In the ever-evolving financial markets, quantitative trading has transitioned from being an exclusive "mystical weapon" of institutions to becoming accessible to the general public. In the past, building quantitative trading strategies required deep programming expertise, vast data resources, and powerful computational capabilities, which deterred retail investors. However, with the rapid development of AI technologies and the increasing availability of financial data services, retail quantitative trading is now entering a new era. The combination of DeepSeek and the iTick real-time stock quote API for Hong Kong and U.S. markets is becoming a key driver in ushering in the era of universal quantitative trading.
I. Quantitative Trading: From Institutional Exclusivity to Retail Accessibility
Quantitative trading, in simple terms, is a trading method that uses mathematical models and computer programs to guide investment decisions. Institutional investors, leveraging abundant resources, can collect, clean, process, and analyze vast amounts of historical and real-time data, using complex statistical models and machine learning algorithms to uncover market patterns and develop trading strategies. For example, high-frequency trading strategies capture market opportunities at millisecond or even microsecond levels, executing trades quickly to profit from small price differences. Automated trading systems execute trade orders based on preset rules and algorithms, avoiding emotional interference and improving trading efficiency and precision.
Quantitative trading was once the "privilege" of large institutions, but with the proliferation of AI and open APIs, retail investors can now build their own trading systems at low costs. With technological advancements, retail accounts can now apply for quantitative trading API access without barriers, often for free, with trading fees lower than those of regular accounts. Retail investors can embark on their quantitative trading journey by learning financial knowledge, mastering programming languages (such as Python), and choosing suitable quantitative platforms, utilizing the wealth of free learning resources available online.
II. DeepSeek: An Innovator in Artificial Intelligence
DeepSeek is a Chinese AI research lab specializing in developing large language models, with its series of models demonstrating strong capabilities in natural language processing. For instance, DeepSeek-V3 rivals industry-leading models in performance while maintaining relatively low development costs. A standout feature of DeepSeek models is their open-source nature, allowing developers and researchers to freely access, customize, and deploy them in software, significantly lowering the application threshold and promoting the widespread adoption of AI technologies across various fields. In quantitative trading, DeepSeek's large models can convert natural language into code. Investors can simply describe their requirements in Chinese, and the model will automatically generate Python code that meets the standards, greatly reducing programming complexity and enabling investors without deep programming expertise to participate in developing quantitative trading strategies.
