The world of stock trading is intricate, relying on analysts to read and interpret price movements effectively. But what if machines could replicate this analytical ability? Yes, you heard it right! In this blog, we will explore how to use Convolutional Neural Networks (CNNs) to predict future trends in the stock market by reading candlestick graphs. Let’s dive into the fascinating techniques and approaches you can adopt to make this happen!
Getting Started with the Dataset
Our journey starts with acquiring a robust dataset to fuel our model training. You can obtain a comprehensive data set from Huge Stock Market Dataset: Full Historical Daily Price + Volume Data For All U.S. Stocks & ETFs. This dataset contains historical prices and volumes, forming the backbone of our predictive analytics.
Understanding the Two Approaches
There are two main approaches to train our CNN for this problem.
Approach 1: Direct Application on Data Matrices
In this approach, you’ll apply convolution directly to data matrices. The input consists of formatted matrices derived from stock metrics such as Open, High, Low, Close, and Volume. Our CNN will learn to classify trends based on these matrices.
- Input: (5*n) matrices – (Open, High, Low, Close, Volume)*(d1, d2,…, dn)
- Output: Classification results
Approach 2: Generating Candlestick Graphs
Alternatively, we can first generate candlestick graphs from the same data and let our CNN analyze those visuals. This approach not only focuses on raw numbers but also captures the aesthetic beauty of stock movements.
- Input: Candlestick graphs
- Output: Classification results
Here is a sample of a candlestick graph:
Current Results
After implementing both approaches, intriguing results began to surface. Utilizing an architecture with 11 layers and residual blocks has proven to yield impressive accuracy. Take a look at the current performance results:
Troubleshooting Tips
While embarking on this journey, you might encounter some hiccups. Here are some troubleshooting ideas:
- Ensure your dataset is clean and well-structured. Any inconsistencies could lead to poor model performance.
- If you’re facing overfitting, consider simplifying your model structure or applying techniques like dropout or data augmentation.
- Monitor your learning rates; sometimes fine-tuning them can lead to significant improvements in model performance.
- If the candlestick visualizations aren’t yielding expected results, revisit the graph generation parameters and ensure they correctly represent the data.
