The most common type of distribution for a variable. The term "bell curve" comes from the fact that the graph used to depict a normal distribution consists of a bell-shaped line. The bell curve is also known as a normal distribution. The bell curve is less commonly referred to as a Gaussian distribution, after German mathematician and physicist Karl Gauss, who popularized the model in the scientific community by using it to analyze astronomical data. The highest point in the curve, or the top of the bell, represents the most probable event. All possible occurrences are equally distributed around the most probable event, which creates a downward-sloping line on each side of the peak.
A trend indicated by a large candlestick followed by a much smaller candlestick whith a that body is located within the vertical range of the larger candle's body. Such a pattern is an indication that the previous upward trend is coming to an end. A bearish harami may be formed from a combination of a large white or black candlestick and a smaller white or black candlestick. The smaller the second candlestick, the more likely the reversal. It is thought to be a strong sign that a trend is ending when a large white candle stick is followed by a small black candlestick.
A price movement through an identified level of support, which is usually followed by heavy volume and sharp declines. Technical traders will short sell the underlying asset when the price of the security breaks below a support level because it is a clear indication that the bears are in control and that additional selling pressure is likely to follow. Technical tools such as moving averages, trendlines and chart patterns are the most common methods for technical traders to identify strong areas of support. The chart above shows that a trader will enter into a short position when the price breaks below an area of support (the thick dark line), which has been identified by using a head and shoulders chart pattern.A breakdown is the bearish counterpart of a breakout.
A term used in technical analysis. A breakaway gap represents a gap in the movement of a stock price supported by levels of high volume. The image shows a gap at the beginning of a large upward movement. If you chart it, the gap reflects a bullish movement when the price has gapped upwards and a bearish movement when the price has gapped downwards.
A technical analysis theory that predicts the strength of the market according to the number of stocks that advance or decline in a particular trading day. The breadth of market indicator is used to gauge the number of stocks advancing and declining for the day. If the breadth indicator is strong, this theory predicts that the market will be rising and vice versa.
A specific type of indicator that uses advancing and declining issues to determine the amount of participation in the movement of the stock market. There are several different types of breadth indicators used by technical analysts.
A mathematical model designed to forecast data within a time series. The Box-Jenkin model alters the time series to make it stationary by using the differences between data points. This allows the model to pick out trends, typically using autoregresssion, moving averages and seasonal differencing in the calculations. Autoregressive Integrated Moving Average (ARIMA) models are a form of Box-Jenkins model. Estimations of the parameters of the Box-Jenkins model is very complicated and is most often achieved through the use of software. The model was created by two mathematicians, George Box and Gwilym Jenkins, and outlined in their 1970 paper, "Time Series Analysis: Forecasting and Control."
In the context of Point & Figure Charts, the box size is the minimum price change that must occur for a given period before a mark (an X or an O) is added to the chart. You can filter out smaller price movements by increasing the box size.
