage firms to ask whether the clients understand the risks of day trading and whether they have prior trading experience before entering the market.
[edit] Pattern day trader
In addition, NASD and SEC further restrict the entry by means of "pattern day trader" amendments. Pattern day trader is a term defined by the Securities and Exchange Commission to describe any trader who buys and sells a particular security in the same trading day (day trades), and does this four or more times in any five consecutive business day period. A pattern day trader is subject to special rules. The main rule being that in order to engage in pattern day trading the trader must maintain an equity balance of at least $25,000 in a margin account.[7]
