In recent years, quantitative analysis in the financial field has received more and more attention from the theoretical and practical circles, and the technology of quantitative analysis has also made great progress, becoming a hot spot that has attracted much attention. The so-called financial quantification is the combination of financial analysis theory and computer programming technology, and more effective use of modern computing technology to achieve accurate financial asset pricing and discovery of trading opportunities. Quantitative analysis has involved all aspects of the financial sector, including basic and derivative financial asset pricing, risk management, and quantitative investment. With the development of big data technology, quantitative analysis is also gradually combined with big data to achieve effective and fast calculation and processing of massive financial data.
In the era of quantitative finance, choosing an appropriate programming language is crucial to the realization of financial models. In this regard, the Python language embodies unusual advantages, especially it has a large number of financial computing libraries, and can provide interfaces with C ++, java and other languages to achieve efficient analysis, and has become a rapid development and application in the financial field. A key language, because it is open source, reduces the cost of financial computing, and also provides a large number of application examples through a wide range of social networks, which greatly shortens the learning path of financial quantitative analysis.
This course introduces the relationship between quantitative analysis and the rapid development of Python language, so that students can quickly master the basic methods of quantitative analysis of financial data using Python language.
