Welcome to the world of machine learning and stock market predictions! In this article, we will explore how to use a beginner-friendly project called MachineLearningStocks to predict stock movements. This guide will help you understand the workflow of applying machine learning to financial data and inspire you to make your own improvements. Ready to dive in? Let’s get started!

Overview

The process of using machine learning for stock prediction generally breaks down into several steps:

1. Acquire historical **fundamental data**—these are the features or predictors.
2. Acquire historical **stock price data**—this will form our dependent variable, what we want to predict.
3. Preprocess the data.
4. Use a machine learning model to learn from the data.
5. Backtest the performance of the machine learning model.
6. Gather current fundamental data.
7. Generate predictions from the current data.

Getting Started: Quickstart Guide

If you’re eager to get straight into the action, here’s how to do it:

• Clone the MachineLearningStocks project.
• Download and unzip the data file into the same directory.
• Open a terminal and navigate to the project directory.
• Install the required libraries using:

pip install -r requirements.txt

• Run the scripts in the following order:

python download_historical_prices.py
python parsing_keystats.py
python backtesting.py
python current_data.py
pytest -v
python stock_prediction.py

Understanding the Data Preparation Process Through Analogy

Think of preparing your data like getting ready for a big cooking competition. You can’t just throw all the ingredients (data) together without some preparation. Here’s how the process works:

• Gathering Ingredients: You start by acquiring historical stock price and fundamental data, just like gathering ingredients for a recipe.
• Cleaning the Ingredients: Just as you would wash vegetables and trim off bad parts, you’ll clean your data to ensure it’s usable.
• Chopping and Measuring: In cooking, you chop and measure your ingredients. Here, you’ll preprocess data, applying transformations and encoding.
• Cooking: Finally, you mix all the ingredients according to the recipe—your machine learning model learns from the data!
• Tasting: You taste the dish to ensure it’s good. This is similar to backtesting the model to evaluate its performance.

Backtesting: Testing Your Predictions

Backtesting is crucial for validating your predictions. By simulating trades, you can evaluate how well your model performs without risking real money. Run the backtesting script with:

python backtesting.py

You should see results showing your model’s accuracy and performance against the market benchmark.

Troubleshooting: What to Do When Things Don’t Work

If you encounter issues, here are some troubleshooting tips:

• Ensure you are using Python 3.6 or higher to avoid syntax errors with f-strings.
• If data downloads are failing, check the current state of Yahoo Finance for any changes that need adjustments in the code.
• Experiment with different classifiers or tweak hyperparameters to improve prediction results.
• Review the code in parsing_keystats.py if data parsing is unsuccessful.
