Trading 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).
The Securities and Exchange Commission removed the uptick requirement for short sales on July 6, 2007.
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 with falling. The trend follower buys an instrument
which has been rising, or short-sells a falling one, in the expectation that the trend will continue.
Contrarian Investing: Contrarian investing is a market timing strategy used in all trading time-frames. It
assumes that financial instruments which have been rising steadily will reverse and start to fall, and vice versa
with falling. The contrarian trader buys an instrument which has been falling, or short-sells a rising one, in the
expectation that the trend will change.
Range Trading: Range 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.
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.
Scalping (Trading): 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 day traders 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.
