On-balance Volume
On-balance volume (OBV) is a technical analysis indicator intended to relate price and volume in the stock market. OBV is based on a cumulative total volume. The formula : OBV = OBV_ + \left\{ \begin{matrix} volume & \mathrm{if}\ close > close_{prev} \\ 0 & \mathrm{if}\ close = close_{prev} \\ -volume & \mathrm{if}\ close < close_{prev} \end{matrix} \right. Because OBV is a cumulative result, the value of OBV depends upon the starting point of the calculation.


Application

Total for each day is assigned a positive or negative value depending on prices being higher or lower that day. A higher close results in the volume for that day to get a positive value, while a lower close results in negative value. So, when prices are going up, OBV should be going up too, and when prices make a new rally high, then OBV should ...

Technical Analysis
In finance, technical analysis is an analysis methodology for analysing and forecasting the direction of prices through the study of past market data, primarily price and volume. Behavioral economics and quantitative analysis use many of the same tools of technical analysis, which, being an aspect of active management, stands in contradiction to much of modern portfolio theory. The efficacy of both technical and fundamental analysis is disputed by the efficient-market hypothesis, which states that stock market prices are essentially unpredictable, and research on whether technical analysis offers any benefit has produced mixed results. History The principles of technical analysis are derived from hundreds of years of financial market data. Some aspects of technical analysis began to appear in Amsterdam-based merchant Joseph de la Vega's accounts of the Dutch financial markets in the 17th century. In Asia, technical analysis is said to be a method developed by Homma Munehisa duri ...

Stock Market
A stock market, equity market, or share market is the aggregation of buyers and sellers of stocks (also called shares), which represent ownership claims on businesses; these may include ''securities'' listed on a public stock exchange, as well as stock that is only traded privately, such as shares of private companies which are sold to investors through equity crowdfunding platforms. Investment is usually made with an investment strategy in mind. Size of the market The total market capitalization of all publicly traded securities worldwide rose from US$2.5 trillion in 1980 to US$93.7 trillion at the end of 2020. , there are 60 stock exchanges in the world. Of these, there are 16 exchanges with a market capitalization of $1 trillion or more, and they account for 87% of global market capitalization. Apart from the Australian Securities Exchange, these 16 exchanges are all in North America, Europe, or Asia. By country, the largest stock markets as of January 2022 are in th ...

Volume (finance)
In capital markets, volume, or trading volume, is the amount (total number) of a security (or a given set of securities, or an entire market) that was traded during a given period of time. In the context of a single stock trading on a stock exchange, the volume is commonly reported as the number of shares that changed hands during a given day. The transactions are measured on stocks, bonds, options contracts, futures contracts and commodities. The average volume of a security over a longer period of time is the total amount traded in that period, divided by the length of the period. Therefore, the unit of measurement for average volume is shares per unit of time, typically per trading day. Significance Trading volume is usually higher when the price of a security is changing. News about a company's financial status, products, or plans, whether positive or negative, will usually result in a temporary increase in the trade volume of its stock. Shifts in trade volume can make obse ...

Divergence
In vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point. As an example, consider air as it is heated or cooled. The velocity of the air at each point defines a vector field. While air is heated in a region, it expands in all directions, and thus the velocity field points outward from that region. The divergence of the velocity field in that region would thus have a positive value. While the air is cooled and thus contracting, the divergence of the velocity has a negative value. Physical interpretation of divergence In physical terms, the divergence of a vector field is the extent to which the vector field flux behaves like a source at a given point. It is a local measure of its "outgoingness" – the extent to ...

Joseph Granville
Joseph Ensign Granville (August 20, 1923 – September 7, 2013), often called Joe Granville, was a financial writer and investment seminar speaker. He is most famous for inventing and developing the concept of "On-balance volume (OBV)". Granville argued that when volume increases sharply without a significant change in a stock's price, the price will eventually increase rapidly, and vice versa. On balance volume is thus one tool of technical analysis that attempts to predict future prices of stocks, commodities, and other financial assets traded on financial markets for which historical price and volume information is available. Granville published a popular financial newsletter called The Granville Market Letter from 1963 until shortly before his death in 2013, appeared frequently on television programs such as CNBC, and gave seminars nationwide.Nikolaj Gammeltoft, Bloomberg, September 9, 201Joe Granville, Whose Bearish Calls Moved Stocks, Dies at 90/ref> Granville is probably ...

