Project 6: Indicator Evaluation

Revisions

This assignment is subject to change up until 3 weeks prior to the due date. We do not anticipate changes; any changes will be logged in this section.

1 Overview

In this project, you will develop technical indicators and a Theoretically Optimal Strategy that will be the ground layer of a later project (i.e., project 8). The technical indicators you develop here will be utilized in your later project to devise an intuition-based trading strategy and a Machine Learning based trading strategy. The Theoretically Optimal Strategy will give a baseline to gauge your later project’s performance. We hope Machine Learning will do better than your intuition, but who knows? You will submit the code for the project to Gradescope SUBMISSION. The report will be submitted to Canvas. 

1.1 Learning Objectives

The specific learning objectives for this assignment are focused on the following areas: 

  • Indicators: You will develop an understanding of various trading indicators and how they might be used to generate trading signals.  
  • Optimal Strategy: You will also develop an understanding of the upper bounds (or maximum) amount that can be earned through trading given a specific instrument and timeframe. 

2 About the Project

Please keep in mind that the completion of this project is pivotal to Project 8 completion. The indicators that are selected here cannot be replaced in Project 8. We encourage spending time finding and researching indicators, including examining how they might later be combined to form trading strategies. Considering how multiple indicators might work together during Project 6 will help you complete the later project. 

3 Your Implementation

This project has two main components: First, you will research and identify five market indicators. For each indicator, you will write code that implements each indicator. Second, you will develop a theoretically optimal strategy (TOS), which represents the maximum amount your portfolio can theoretically return.  

Before the deadline, make sure to pre-validate your submission using Gradescope TESTING. Once you are satisfied with the results in testing, submit the code to Gradescope SUBMISSION. Only code submitted to Gradescope SUBMISSION will be graded. If you submit your code to Gradescope TESTING and have not also submitted your code to Gradescope SUBMISSION, you will receive a zero (0). 

3.1 Getting Started

This framework assumes you have already set up the local environment and ML4T Software. There is no distributed template for this project. 

You will have access to the ML4T/Data directory data, but you should use ONLY the API functions in util.py to read it. You may create a new folder called indicator_evaluation to contain your code for this project. 

You should create the following code files for submission. They should contain ALL code from you that is necessary to run your evaluations.  

  • indicators.py 
    Code implementing your indicators as functions that operate on DataFrames. The “main” method in indicators.py should generate the charts that illustrate your indicators in the report.  
  • marketsimcode.py 
    An improved version of your marketsim code accepts a “trades” DataFrame (instead of a file). More info on the trades data frame is below. It is OK not to submit this file if you have subsumed its functionality into one of your other required code files. This file has a different name and a slightly different setup than your previous project. However, that solution can be used with several edits for the new requirements. 
  • TheoreticallyOptimalStrategy.py 
    Code implementing a TheoreticallyOptimalStrategy (details below). It should implement testPolicy(), which returns a trades data frame (see below).   
  • testproject.py 
    This file should be considered the entry point to the project. The if “__name__” == “__main__”: section of the code will call the testPolicy function in TheoreticallyOptimalStrategy, as well as your indicators and marketsimcode as needed, to generate the plots and statistics for your report (more details below).  
  • README.txt  
    This is a text file that describes each .py file and provides instructions describing how to run your code. 

    3.2 Data, Details, Dates & Rules

    • Use only the data provided for this course. You are not allowed to import external data.  
    • Add an author() function to each file.  
    • For your report, use only the symbol JPM.  
    • Use the time period January 1, 2008, to December 31, 2009.  
    • Starting cash is $100,000.  
    • Allowable positions are 1000 shares long, 1000 shares short, 0 shares. (You may trade up to 2000 shares at a time as long as you maintain these holding requirements.)  
    • Benchmark: The performance of a portfolio starting with $100,000 cash, investing in 1000 shares of JPM, and holding that position.  
    • Transaction costs for TheoreticallyOptimalStrategy:  
    • Commission: $0.00
    • Impact: 0.00. 

          3.3 Implement Part 1: Theoretically Optimal Strategy

          In the Theoretically Optimal Strategy, assume that you can see the future. You are constrained by the portfolio size and order limits as specified above. Create a set of trades representing the best a strategy could possibly do during the in-sample period using JPM. We have you do this to have an idea of an upper bound on performance, which can be referenced in Project 8.    

