Day traders use only risk capital which they can afford to lose. Not only does this protect them from financial ruin, but it also helps eliminate emotion from their trading. A large amount of capital is often necessary to capitalize effectively on intraday price movements. Having access to a margin account is also key, since volatile swings can incur margin calls on short notice.
Day trading is traditionally defined as buying and selling stock, options, or commodities during the same trading day and be have your positions closed by the end of the trading session. In the past, day trading had been reserved for financial companies and professional investors. A large percentage of day traders work for investment firms or are specialists in fund management. With the advance of technology, day trading has continue to grow among the casual trader working from home.
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. 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.
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.
A trader can measure their performance as a percentage of the trading channel width. The perfect trade would be buying at the bottom channel line and selling at the top channel line, which would be a 100% performance. If a trader captured one-half of the channel, it would be a 50% performance. The goal is to continually increase the performance percentage of the average winning trade.
The intraday trading strategy to be used also depends upon the traders’ personal trading styles, along with being dependent on the market conditions. Some traders are very active and do many trades a day, with large position sizes, catching even the small price movements; while there are others who trade only on specific news events or only on tendencies that they have well researched.
In addition, in the United States, the Financial Industry Regulatory Authority and SEC further restrict the entry by means of "pattern day trader" amendments. Pattern day trader is a term defined by the SEC 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 in a margin account, the trader must maintain an equity balance of at least $25,000. It is important to note that this requirement is only for day traders using a margin account.
In addition to knowledge of basic trading procedures, day traders need to keep up on the latest stock market news and events that affect stocks—the Fed's interest rate plans, the economic outlook, etc. So do your homework. Make a wish list of stocks you'd like to trade and keep yourself informed about the selected companies and general markets. Scan business news and visit reliable financial websites.
