In recent years, advancements in machine learning (ML) and deep learning (DL) technologies in the financial markets have significantly impacted the efficiency and performance of algorithmic trading. In particular, ML-based trading strategies enable better investment decisions through the automation of data analysis. This article will Explore & Explain the HRP (Hierarchical Risk Parity) backtesting method based on ML trading strategies.<\/p>\n
Machine learning is a field of artificial intelligence (AI) that empowers computers to learn from data and make predictions. ML algorithms are primarily used for pattern recognition and predictive modeling, allowing them to estimate future outcomes based on past data.<\/p>\n
Deep learning is a subset of machine learning that utilizes artificial neural networks to analyze data. It demonstrates exceptional performance in analyzing unstructured data (e.g., images, text) and is being utilized in various ways in the financial markets recently.<\/p>\n
The HRP (Hierarchical Risk Parity) strategy is a method that considers the correlations between asset classes to diversify risk. This approach is known for minimizing portfolio risk while maximizing returns. HRP generates a hierarchy based on the similarities between assets and optimizes the asset proportions in each layer to manage risk.<\/p>\n
HRP operates in the following steps:<\/p>\n
The main advantages of HRP are as follows:<\/p>\n
Establishing an ML trading strategy involves data collection, model selection, and backtesting phases. The following steps can be followed to develop an ML trading strategy:<\/p>\n
Diverse types of data are required to build an efficient ML model. Stock prices, trading volumes, technical indicators, and economic indicators need to be collected. Data collection can primarily be performed through APIs or crawling techniques.<\/p>\n
The collected data is preprocessed to convert it into a suitable format for the model. Major preprocessing steps include quality checks, handling missing values, and scaling.<\/p>\n
The most suitable model must be selected from several machine learning models. Commonly used models include regression, decision trees, random forests, and neural networks. Optimal performance can be achieved through hyperparameter tuning for each model.<\/p>\n
HRP backtesting evaluates the model’s performance based on historical data. This consists of the following steps:<\/p>\n
Set up the necessary libraries and tools for backtesting. In Python, libraries such as Pandas, NumPy, Matplotlib, and Scikit-learn are commonly used.<\/p>\n
Construct the portfolio based on the HRP model. Calculate the weights of each asset and measure the overall portfolio risk.<\/p>\n
Evaluate the performance based on the backtesting results. Key metrics include the Sharpe ratio, maximum drawdown, and annualized return. These metrics can help verify the effectiveness of the trading strategy.<\/p>\n
This section will show how to implement machine learning-based HRP backtesting in practice. We will proceed step by step with real code examples.<\/p>\n

ML-based trading strategies enhance the efficiency of data analysis and present a new paradigm for risk management. Continuous research and development are needed for successful algorithmic trading, and we hope this leads to better investment outcomes.<\/p>\n