          Note: The Theoretically Optimal Strategy does not use the indicators developed in the previous section.  

          Use the revised market simulator based on the one you wrote earlier in the course to determine the portfolio valuation.  For this activity, use $0.00 and 0.0 for commissions and impact, respectively.  

          Provide a chart that reports:  

          • Benchmark (see definition above) normalized to 1.0 at the start: Plot as a green line 
          • Value of the theoretically optimal portfolio (normalized to 1.0 at the start): Plot as a red line 

          You should also report, as a table, in your report:  

          • Cumulative return of the benchmark and portfolio  
          • Stdev of daily returns of benchmark and portfolio  
          • Mean of daily returns of benchmark and portfolio  

          Your TOS should implement a function called ‘testPolicy()’ as follows:  

          The input parameters are:  

          • symbol: the stock symbol to act on  
          • sd: A DateTime object that represents the start date  
          • ed: A DateTime object that represents the end date  
          • sv: Start value of the portfolio  

            The output result is:  

            • df_trades: A single column data frame, indexed by date, whose values represent trades for each trading day (from the start date to the end date of a given period). Legal values are +1000.0 indicating a BUY of 1000 shares, -1000.0 indicating a SELL of 1000 shares, and 0.0 indicating NOTHING. Values of +2000 and -2000 for trades are also legal so long as net holdings are constrained to -1000, 0, and 1000. Note: The format of this data frame differs from the one developed in a prior project.   

            Your testproject.py code should call testPolicy() as a function within TheoreticallyOptimalStrategy as follows:  

            The df_trades result can be used with your market simulation code to generate the necessary statistics. 

            3.4 Implement Part 2: Technical Indicators 

            Develop and describe 5 technical indicators. You may find our lecture on time series processing, the Technical Analysis video, and the vectorize_me PowerPoint to be helpful. For each indicator, you should create a single, compelling chart (with proper title, legend, and axis labels) that illustrates the indicator (you can use sub-plots to showcase different aspects of the indicator).  

            For example, you might create a chart showing the stock’s price history, along with “helper data” (such as upper and lower Bollinger Bands) and the value of the indicator itself. Another example: If you were using price/SMA as an indicator, you would want to create a chart with 3 lines: Price, SMA, Price/SMA. To facilitate visualization of the indicator, you might normalize the data to 1.0 at the start of the date range (i.e., divide price[t] by price[0]).  

            In your report (described below), a description of each indicator should enable someone to reproduce it just by reading the description. We want a written detailed description here, not code. However, it is OK to augment your written description with a pseudocode figure. Do NOT copy/paste code parts here as a description 

            You should have already successfully coded the Bollinger Band feature:  

            Another good indicator worth considering is momentum.  

            You can use util.py to read any of the columns in the stock symbol files.  

            It is usually worthwhile to standardize the resulting values (see Standard Score).  

            You are allowed to use up to two indicators presented and coded in the lectures (SMA, Bollinger Bands, RSI), but the other three will need to come from outside the class material (momentum is allowed to be used).  

            The indicators should return results that can be interpreted as actionable buy/sell signals. For example, Bollinger Bands alone does not give an actionable signal to buy/sell easily framed for a learner, but BBP (or %B) does.  

            3.4.1 Planning Ahead

            In Project-8, you will need to use the same indicators you will choose in this project. You will not be able to switch indicators in Project 8. Some indicators are built using other indicators and/or return multiple results vectors (e.g., MACD uses EMA and returns MACD and Signal vectors). While such indicators are okay to use in Project 6, please keep in mind that Project 8 will require that each indicator return one results vector. In this case, MACD would need to be modified for Project 8 to return your own custom results vector that somehow combines the MACD and Signal vectors, or it would need to be modified to return only one of those vectors. If you use an indicator in Project 6 that returns multiple results vectors, we recommend taking an additional step of determining how you might modify the indicator to return one results vector for use in Project 8. While Project 6 doesn’t need to code the indicators this way, it is required for Project 8.   

            You may not use stand-alone indicators with different parameters in Project 8 (e.g., SMA(5) and SMA(30)). This means someone who wants to implement a strategy that uses different values for an indicator (e.g., a Golden Cross that uses two SMA calls with different parameters) will need to create a Golden_Cross indicator that returns a single results vector, but internally the indicator can use two SMA calls with different parameters). This Golden_Cross indicator would need to be defined in Project 6 to be used in Project 8. 

