Glossary of Technical Indicators GLOSSARY OF TECHNICAL INDICATORS This book is given for reference. So readers may or may not read it. Before reading this book you should keep in mind that the numerical values given in this book may vary as per requirement. The numerical values are basically the “parameters” of the indicators. A TO Z : GLOSSARY OF TECHNICAL ANALYSIS : A A/D Line (Breadth) : The Advance/Decline Line (Breadth) is one of the oldest and most basic key indicators, plotting the number of advancing issues divided by the total number of both advancing and declining issues. The basic premise behind volume indicators, including the Accumulation/Distribution Line, is that volume precedes price. Volume reflects the amount of shares traded in a particular stock and is a direct reflection of the money flowing into and out of a stock. Many times before a stock advances, there will be period of increased volume just prior to the move. If there are more advancing issues than declining issues, the market is said to be strong or having good breadth . New highs in the index have tended to lead peaks in the market. When the line is breaking out to the upside one can usually expect the market pick up in the next few months. A/D Line Daily : The most widely used indicator of market breadth and one of the oldest is an advance/decline line. This simple but powerful indicator is constructed by taking a cumulative total of the difference of the number of NYSE issues advancing over those declining in a day. Similar indexes may be constructed for the NASDAQ, Amex, or sub- indexes. Because the number of issues listed on any of these exchanges has expanded greatly in recent years, a simple plurality of advances over declines will give greater weight to more recent years so a better way to look the numbers is to use a ratio. The A/D line is a leading indicator and will peak before the major averages because of two reasons. First because interest rates peak before stock prices by about 9 months, then interest rate sensitive stocks tend to peak before the rest of the market and pull down the A/D line. Secondly, some industries peak before others as the economy cools off and these industries and sectors will drag down the A/D line before the rest of the economy. Absolute Breadth Index : The Absolute Breadth Index is a market momentum indicator developed by Norman G. Fosback that displays the activity, volatility, and change taking place on the New York Stock Exchange. It calculates the difference between the advancing issues and declining issues and, by dropping the sign (taking the absolute value), discards the actual direction prices are headed. By discarding market direction, the ABI functions as an "activity index." High values indicate market activity and change, while low readings indicate a lack of change. Fosback has noted historically high values typically lead to higher prices three to twelve months later. One highly reliable variation of the Absolute Breadth Index is to divide the weekly ABI by the total issues traded. If after a ten-week moving average is calculated and readings are above 40%, they are said to be very bullish. Readings below 15% are bearish. The Absolute Breadth Index is calculated by subtracting the number of declining issues from the number of advancing issues and taking the absolute value of the difference: ABI = |Advancing Issues - Declining issues| recalling that |-100| = 100 = |+100| Accumulation Swing Index : Developed by Welles Wilder, the Accumulation Swing Index is a cumulative total of the Swing Index. It compares current prices and previous prices to illustrate the 'real' price of a security. As Wilder said, "Somewhere amidst the maze of Open, High, Low and Close prices is a phantom line that is the real market." The Accumulation Swing Index is his attempt to show that line and provide a numerical value to quantify price swings. With the Accumulation Swing Index attempting to show the "real market," it closely resembles actual prices. This allows usage of classic support/resistance analysis on the Index. Typical analysis involves looking for breakouts, new highs and lows, and divergences. The summary of the calculation for the Accumulation Swing Index is: Previous Accumulation Swing Index + Swing Index Step-by-step instructions on calculating the Swing Index are provided in Wilder's book, New Concepts In Technical Trading Systems. Accumulation/Distribution Line : The Accumulation/Distribution Line was developed by Marc Chaikin to assess the cumulative flow of money into and out of a security. He decided to focus on the price action for a given period (day, week, month) and derived a formula to calculate a value based on the location of the close, relative to the range for the period. This is the "Close Location Value" or CLV. The CLV ranges from plus one to minus one with the center point at zero. The signals for the Accumulation/Distribution Line are fairly straightforward and involve divergence or confirmation. A bullish signal is given when the Accumulation/Distribution Line forms a positive divergence. Be wary of weak positive divergences that fail to make higher reaction highs. A two-week positive divergence should be suspect. However, a multi-month positive divergence deserves serious attention. The Accumulation/Distribution Line can also be used to confirm the strength or sustainability behind an advance. In a healthy advance, the Accumulation/Distribution Line should remain up or at least move in an uptrend. If the stock is moving up at a rapid pace, but the Accumulation/Distribution Line has trouble making higher highs or starts going sideways, buying pressure is relatively weak. The Accumulation/Distribution Line can at time have problems detecting subtle changes in volume flows. The rate of change in a downtrend could be slowing, but it may be impossible to detect until the Accumulation/Distribution Line turns up. This drawback has been addressed in the form of the Chaikin Oscillator or Chaikin Money Flow. Advance/Decline Line : The Advance/Decline Line (A/D Line) is one the most widely used measures of market breadth. As a cumulative total of the Advancing-Declining Issues indicator, the A/D Line has proven to be a very effective gauge of the market's strength. The A/D Line is calculated from the running total of advancing stocks minus declining stocks. Designed to measure the strength of the market, a sector or industry, it makes the basic underlying assumption that as long as there are more advancing issues than declining issues, the market remains strong. While a stock index is a composite of stock prices, the A/D Line is a composite of stock movement . This gives the daily A/D Line a downward bias relative to the weekly A/D Line and the price-based indices. This downward bias is a result of the average stock tending to have as many up days as down days, but ultimately the gains will tend to accumulate faster than the losses. The A/D Line can function as a measure of overall market strength. When more stocks are advancing than declining, the A/D Line moves up. When declining stocks outnumber advancing stocks the A/D Line will move down. Many feel that the A/D Line shows market strength better than the more commonly reported Dow Jones Industrial Average (DJIA) or the S&P 500 Index. Studying the trend of the A/D Line can illustrate if the market is in a rising or falling trend, if the trend is still intact, or how long a current trend has prevailed. The A/D Line can also be used to spotlight a divergence between itself the DJIA or a similar index. Often, an end to a bull market can be predicted when the A/D Line begins to round over even while the DJIA is trying to make new highs. Historically, when a divergence develops between the DJIA and the A/D Line, it is the DJIA that has changed direction and moved in the direction of the A/D Line. Advance/Decline Ratio : The Advance/Decline Ratio (A/D Ratio) illustrates the ratio of advancing issues to declining issues. This is used to display market breadth and while similar to the Advancing-Declining Issues, the A/D Ratio remains constant regardless of the number of issues that are traded on the New York Stock Exchange (which has steadily increased). This indicator's value is demonstrated by its ability as an overbought/oversold indicator. When the indicator moves towards its upper limits this is inidcative of a overbought situation and implies a correction may occur soon. When the indicator is towards its lower limits this is indicative of an oversold situation and suggests a technical rally is due. Day- to-day fluctuations of the Advance/Decline Ratio are often eliminated by smoothing the ratio with a moving average. Advancing-Declining Issues : Advancing-Declining Issues is a market momentum indicator used to show the difference between advancing issues and declining issues on the New York Stock Exchange. This information is used to determine the strength of the market on a daily basis. The formula for the Advancing-Declining Issues is simple: Advancing Issues - Declining Issues This calculation is is the basis of many market breadth indicators, including the Advance/Decline Line, Advance/Decline Ratio, Absolute Breadth Index, Breadth Thrust, McClellan Oscillator and Summation Index. Indicators that use advancing and declining issues in their calculations are called market breadth indicators. Plotted by itself, this indicator is helpful to determine daily market strength. Strong up days can have readings of more than +1,000.