Prentice Hall
Prentice Hall was an American major educational publisher owned by Savvas Learning Company. Prentice Hall publishes print and digital content for the 6–12 and higher-education market, and distributes its technical titles through the Safari Books Online e-reference service. History On October 13, 1913, law professor Charles Gerstenberg and his student Richard Ettinger founded Prentice Hall. Gerstenberg and Ettinger took their mothers' maiden names, Prentice and Hall, to name their new company. Prentice Hall became known as a publisher of trade books by authors such as Norman Vincent Peale; elementary, secondary, and college textbooks; loose-leaf information services; and professional books. Prentice Hall acquired the training provider Deltak in 1979. Prentice Hall was acquired by Gulf+Western in 1984, and became part of that company's publishing division Simon & Schuster. S&S sold several Prentice Hall subsidiaries: Deltak and Resource Systems were sold to National Education ...

Money Flow
The money flow index (MFI) is an oscillator that ranges from 0 to 100. It is used to show the ''money flow'' (an approximation of the dollar value of a day's trading) over several days. The steps to calculate the money flow index over N days Step 1: Calculate the typical price The typical price for each day is the average of high price, the low price and the closing price. : typical\ price = Step 2: Calculate the positive and negative money flow The money flow for a certain day is typical price multiplied by volume on that day. : money\ flow = typical\ price \times volume The money flow is divided into positive and negative money flow. * Positive money flow is calculated by adding the money flow of all the days where the typical price is higher than the previous day's typical price. * Negative money flow is calculated by adding the money flow of all the days where the typical price is lower than the previous day's typical price. * If typical price is unchanged then tha ...

Price And Volume Trend
A price is the (usually not negative) quantity of payment or compensation given by one party to another in return for goods or services. In some situations, the price of production has a different name. If the product is a "good" in the commercial exchange, the payment for this product will likely be called its "price". However, if the product is "service", there will be other possible names for this product's name. For example, the graph on the bottom will show some situations A good's price is influenced by production costs, supply of the desired item, and demand for the product. A price may be determined by a monopolist or may be imposed on the firm by market conditions. Price can be quoted to currency, quantities of goods or vouchers. * In modern economies, prices are generally expressed in units of some form of currency. (More specifically, for raw materials they are expressed as currency per unit weight, e.g. euros per kilogram or Rands per KG.) * Although prices ...

Accumulation/distribution Index
The accumulation/distribution line or accumulation/distribution index in the stock market, is a technical analysis indicator intended to relate price and volume, which supposedly acts as a leading indicator of price movements. Formula : CLV = This ranges from -1 when the close is the low of the day, to +1 when it's the high. For instance if the close is 3/4 the way up the range then CLV is +0.5. The accumulation/distribution index adds up volume multiplied by the CLV factor, i.e. : accdist = accdist_ + volume \times CLV The starting point for the acc/dist total, i.e. the zero point, is arbitrary, only the shape of the resulting indicator is used, not the actual level of the total. The name accumulation/distribution comes from the idea that during accumulation buyers are in control and the price will be bid up through the day, or will make a recovery if sold down, in either case more often finishing near the day's high than the low. The opposite applies during distribution ...

Dimensional Analysis
In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric current) and units of measure (such as miles vs. kilometres, or pounds vs. kilograms) and tracking these dimensions as calculations or comparisons are performed. The conversion of units from one dimensional unit to another is often easier within the metric or the SI than in others, due to the regular 10-base in all units. ''Commensurable'' physical quantities are of the same kind and have the same dimension, and can be directly compared to each other, even if they are expressed in differing units of measure, e.g. yards and metres, pounds (mass) and kilograms, seconds and years. ''Incommensurable'' physical quantities are of different kinds and have different dimensions, and can not be directly compared to each other, no matter what units they are expressed in, e.g. metres and ...