            You may not use an indicator in Project 8 unless it is explicitly identified in Project 6. Note that an indicator like MACD uses EMA as part of its computation. If you want to use EMA in addition to using MACD, then EMA would need to be explicitly identified as one of the five indicators.   

            3.5 Part 3: Implement author() function (deduction if not implemented) 

            You should implement a function called author() that returns your Georgia Tech user ID as a string in each .py file. This is the ID you use to log into Canvas. It is not your 9 digit student number. Here is an example of how you might implement author():  

            Implementing this method correctly does not provide any points, but there will be a penalty for not implementing it.  

            3.6 Part 4: Implement Test Project

            Create testproject.py and implement the necessary calls (following each respective API) to indicators.py and TheoreticallyOptimalStrategy.py, with the appropriate parameters to run everything needed for the report in a single Python call. You may also want to call your market simulation code to compute statistics. The file will be invoked using the command 

            This is to have a single–entry point to test your code against the report. Calling testproject.py should run all assigned tasks and output all necessary charts and statistics for your report.  

            3.7 Part 5: Implement README.txt

            You must also create a README.txt file that has:  

            • Description of what each python file is for/does.  
            • Explicit instructions on how to properly run your code. 

              3.8 Technical Requirements

              The following technical requirements apply to this assignment 

              1. Use only the functions in util.py to read in stock data. Only use the API methods provided in that file. Please note that util.py is considered part of the environment and should not be moved, modified, or copied. For grading, we will use our own unmodified version.  
              2. An indicator can only be used once with a specific value (e.g., SMA(12)). If you need to use multiple values, consider creating a custom indicator (e.g., my_SMA(12,50), which internally uses SMA(12) and SMA(50) before returning a single results vector).  
              3. The implementation may optionally write text, statistics, and/or tables to a single file named p6_results.txt or p6_results.html. 
              4. The Sharpe ratio uses the sample standard deviation 

                      3.9 Hints & Recommendations

                      • The “secret” regarding leverage and a “secret date” discussed in the YouTube lecture do not apply and should be ignored.

                      4 Contents of Report

                      In addition to submitting your code to Gradescope, you will also produce a report. Your report should useJDF format and has a maximum of 10 pages.  Any content beyond 10 pages will not be considered for a grade. Ten pages is a maximum, not a target; our recommended per-section lengths intentionally add to less than 10 pages to leave you room to decide where to delve into more detail. This length is intentionally set, expecting that your submission will include diagrams, drawings, pictures, etc. These should be incorporated into the body of the paper unless specifically required to be included in an appendix.  

                      The JDF format specifies font sizes and margins, which should not be altered. Include charts to support each of your answers. Charts should also be generated by the code and saved to files. Charts should be properly annotated with legible and appropriately named labels, titles, and legends.  

                      Please address each of these points/questions in your report. The report is to be submitted as p6_indicatorsTOS_report.pdf 

                      4.1 Indicators: ~ 5 pages (estimated) 

                      At a minimum, address each of the following for each indicator:  

                      • Introduce and describe each indicator you use in sufficient detail that someone else could reproduce it. (The indicator can be described as a mathematical equation or as pseudo-code).  
                      • Provide a compelling description regarding why that indicator might work and how it could be used. Be sure to describe how they create buy and sell signals (i.e., explain how the indicator could be used alone and/or in conjunction with other indicators to generate buy/sell signals).  
                      • Provide one or more charts that convey how each indicator works compellingly. (up to 3 charts per indicator).  

                      The total number of charts for Part 1 must not exceed 10 charts.  

                      4.2 Theoretically Optimal Strategy (TOS) ~ 1.5 pages (estimated)

                      For the Theoretically Optimal Strategy, at a minimum, address each of the following:  

                      • Describe how you created the strategy and any assumptions you had to make to make it work.  
                      • Describe the strategy in a way that someone else could evaluate and/or implement it.  
                      • Provide a chart that illustrates the TOS performance versus the benchmark.  
                      • Provide a table that documents the benchmark and TOS performance metrics. These metrics should include cumulative returns, the standard deviation of daily returns, and the mean of daily returns for both the benchmark and portfolio. Performance metrics must include 4 digits to the right of the decimal point (e.g., 98.1234)   

                        5 Testing Recommendations

                        There is no locally provided grading / pre-validation script for this assignment. You are encouraged to perform any tests necessary to instill confidence in your implementation, ensure that the code will run properly when submitted for grading and that it will produce the required results.  