Stock price forecasting is one of the most complicated issues in view of the high fluctuation of the stock exchange and also it is a key issue for traders and investors. Many predicting models were upgraded by academy investigators to predict stock price. Despite this, after reviewing the past research, there are several negative aspects in the previous approaches, namely: (1) stringent statistical hypotheses are essential; (2) human interventions take part in predicting process; and (3) an appropriate range is complex to be discovered. Due to the problems mentioned, we plan to provide a new integrated approach based on Artificial Bee Colony (ABC), Adaptive Neuro-Fuzzy Inference System (ANFIS), and Support Vector Machine (SVM).

  • 3 Ways to Spot Trend Reversals with the Mass Index
    3 Ways to Spot Trend Reversals with the Mass Index If you carefully observe any bar chart, you can see that even when the stock price is trending upwards or downwards, the price is actually ranging. The only difference between trending and ranging markets is the direction of the range. Once you draw an equidistant channel on any price chart, the ranging nature of price becomes more evident. Figure 1: Theory Behind the Mass Index Indicator When Donald Dorsey developed the Mass Index indicator, his rationale was that if the prevailing trend were going to change, the price range would have to widen. If you are having difficulty imagining the situation, look at figure 1, do you see what we mean? Although the Mass Index is great at signaling a potential change in the trend, it will not tell you which direction the trend is changing. After all, an uptrend can gain additional bullish momentum and that will also help make the range much wider. You have to remember that when the Mass Index technical indicator line is going up, the climbing line is only signaling that the volatility of the stock is going up. However, the Mass Index indicator line does not signify any directional bias of the stock. That’s why you need to incorporate other technical analysis tools into your mass index trading strategies in order to identify the change of direction of the prevailing trend. Consider an analogy for a moment, you are driving a car and the mass index calculator, which shows volatility of the stock, is your speedometer.

