What is Ease of Movement?
The Ease of Movement (EMV) indicator measures the degree to which prices can be moved by a lower volume of trading. It was developed by Richard Arms, inventor of the Arms Index, which also attempts to quantify the relationship between price movements and volume. High positive values indicate a present tendency for prices to increase on low volume, and larger negative values indicate that prices are slipping lower but with relatively low trade volume. Continue reading...
What is Volume?
Volume is a count of trades in a security or market, or their derivative instruments and can be indicative of trends and sentiment. Volume is the number of trades in a security or market in a given time. Trade volume is important because it helps analysts pick apart the factors driving a trend or get an idea of the strength of a trend. Potential buyers and sellers can push the Bid and Ask prices around at will, hypothetically, but a trade only occurs when the buyer and seller transact business; also, even only a minimal number of trades can move prices around, but this is not indicative of a strong trend — a few trades more and the price is where it was before.

How to use Open Interest in trading
Open interest, or OI, can be a very important number for futures, options, and other derivative markets, but it can also be important to traders in the traditional stock market. Open interest in derivatives of stocks indicates that there is a deep market for the stock itself, since many of the positions may eventually require the purchase of the stock. Increases and decreases in open interest may help a trader understand if there's significant action in a security's price movements, which can determine liquidity needs as well as whether the price movements are rooted in actual supply and demand characteristics. Continue reading...
What is the Short Interest Ratio?
The Short Interest Ratio (SIR) measures investor sentiment for a given company and is calculated using the number of shares being shorted divided by the average daily trading volume of the stock. Also called the short ratio or float short, the SIR is a ratio of the number of shares being shorted divided by the average daily trading volume for the stock over the last 30 days. The ratio can be interpreted as the number of days it takes short sellers to repurchase borrowed shares, or an approximation for the number of shares that have been sold short and not yet covered as a percentage of all trading volume. Continue reading...
What is the Positive Volume Index?
The Positive Volume Index (PVI) is a technical indicator that tracks increases in trade volume for an index or security, as well as the changes in price on those days. Paul Dysart developed the original version of this indicator for market indexes using advance-decline numbers instead of prices. The Positive Volume Index was then redesigned by Norman Fosback for individual securities – the version commonly used today. Continue reading...
What is the Negative Volume Index?
The Negative Volume Index (NVI) is a technical indicator that tracks decreases in trade volume for an index or security, as well as price changes on those days. Paul Dysart developed the original version of this indicator for market indexes, and it garnered renewed attention when it was reworked in the 1970s via Norman Fosback in his book Stock Market Logic. The price changes in a security or the percentage change in an index are only added to or subtracted from the Negative Volume Index on days when the trading volume is lower than the day before. By watching market movement on days with lower trading volume, investors can identify where institutions and fund managers are moving their money. If trading volume is down and the market continues to do well, it means that there is a strong bullish primary trend, and that trading volume is not artificially pushing prices around. Continue reading...
How to use the On-Balance Volume in trading?
On-Balance Volume (OBV) is a popular leading indicator introduced in the 1960s by Joe Granville. OBV is a line built using differences between daily trading volume – in Granville’s estimation, the major driver of market behavior – adding the difference on days that the market or stock moves up and subtracting the difference on days when the market or stock moves down. It looks for instances of rising volume that should correlate with price movement, but price movement has not occurred; additionally, OBV can be used to confirm lag. Continue reading...
What is Volume Weighted Average Price (VWAP)?
The Volume Weighted Average Price (VWAP) helps traders consider the influence of volume on prices. VWAP is calculated by taking the average of prices from a time period and dividing it by the trading volume for the current day. Traders use VWAP to confirm trends and decide whether to take long or short positions, while large institutions are likely to use VWAP to avoid disrupting market prices, finding the liquid and illiquid price points and trading so as not to move prices away from the averages. Continue reading...
What are market indicators?
Market indicators are quantitative tools for the analysis of market information, which may hint or confirm that a trend or reversal is about to happen (leading indicator) or has begun (lagging indicator). Indicators are technical analysis algorithms which give investors signals that may be used as the guidelines for trading. Indicators might be called oscillators or have various other proper names, since some of them are quite well-known, but there are general conventions or instructions for how to use an indicator, how it can be tweaked to suit the scope of your analysis, and what is considered a trade signal. Continue reading...
What are Technical Indicators?
Technical Indicators are charting tools that appear as lines on charts, or as other kinds of graphical information, which serve as guidelines for buying and selling opportunities. They are based on mathematical formulas, and may be called oscillators, trading bands, and signal lines, among other things. Technical analysts use information about price, volume, standard deviation, and other metrics to construct systems for trading using mathematical formulas which can be translated into useful charting tools. The systems can bring discipline to a trader’s strategy by providing clearly defined circumstances in which a trader has reason to buy, sell, hold, and so on. Continue reading...
