August 2005. Industrial and Manufacturing Systems Engineering An Integrated Stock Market Forecasting Model Using Neural Networks (126pp.) Director of Thesis: Gary Weckman This thesis focuses on the development of a stock market forecasting model based on an Artificial Neural Network architecture. This study constructs a hybrid model utilizing various technical indicators, Elliott’s wave theory, sensitivity analysis and fuzzy logic. Initially, a baseline network is constructed based on available literature. The baseline model is then improved by applying several useful information domains to the different models. Optimizations of the Neural Network models are performed by augmenting the network with useful information at every stage.

The following figure shows how the Bullish Engulfing Pattern looks like. The following conditions must be met for a pattern to be a bullish engulfing. 1. The stock is in a downtrend (short term or long term) 2. The first candle is a red candle (down day) and the second candle must be white (up day) 3. The body of the second candle must completely engulfs the first candle. The following conditions strengthen the buy signal 1. The trading volume is higher than usual on the engulfing day 2. The engulfing candle engulfs multiple previous down days. 3. The stock gap up or trading higher the next day after the bullish engulfing pattern is formed.

  • Trend Following Algorithms in Automated Derivatives Market Trading ⇑ Simon Fong , Yain-Whar Si, Jackie Tai
    Expert Systems with Applications 39 (2012) 11378–11390 Contents lists available at SciVerse ScienceDirect Expert Systems with Applications journal homepage: www.elsevier.com/locate/eswa Trend following algorithms in automated derivatives market trading ⇑ Simon Fong , Yain-Whar Si, Jackie Tai Department of Computer and Information Science, University of Macau, Macau article info abstract Keywords: Trend following (TF) is trading philosophy by which buying/selling decisions are made solely according to Trend following the observed market trend. For many years, many manifestations of TF such as a software program called Automated trading system Turtle Trader, for example, emerged in the industry. Surprisingly little has been studied in academic Futures contracts research about its algorithms and applications. Unlike financial forecasting, TF does not predict any mar- Mechanical trading ket movement; instead it identifies a trend at early time of the day, and trades automatically afterwards by a pre-defined strategy regardless of the moving market directions during run time. Trend following trading has been popular among speculators. However it remains as a trading method where human judgment is applied in setting the rules (aka the strategy) manually. Subsequently the TF strategy is exe- cuted in pure objective operational manner. Finding the correct strategy at the beginning is crucial in TF. This usually involves human intervention in first identifying a trend, and configuring when to place an order and close it out, when certain conditions are met. In this paper, we evaluated and compared a col- lection of TF algorithms that can be programmed in a computer system for automated trading. In partic- ular, a new version of TF called trend recalling model is presented.

  • New Elliott Wave Principle
    History The Elliott Wave Theory is named after Ralph Nelson Elliott. In the 1930s, Ralph Nelson Elliott found that the markets exhibited certain repeated patterns. His primary research was with stock market data for the Dow Jones Industrial Average. This research identified patterns or waves that recur in the markets. Very simply, in the direction of the trend, expect five waves. Any corrections against the trend are in three waves. Three wave corrections are lettered as "a, b, c." These patterns can be seen in long-term as well as in short-term charts. In Elliott's model, market prices alternate between an impulsive, or motive phase, and a corrective phase on all time scales of trend, as the illustration shows. Impulses are always subdivided into a set of 5 lower-degree waves, alternating again between motive and corrective character, so that waves 1, 3, and 5 are impulses, and waves 2 and 4 are smaller retraces of waves 1 and 3. Corrective waves subdivide into 3 smaller-degree waves. In a bear market the dominant trend is downward, so the pattern is reversed—five waves down and three up. Motive waves always move with the trend, while corrective waves move against it and hence called corrective waves. Ideally, smaller patterns can be identified within bigger patterns. In this sense, Elliott Waves are like a piece of broccoli, where the smaller piece, if broken off from the bigger piece, does, in fact, look like the big piece. This information (about smaller patterns fitting into bigger patterns), coupled with the Fibonacci relationships between the waves, offers the trader a level of anticipation and/or prediction when searching for and identifying trading opportunities with solid reward/risk ratios.