  • A Survey of Forex and Stock Price Prediction Using Deep Learning
    Review A Survey of Forex and Stock Price Prediction Using Deep Learning Zexin Hu †, Yiqi Zhao † and Matloob Khushi * School of Computer Science, The University of Sydney, Building J12/1 Cleveland St., Camperdown, NSW 2006, Australia; [email protected] (Z.H.); [email protected] (Y.Z.) * Correspondence: [email protected] † The authors contributed equally; both authors should be considered the first author. Abstract: Predictions of stock and foreign exchange (Forex) have always been a hot and profitable area of study. Deep learning applications have been proven to yield better accuracy and return in the field of financial prediction and forecasting. In this survey, we selected papers from the Digital Bibliography & Library Project (DBLP) database for comparison and analysis. We classified papers according to different deep learning methods, which included Convolutional neural network (CNN); Long Short-Term Memory (LSTM); Deep neural network (DNN); Recurrent Neural Network (RNN); Reinforcement Learning; and other deep learning methods such as Hybrid Attention Networks (HAN), self-paced learning mechanism (NLP), and Wavenet. Furthermore, this paper reviews the dataset, variable, model, and results of each article. The survey used presents the results through the most used performance metrics: Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE), Mean Absolute Error (MAE), Mean Square Error (MSE), accuracy, Sharpe ratio, and return rate. We identified that recent models combining LSTM with other methods, for example, DNN, are widely researched. Reinforcement learning and other deep learning methods yielded great returns and performances. We conclude that, in recent years, the trend of using deep-learning-based methods for financial modeling is rising exponentially.

After a decline, a stock may start to base and trade sideways for an extended period. While this base builds, well-informed traders and investors may seek to establish or increase existing long positions. In that case, the stock is said to have come under accumulation. Accumulation Distribution Line A momentum indicator that relates price changes with volume. It relates the closing price to the range of prices (H - L). The closer the close is to the high, the more volume is added to the cumulative total. Advance Decline Line One of the most widely used indicators to measure the breadth of a stock market advance or decline. The AD line tracks the net difference between advancing and declining issues. It is usually compared to a market average WWW.ISFM.CO.INwhere divergence from that average would be an early indication of a possible trend reversal. AdvanceBest Decline Stock Ratio Market School The ratio of advancing issues over declining issues. Taking the moving average of the AD ratioGurgaon will smooth it so it can be used as an overbought and oversold indicator.

DOI: 10.3934/math.2020293 Received: 09 January 2020 Accepted: 30 April 2020 http://www.aimspress.com/journal/Math Published: 22 May 2020 Research article Stock selection strategy of A-share market based on rotation effect and random forest Shuai Wang1, Zhongyan Li2;∗, Jinyun Zhu2, Zhicen Lin2 and Meiru Zhong1 1 Department of Finance, Guangdong University of Finance and Economics, Guangzhou City, Guangdong Province, China 2 Department of statistics and mathematics, Guangdong University of Finance and Economics, Guangzhou City, Guangdong Province, China * Correspondence: Email: [email protected]; Tel: +136313391161. Abstract: Due to the random nature of stock market, it is extremely difficult to capture market trends with traditional subjective analysis. Besides, the modeling and forecasting of quantitative investment strategies are not easy. Based on the research of experts and scholars at home and abroad and the rotation effect of large and small styles in China’s A-share market, a stock picking strategy combining wheeling effect and random forest is proposed. Firstly, judge the style trend of the A-share market, that is, the relatively strong style in the large and small-sized market. The strategy first judges the trend of the A-share market style, then uses a multi-factor stock selection model through random forest to select stocks among the constituent stocks of the dominant style index, and buys the selected stocks according to the optimal portfolio weights determined by the principle of minimum variance. The empirical results show that the annualized rate of return of the strategy in the eight years from January 1, 2012 to April 1, 2020 is 3.6% higher than that of the single-round strategy, far exceeding the performance of the CSI 300 Index during the same period.