What is a leading indicator?
Leading indicators are economic or price data which have some degree of correlation with a movement in the market or a stock price. Leading indicators tend to happen before the market or price movement occurs. Traders and economists use leading indicators frequently to prepare for what’s next; they are based on theory as well as empirical historical evidence but like all indicators, they do not have a 100% accuracy rate – past performance does not guarantee future results. Continue reading...
What are the main technical indicators?
Technical indicators include moving average lines, trading bands, oscillators, and formations (found here), often presented in combinations. Popular indicators carry proper names. There are thousands of technical indicators, but the most popular ones are the MACD, Bollinger Bands, Stochastic Oscillators, the Directional Movement Indicator and various patterns of price behavior, such as “Head and Shoulder” formations. Continue reading...
What Kinds of Overlays are Used in Chart Patterns?
Overlays are technical supplements which help to interpret the data of a normal price chart. Often a chart program will allow the user to pick a few different overlays at a time, to help him or her get a better idea of what is going on with the price. Some common overlays include moving average lines, Bollinger Bands, Ichimoku clouds, and channel lines. An overlay or series of overlays will appear as additional lines, shading, or other graphics on a price chart. An overlay helps a trader or analyst interpret the price data in the context of other data, by putting the other data right on top of it. Continue reading...
What does open interest mean?
Open interest is a measurement of the outstanding open positions in a derivative security. Strong open interest means the derivative will have high liquidity. Open Interest is not the same thing as Trading Volume, but it does give an indication of liquidity and activity in a derivative. Open Interest is the number of open positions for a derivative, like an option. The Options Clearing Corporation tallies up the ‘open interest’ numbers, but they are not posted until the morning following the count. Open Interest isn't necessarily indicative of a bullish or bearish forecast for the underlying security, but it does generally mean that the option will have high liquidity and that a seller will be able to find a buyer. Continue reading...
How to use Momentum Indicators in trading
A momentum indicator allows for a quick comparison of a security’s current price relative to its past prices using a flexible time period, allowing traders to decide the parameters. The formula to calculate momentum is M = V – Vx (where V is the current price and Vx is the closing price from x number of days ago). A current price in excess of past price is a positive momentum indicator; a lower current price represents negative momentum. Continue reading...
How to use the Arms Index (TRIN) in trading
Richard Arms invented the analysis tool that bears his name in 1967. The Arms Index, a technical analysis indicator, is also called the TRIN (short for “Trading Index”) because it seeks to indicate overbought or oversold conditions by serving as an index of trading activity relative to price. The Arms index is calculated using readily available data from major indexes such as the S&P 500 or NASDAQ. The ratio of the number of advancing stocks (stocks whose prices are increasing) to the number of declining stocks (stocks whose prices are decreasing) is computed to give us the A/D Ratio, a market breadth indicator that is one way of viewing the daily breadth of a security. The Advance/Decline Ratio uses the same numbers as the Advance/Decline Line but presents them as a ratio instead. The AD Ratio is sometimes more useful than an AD Line, including in instances where comparing AD for different indexes which have different metrics; the ratio is the standardization with which comparisons can be made. Continue reading...
How to use the Accumulation/Distribution in trading
The Accumulation/Distribution Indicator (originally called the Cumulative Money Flow Line) tracks cash flow into or out of a security and correlates the cash flow changes to changes in the security price. By following the trading volume into or out of a security, it establishes the degree of correlation between this trading volume and the price of the security. Accumulation/distribution is designed to reveal divergences in price trends (specifically between stock price and trading volume). These divergences indicate the degree to which a security may be overbought or oversold at a given time. Continue reading...
What is a Market Order?
A market order is an order to execute a trade (buy or sell) immediately at whatever the current market price. If an investor places a market order after hours, for instance, the order will be filled at the market’s open wherever the price of the security is. Placing a market order, also known as an “unrestricted order,” means the person trading the security is more concerned with timely execution of the trade than they are the actual price. If a market order is placed for a security that has very high volumes and is a common stock, the market order is likely to be filled right away. Continue reading...
What is market breadth?
Market Breadth is a descriptor that is used in several market indicators such as the daily breadth, the A/D Line, the McClellan Oscillator, and Arms Index. Breadth is the relative difference in the amount of advancing stocks and declining stocks. Daily breadth is simply computed by subtracting one from the other, or creating a ratio in which one is divided by the other. Daily breadth is closely related, even interchangeable, with the Advance/Decline ratio. It can also refer to the difference between New Highs and New Lows, or Net New Highs. Continue reading...
What is market momentum?
Market momentum is the tendency of a trend to continue in one direction or another. Various analysis methods and indicators seek to identify the strength of trends and to find points of possible reversals and retracements. A market has strong momentum when trading volume is up and confirms the direction of price movement in the market. Bullish or bearish market sentiment will influence the degree of momentum that is present. Continue reading...
