Glossary Technicals terminology
Accumulation A situation in which the market is dominated by buyers, who ýaccumulateý the commodity they are trading.
Andrew's Pitchfork Three parallel trendlines are drawn linking a major low or high with a point either side of this marking an intermediate high or low. The lines are extended to generate support/ resistance levels. The lines look a bit like the prongs of a pitchfork, hence the indicatorýs name.
Bollinger bands A system based on the premise that prices revert to their mean. The standard deviation of the moves away from the mean are used to form two bands around the price. Whenever the price breaks below or above the band, it is deemed too extreme a move and therefore liable to correct back from the standard deviation towards the mean of the price.
Breakout A sudden breakout of prices from a chart pattern that has been forming for some time. It marks the end of a period of uncertainty. The breakout point can often be used to guess how far prices will go in that direction.
Candlesticks A Japanese charting system which maps the open- high-low-and close of periodic price movements. A box is drawn around the open and close, and painted white if the close is above the open, and black if the close is below the open. The boxes and their little heads and tails look like candles and their wicks. Candlestick studies are full of exotic terms like Morning Star and Dark Cloud Cover; these describe how the black and white candles look, and can be interpreted as buy or sell signals.
Channel Like it sounds, a channel in which prices are moving. Parallel trendlines are drawn along the lows and highs of a price chart, forming a channel in which prices move. The trendlines form areas of support and resistance. Depending on the trend, the channel can be a downchannel or an upchannel.
Commodity Channel Index CCI measures the variation of an instrument's price from its mean. High / low values indicate that prices have moved too far from their mean. The usual range is +/1 100 and anything outside this is overbought or oversold.
Congestion When prices trade at similar levels over a period, the chart becomes cluttered with business at these levels and is referred to as 'congested'. Congestion areas are often seen as providing support/resistance. They are the levels at which, rather than breaking into new ground, prices tend to bog down and become trapped.
Consolidation All this means is that prices are moving in a broadly sideways range after a sharp move in one direction. If the prices have risen sharply, the gains are ýconsolidatedý, often for several days after the major move.
Cycles Cycle theory is based on the premise that prices are affected by an underlying cycle. Some of these are well known: the 54-year Kondratieff Wave economic cycle. Others are less obvious. Commodity indexes are affected by a 10 1/2 month futures cycle (individual commodities do not necessarily follow this).
Distribution Market is dominated by sellers, who are holding length and ýdistributingý to the players who need to buy.
Double bottom A bullish reversal pattern characterized by two lows at roughly equal value.
Double top A bearish reversal pattern characterized by two highs at roughly equal value.
Dow theory Theory of market movement developed by Charles Dow that prices move in defined trends of successive higher peaks and higher troughs in an uptrend, and lower peaks and lower troughs in a downtrend. Dow divides trends into primary, secondary and minor. Volume patterns are associated with specific points in a trend. Dow theory is the foundation of most modern technical theory.
Downtrend a price pattern characterized by subsequent falling highs and falling lows
Elliott Wave a theory developed by Ralph Elliott that prices move in a main five-wave trend followed by a corrective three- wave trend, the extent and scope of which are governed by certain commonly seen ratios (see Fibonacci)
Exponentially-smoothed moving average An average calculated using a system where a percentage of today's price is applied to yesterday's moving average value. eg. 9% MA =(today's close*9%)+(ydy's close*91%).
Fibonacci levels Commonly observed ratios between the size of a main trend and retracements. The main ratios are 38.2%, 50%, 61.8%, 100% and 161.8%. These ratios are derived from the number series named after the Italian mathematician: 1,1,2,3,5,8,13, 21... If the first term is divided by the one to the right of it, the result gets nearer and nearer to 0.618, a ratio that recurs in nature and art. Fibonacci levels are used in the weird and wonderful Elliott Wave Theory.
Flag A price chart pattern that looks like a flag-pole with a rectangular ýflagý hanging off it. It is often seen as a sign that the trend is likely to continue after a brief consolidation.
Gann theory An eclectic blend of fact and fantasy, the works of WD Gann caught on in the City in the late 1980s. Their chief virtue seems to be that they are understood by no-one, and so almost anyone can claim to be an expert in them without recourse.
Head and shoulders A reversal pattern characterized by a high, a higher high, a lower high, and a break below the line joining the lows between the highs, the so-called neck-line.
