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...
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.

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 is a resistance line?
A resistance line is the inverse of a support line and represents the glass ceiling through which a security price has difficulty breaking through. Resistance lines are calculated as part of analysis methods which use moving averages and standard deviation, or similar calculations, to put a range of probability on the expected movement of a security price, with the resistance line representing the top of that range. 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...
How to use the Aroon Indicators in trading?
The Aroon Indicators are a pair of momentum indicators – the Aroon Up value and Aroon Down value – named after the Sanskrit word for the first light of day. Each indicator represents a standardized value for the strength of the upward or downward pressure on a stock, which analysts can compare to determine if there is a trend emerging. Aroon looks at the latency between highs for certain rolling time periods, with 25 days being the standard time frame. Continue reading...
What are Envelopes and Trading Bands?
Moving average envelopes and trading bands help traders filter their decisions to trade. These tools set thresholds on the amount of movement above and below a moving average to trigger a decision to trade (or at least prompt further consideration by the trader). A moving average envelope often takes a moving average line for a security or index and duplicates it, moving one line a certain percentage above and one a certain percentage below (the distance may depend on volatility levels). Price fluctuations in a security then might trigger a decision to sell when the price hits the upper band, or a decision buy when the price hits the lower band. If it crosses the bands it might be seen as a new trend. Continue reading...
What is adaptive price zone?
Adaptive Price Zone is a volatility-based trading indicator. Similar to traditional Bollinger Bands, Adaptive Price Zone is a recent development by Lee Leibfarth that overlays two indicator bands around a moving average line. It is more adaptive than many previous band indicators, using several short-term exponential moving averages which are double-smoothed and closely hug changes in volatility and price data. Exponential moving averages give more weight to recent data, which helps the lines hug current data. Continue reading...
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...
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...
How to use the Chaikin Oscillator in trading
The Chaikin Oscillator is a volume indicator that can help traders discern if price movements are verified by changes in trading volume. When there are discrepancies, it can mean that prices are exhibiting overbought or oversold conditions. Before the Chaikin Oscillator, On-Balance Volume was the most popular indicator for the job. 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 technical analysis in trading?
Technical analysis is a method of evaluating the worth and probable future direction of security prices using charts and data concerning prices and volume. This is the counterpart to fundamental analysis, which looks at the physical operations of a company and their place in the market to determine value. Those who practice technical analysis are sometimes called “quants” or chartists because they believe that the most important information about a security will be found in the data on the price, volume, and the moving averages and volatility associated with them. Continue reading...
What is the Absolute Breadth Index?
The Absolute Breadth Index (ABI) is a market breadth indicator, calculated using the absolute value of the difference between the number of advancing stocks and declining stocks to indicate the size of market movement without considering price direction. Larger ABI numbers will indicate more volatility. When breadth is smaller, it means that the market isn’t experiencing significant movement, or movement in a definitive direction. When advances or declines pull away from the other, it indicates the presence of market-wide trends. 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...
How to use the Advance/Decline Ratio in trading
The Advance/Decline Ratio (AD Ratio) is a market breadth indicator, calculated by placing the number of advancing stocks over the number of declining stocks for a day or time period in order to view the direction of the market. It is one way of viewing the daily breadth, or difference in the number of advancing issues and declining issues. 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...

What is an 'expiration date' in reference to option trading?
An ‘expiration date’ refers to the time when an option contract must either be acted upon by the owner (buying or selling the security in question) or left to expire. With derivatives such as options and futures, there will be an expiry, or expiration date in the contract, after which they expire worthlessly. Most options contracts will expire in 3, 6 or 9 months from when they are generated, and they all share the same expiration day of the month on their contracts in the United States, which is the 3rd Friday of the month at 4 PM. Continue reading...
How to use the Relative Strength Index (RSI) in trading
The Relative Strength Index (RSI) was developed by J. Welles Wilder Jr. to measure asset momentum using price changes and the speed of those changes. Like stochastics, the RSI is an oscillator that reads between 0 and 100; in this case, the RSI calculation determines the ratio of upward and downward movement using 14 periods of data, then smooths it out so only strong trends approach 0 or 100. Traders traditionally interpret RSI values of 70 or greater as an indicator of an overbought asset, while values 30 or below indicate an asset has been oversold; higher or lower values (like 80 and 20) can be used to minimize the number of bought or sold readings.