  • 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.

Lane and are used to help predict the future direction of an exchange rate. The Oscillator scale ranges from 0 to 100. When calculating the strength of a trend, the Stochastic Oscillator defines and uptrend as the period of time w hen rates remain equal to or higher than the previous close, w hile a downtrend is the period of time w hen rates remain equal to or low er than the previous close. The Full Stochastic consists of tw o stochastic lines - %K and %D w here: %K tracks the current rate for the currency pair %D is a moving average based on the %K line - the fact that it is an average of %K means that it w ill produce a "smoothed out" version of %K The %K line is commonly referred to as the Fast Stochastic as it moves w ith changes in the spot rate w hile the %D line - w hich is a moving average of the %K line - reacts more slow ly to rate changes. For this reason, it is often referred to as the Slow Stochastic. Crossovers occur w hen the %K line intersects the %D line.

  • Stochastic Pop & Drop Strategies
    Stochastic Pop & Drop Strategies Establish a Trading Bias •Establish a short-term trading bias with a long-term indicator. •Traders look for bullish setups when the bias is bullish and bearish setups when the bias is bearish. •Trading in the direction of this bias is like riding a bike with the wind at your back. The chances of success are higher when the bigger trend is in your favor. •Use the weekly Stochastic Oscillator to define the trading bias. •In particular, the trading bias is deemed bullish when the weekly 14-period Stochastic Oscillator is above 50 and rising, and vice versa for bearish bias •Use a 70-period daily Stochastic Oscillator so all indicators can be displayed on the chart **This timeframe is simply five times the 14-day timeframe. Stochastic Pop Stochastic Pop Buy Signal •70-day Stochastic Oscillator is above 50 •14-day Stochastic Oscillator surges above 80 •Stock rises on high volume and/or breaks consolidation resistance. •Candle pattern confirmation Stochastic Pop •Once the bullish prerequisites are in place, a buy signal triggers when the 14-day Stochastic Oscillator surges above 80 and the stock breaks out on above average volume. •Consolidation breakouts are preferred when using this strategy (ie Box range) •Do not ignore high volume signals that do not produce breakouts •Sometimes the initial high-volume surge is a precursor to a breakout Box Range / Consolidation Trending Market Trending Market Trending Market Trending Market / Box Range Stochastics Stochastic Drop Stochastic Drop Sell Signal •70-day Stochastic Oscillator is below 50 •14-day Stochastic Oscillator plunges below 20 •Stock declines on high volume and/or breaks consolidation support.

  • Trading Strategies Using Stochastic
    ANALYSIS TOOLS By Ng Ee Hwa, ChartNexus Market Strategist TRADING STRATEGIES USING STOCHASTIC In the aftermath of the global market correction following the big drop in the Chinese stock market indices in Feb 2007, investors have returned to the markets with a vengeance pushing the indices to scale new heights almost daily. However with recent moves by the Chinese authorities to cool the bullishness through measures such as the increase in stamp duties, the Chinese stock markets have again dropped significantly in the first few days of June 2007. This example of wild swings in the market sentiment can cause serious damage to the retail investor’s pocket, especially those uneducated in the forces at play in the stock market. Consequently it is vital that investors and traders are well-equipped in technical analysis tools to time the market effectively. This article will look at one of the tools in Technical Analysis indicators called Stochastic, a momentum indicator that shows clear bullish and bearish signals. Stochastic is a momentum oscillator oscillators that oscillate in a fixed range, an developed by George C.Lane in the late 1950s. overbought and oversold condition can be Lane noticed that in an up trending stock, prices specified. Based on his trading experience, Lane will usually make higher highs and the daily closing defined the overbought and oversold region for price will tend to accumulate near the extreme the Stochastic value to be above 80 and below highs of the “look back” periods. Similarly, a down 20 respectively. He deemed that a Stochastic value trending stock demonstrated the same behavior above 80 or below 20 may signal that a price trend of which the daily closing price tends to reversal may be imminent.