Inverse head and shoulders A bullish reversal pattern characterized by a low, a lower low, a less low low, and a breakout to the upside.
MACD (moving average convergence divergence) A trend following momentum indicator that maps the difference between two exponential moving averages, the 26 and 12-day. A nine-day exponential moving average is plotted on top of this as a 'signal' line to show buy/sell opportunities.
Momentum The simple difference between the price now and the price N days ago. Momentum is negative if the price now is below the price N days ago, and positive if it is above.
Moving average The mean of prices over a pre-defined period, for instance, the previous five days. The moving average for different time periods can be charted to generate short- and medium-term buy/sell signals. For instance, funds have in the past tended to buy when the price crosses the 40-day moving average from below, and to sell when it cuts the average from above.
Moving average crossover The point where a short moving average crosses a longer-moving average. These are often taken as buy or sell signals. When the shorter MA crosses the longer from below and both are turning upward, it is called a Golden Cross, a strong buy signal.
Moving average envelopes Envelopes use moving averages which are sifted up or down by a certain percentage to establish a certain 'normal' band in which the price moves. If prices break out of these, they tend to revert to the mean.
On Balance Volume OBV is a momentum indicator relating volume to price change. If prices rise, volume is considered up-volume; if price, it is considered down-volume. Up-volume is added to the cumulative total, and down-volume is subtracted.
Open interest Open interest is the number of open contracts on a given future or options contract. Longs or shorts that have not been closed out are OI. Short-covering/profit-taking will tend to reduce OI.
Optimization A technique used by technical analysts to decide on which measures work best in their specific markets. For instance, the 40-day moving average might generate good signals for oil and commodity markets, but not foreign exchange markets. BY using optimization software, traders hope to work out which measures work well for their specific instruments.
Oscillator The difference between two indicators. For instance, a moving average oscillator would reflect the difference between two moving averages. The oscillator ranges around a single line.
Pennants A price chart pattern that looks like a vertical line with a small triangle at the top. It is seen as a sign that a trend will continue after a brief consolidation.
Point-and-figure A charting system, which ignores time and displays only the main price changes. They comprise alternate columns of 0s(falls) and Xs (gains). Parameters used are box-size and reversal size.
Puts/calls ratio The ratio of puts to calls in an options market.
Random walk Theory that market prices move randomly around a main trend, in other words, that the volatility is arbitrary.
Rate of Change of Prices This is a simple momentum-type indicator. It is the simple momentum over n days divided by the price n days ago.
Relative strength index This has become one of the most widely used and popular of technical indicators. It was invented by Welles-Wilder, and uses a simple equation comparing the average up moves in the market to the average downmoves to give a single RSI number for a certain period. The 14-day RSI is widely used. RSIs of 20-30% tend to indicate the market is oversold, while those of 70-80% indicate it is overbought.
Resistance a price at which sellers are likely to enter the market in an uptrend
Retracement A temporary move in the opposite direction to that of the main trend. These are often
Spread Buying one instrument/commodity and selling another, with a view to profiting from the change in the gap between the two markets.
Stochastics The theory of stochastics is based on the premise that prices close nearer the high in an uptrend, and nearer the low in a downtrend. %D Slow %D %K %R are all just names for different ways of smoothing the stochastic measures derived from the uptrend/downtrend theory.
Support a price at which buyers are likely to start buying in a downtrend
Trend The trend is your friend. A trend at its most basic consists of a situation in which prices move more in one direction than another. Many technical measures attempt to discern when a price is moving in a trend, punctuated by minor corrections, and when it is simply trendless.
Trend lines Lines drawn on a price chart linking subsequent lows in a downtrend and subsequent highs in an uptrend.
Triangle Chart pattern. Prices trade sideways after a main trend, and the range gets smaller each day.
Triple bottom A bullish reversal pattern characterized by three highs at roughly equal value.
Triple top A bearish reversal pattern characterized by three highs at roughly equal value.
Uptrend a price pattern characterized by subsequent rising highs and rising lows
Volatility (Chaikin's) Calculate the exponential moving average of the difference between the daily high and low, let's call this 'range'. Volatility = range now <<minus>> range n days ago / range n day's ago..
Weighted moving average The average of prices over a certain period, but weighted to give more importance to the latest price. So, if it were a 5-day MA, the latest price might be weighted by a factor of 5, yesterday's by a factor of 4, the day before by 3 times, the day before twice, and before that, the simple price. Different weighting systems can be used.
