Overview

In this project you will design a learning trading agent. You must draw on the learners you have created so far in the course. Your choices are:

• Create a regression or classification-based strategy using your Random Forest learner.
• Create a Q-learning-based strategy using your Q-Learner.
• Create a scan-based strategy using an optimizer.

Your learner should work in the following way:

• In the training phase (e.g., addEvidence()) your learner will be provided with a stock symbol and a time period. It should use this data to learn its strategy. For instance, for a regression-based learner it will use this data to make predictions about future price changes.
• In the testing phase (e.g., testPolicy()) your learner will be provided a symbol and a date range. All learning should be turned OFF during this phase.

If the date range is the same as used for the training, it is an in-sample test. Otherwise it is an out-of-sample test. Your learner should return a set of dated trades similar to those input to your market simulator.

Here are some important requirements: Your testPolicy() method should be much faster than your addEvidence() method. The timeout requirements (see rubric) will be set accordingly. Multiple calls to your testPolicy() method should return exactly the same result.

Overall, your tasks for this project include:

• Devise numerical/technical indicators to evaluate the state of a stock on each day.
• Build a strategy learner based on one of the learners described above that uses the indicators.
• Test/debug the strategy learner on specific symbol/time period problems.
• Write a report describing your learning strategy.

Scoring for the project will be based on trading strategy test cases.

Template and Data

• Update your local mc3_p4 directory using github.
• Place your existing Q-Learner or RTLearner or OptimizationLearner into mc3_p4/.
• Implement the StrategyLearner class in mc3_p4/StrategyLearner.py
• ALL of your code should be contained in the two files listed above.
• To test your strategy learner, run python teststrategylearner.py from the mc3_p4/ directory.

Use the following parameters for trading and evaluation:

• Use only the data provided for this course. You are not allowed to import external data.
• Allowable positions are: 200 shares long, 200 shares short, 0 shares.
• Benchmark:
  • The performance of a portfolio starting with $100,000 cash, then investing in 200 shares of the relevant symbol and holding that position
• There is no limit on leverage.

Implement Strategy Learner

For this part of the project you should develop a learner that can learn a trading policy using your learner. You should be able to use your Q-Learner or RTLearner from the earlier project directly, with no changes. If you want to use the optimization approach, you will need to create new code or that. You will need to write code in StrategyLearner.py to "wrap" your learner appropriately to frame the trading problem for it. Utilize the template provided in StrategyLearner.py.

Your StrategyLearner should implement the following API:

import StrategyLearner as sl
learner = sl.StrategyLearner(verbose = False) # constructor
learner.addEvidence(symbol = "AAPL", sd=dt.datetime(2008,1,1), ed=dt.datetime(2009,12,31), sv = 100000) # training phase
df_trades = learner.testPolicy(symbol = "AAPL", sd=dt.datetime(2010,1,1), ed=dt.datetime(2011,12,31), sv = 100000) # testing phase

The input parameters are:

• verbose: if False do not generate any output
• symbol: the stock symbol to train 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 data frame whose values represent trades for each day. Legal values are +200.0 indicating a BUY of 200 shares, -200.0 indicating a SELL of 200 shares, and 0.0 indicating NOTHING. Values of +400 and -400 for trades are also legal so long as net holdings are constrained to -200, 0, and 200.

What to turn in

Turn your project in via t-square. Your submission should include exactly 3 files. All of your code must be contained within two files: your learner and StrategyLearner.py.

• Your learner.
• Your StrategyLearner as StrategyLearner.py
• Your report as report.pdf
• Do not submit any other files.

Rubric

Code: 60 points

We will test StrategyLearner in the following situations:

• Training / in sample: January 1, 2008 to December 31 2009.
• Testing / out of sample: January 1, 2010 to December 31 2011.
• Symbols: ML4T-220, AAPL, UNH, SINE_FAST_NOISE
• Starting value: $100,000
• Benchmark: Buy 200 shares on the first trading day, Sell 200 shares on the last day.

We expect the following outcomes in evaluating your system:

• For ML4T-220
  • addEvidence() completes without crashing within 25 seconds: 1 points
  • testPolicy() completes in-sample within 5 seconds: 2 points
  • testPolicy() returns same result when called in-sample twice: 2 points
  • testPolicy() returns an in-sample result with cumulative return greater than 100%: 5 points
  • testPolicy() returns an out-of-sample result with cumulative return greater than 100%: 5 points
• For AAPL
  • addEvidence() completes without crashing within 25 seconds: 1 points
  • testPolicy() completes in-sample within 5 seconds: 2 points
  • testPolicy() returns same result when called in-sample twice: 2 points
  • testPolicy() returns an in-sample result with cumulative return greater than benchmark: 5 points
  • testPolicy() returns an out-of-sample result within 5 seconds: 5 points
• For SINE_FAST_NOISE
  • addEvidence() completes without crashing within 25 seconds: 1 points
  • testPolicy() completes in-sample within 5 seconds: 2 points
  • testPolicy() returns same result when called in-sample twice: 2 points
  • testPolicy() returns an in-sample result with cumulative return greater than 200%: 5 points
  • testPolicy() returns an out-of-sample result within 5 seconds: 5 points
• For UNH
  • addEvidence() completes without crashing within 25 seconds: 1 points
  • testPolicy() completes in-sample within 5 seconds: 2 points
  • testPolicy() returns same result when called in-sample twice: 2 points
  • testPolicy() returns an in-sample result with cumulative return greater than benchmark: 5 points
  • testPolicy() returns an out-of-sample result within 5 seconds: 5 points

We reserve the right to use different time periods if necessary to reduce auto grading time.

Rubric TBD

Required, Allowed & Prohibited

Required:

• Your project must be coded in Python 2.7.x.
• Your code must run on one of the university-provided computers (e.g. buffet02.cc.gatech.edu).
• All code must be your own.
• No external learning libraries allowed.

Allowed:

• You can develop your code on your personal machine, but it must also run successfully on one of the university provided machines or virtual images.
• Your code may use standard Python libraries.
• You may use the NumPy, SciPy, matplotlib and Pandas libraries. Be sure you are using the correct versions.
• You may reuse sections of code (up to 5 lines) that you collected from other students or the internet.
• Code provided by the instructor, or allowed by the instructor to be shared.
• Use util.py (only) for reading data.

Prohibited:

• Any libraries not listed in the "allowed" section above.
• Any code you did not write yourself (except for the 5 line rule in the "allowed" section).
• Any Classes (other than Random) that create their own instance variables for later use (e.g., learners like kdtree).