                        In addition to testing on your local machine, you are encouraged to submit your files to Gradescope TESTING, where some basic pre-validation tests will be performed against the code. No credit will be given for coding assignments that do not pass this pre-validation. Gradescope TESTING does not grade your assignment. The Gradescope TESTING script is not a complete test suite and does not match the more stringent private grader that is used in Gradescope SUBMISSION. Thus, the maximum Gradescope TESTING score, while instructional, does not represent the minimum score one can expect when the assignment is graded using the private grading script. You are encouraged to develop additional tests to ensure that all project requirements are met. 

                        You are allowed unlimited resubmissions to Gradescope TESTING. Please refer to the Gradescope Instructions for more information. 

                        6 Submission Requirements

                        This is an individual assignment. All work you submit should be your own. Make sure to cite any sources you reference and use quotes and in-line citations to mark any direct quotes. 

                        Assignments received after Sunday at 11:59 PM AOE (even if only by a few seconds) are not accepted without advanced agreement except in cases of medical or family emergencies. In the case of such an emergency, please contact the Dean of Students. 

                        6.1 Report Submission

                        Complete your assignment using the JDF format, then save your submission as a PDF. The report is to be submitted as p6_indicatorsTOS_report.pdf. Assignments should be submitted to the corresponding assignment submission page in Canvas. You should submit a single PDF for this assignment. Please submit the following file(s) to Canvas in PDF format only: 

                        p6_indicatorsTOS_report.pdf 

                        Do not submit any other files. All charts and tables must be included in the report, not submitted as separate files. Also note that when we run your submitted code, it should generate the charts and table. Not submitting a report will result in a penalty. 

                        You are allowed unlimited submissions of the p6_indicatorsTOS_report.pdf. 

                        6.2 Code Submission

                        This class uses Gradescope, a server-side auto-grader, to evaluate your code submission. No credit will be given for code that does not run in this environment and students are encouraged to leverage Gradescope TESTING prior to submitting an assignment for grading. Only code submitted to Gradescope SUBMISSION will be graded. If you submit your code to Gradescope TESTING and have not also submitted your code to Gradescope SUBMISSION, you will receive a zero (0). 

                        Please submit the following files to Gradescope SUBMISSION: 

                          • testproject.py  
                          • indicators.py  
                          • TheoreticallyOptimalStrategy.py  
                          • README.txt  
                          • marketsimcode.py (optional file)  

                          Do not submit any other files. 

                          Important: You are allowed a MAXIMUM of three (3) code submissions to Gradescope SUBMISSION. 

                          7 Grading Information

                          Your report and code will be graded using a rubric design to mirror the questions above. Make sure to answer those questions in the report and ensure the code meets the project requirements. Deductions will be applied for unmet implementation requirements or code that fails to run. 

                          We do not provide an explicit set timeline for returning grades, except that all assignments and exams will be graded before the institute deadline (end of the term). As will be the case throughout the term, the grading team will work as quickly as possible to provide project feedback and grades.  

                          Once grades are released, any grade-related matters must follow the Assignment Follow-Up guidelines and process alone. Regrading will only be undertaken in cases where there has been a genuine error or misunderstanding. Please note that requests will be denied if they are not submitted using the Fall 2021 form or do not fall within the timeframes specified on the Assignment Follow-Up page.

                                8 DEVELOPMENT GUIDELINES (ALLOWED & PROHIBITED) 

                                See the Course Development Recommendations, Guidelines, and Rules for the complete list of requirements applicable to all course assignments. The Project Technical Requirements are grouped into three sections: Always Allowed, Prohibited with Some Exceptions, and Always Prohibited. 

                                The following exemptions to the Course Development Recommendations, Guidelines, and Rules apply to this project: 

                                • Watermarked charts may be shared in the dedicated discussion forum mega-thread alone. 
                                • You may set a specific random seed for this assignment. If a specific random seed is used, it must only be called once within a test_code() function in the testproject.py file and it must use your GT ID as the numeric value. 

                                9 Optional Resources

                                Although the use of these or other resources is not required; some may find them useful in completing the project or in providing an in-depth discussion of the material.
