统计套利是通过对历史数据的记录、统计和分析得出的价格规律，用来描述数据

Statistical arbitrage is the price law derived from the recording, statistics and analysis of historical data. It is used to describe the basic characteristics of data such as average value, variance, volatility, etc., and then use the knowledge of probability theory and mathematical statistics to obtain deviations from normal price movement Abnormal situations beyond the level, and use them as the basis for arbitrage. Statistical arbitrage analyzes the relationship between different varieties and finds a suitable area for their relationship, and the range deviating from this area is the arbitrage space. In the research process, the determination of the arbitrage area is affected to some extent by historical data or the arbitrageur ’s subjective judgment. The future uncertainty and unpredictability also pose a great challenge to this theory.

Statistical arbitrage analyzes the relationshipbetween between different species and finds the right region for their relationship, whereas the range away from the area is arbitrage space. In the course of research, the determination of arbitrage area is influenced to some extent by historical data or the subjective judgment of arbitragers, and the uncertainty and unpredictability of the future also pose great challenges to this theory.

Statistical arbitrage analysis of the relationship between different varieties to find a suitable region for their relationship, and the scope of deviation from the region is the arbitrage space. In the research process, the determination of arbitrage area is affected to some extent by historical data or subjective judgment of arbitrager.
