This course will explore algorithmic trading with machine learning and deep learning in depth and explain how momentum and psychological factors work together. Consequently, “the trend is your friend” can act as a core investment strategy.

1. Overview of Machine Learning and Deep Learning

Machine learning is an algorithm that learns patterns from data and makes predictions or decisions based on those patterns. In contrast, deep learning is a subset of machine learning based on artificial neural networks, which performs especially well in solving complex problems. Deep learning is suitable for processing large amounts of unstructured data and is widely used in areas such as speech recognition, image processing, and natural language processing. These technologies can also be applied in the financial market for trend prediction, price forecasting, and portfolio optimization.

2. Basics of Algorithmic Trading

Algorithmic trading is a trading method based on predefined rules and strategies. The primary goal is to execute trades quickly and consistently without emotional interference. Algorithmic trading helps make better trading decisions by combining traditional technical analysis, fundamental analysis, and new data sources. Machine learning and deep learning can be used as techniques to significantly enhance the performance of algorithmic trading.

3. Momentum Strategy: Riding the Market Flow

The momentum strategy is a trading strategy that analyzes past price trends to predict future price movements. In other words, it is based on the principle that “rising stocks tend to rise further, and falling stocks tend to fall further.” This strategy focuses on capturing significant trends in the market and trusting the persistence of those trends. Momentum factors can be analyzed and predicted based on historical data through machine learning models.

3.1 Mechanism of Momentum

Momentum is based on the fact that stocks or assets tend to show stronger and more sustained movements when trading volume is high. When a stock is rising, investors develop a positive sentiment towards that stock, which leads to additional buying pressure, thereby allowing the price to continue rising. This shows that psychological factors also play an important role.

4. Psychological Factors and Trading

Investors often make irrational decisions. These decisions stem from the investor’s psychology, including emotions and sentiments about the market. Examples include Fear of Missing Out (FOMO), Loss Aversion, and Herd Behavior. By understanding these psychological factors and incorporating them into machine learning algorithms, more effective trading strategies can be developed.

5. Algorithmic Trading Using Deep Learning

Deep learning has become a powerful predictive tool, especially in the financial environment where unstructured data is abundant. By analyzing time-series data, potential patterns can be identified, and future prices can be predicted based on those patterns. Various deep learning models, such as LSTM (Long Short Term Memory) networks and CNN (Convolutional Neural Network), can be utilized.

5.1 Trading Using LSTM

LSTM provides powerful performance in learning patterns from time-series data. This network has a unique ability to remember previous data states and generate subsequent predictions. For example, stock price data can be analyzed using LSTM to detect signals for price increase or decrease in the future.

5.2 Trading Using CNN

CNN is known for its strong performance in processing image data. By converting stock chart patterns into images and applying CNN, the shapes of past charts can be useful for predicting future price movements.

6. Monte Carlo Simulation and Risk Management
