Introduction to Statistical Arbitrage Statistical Arbitrage is a trading method that captures price mismatch in the financial market based on mathematical models. Its core philosophy stems from mean regression, that is, asset prices may deviate from long-term trends in the short term, but will eventually return to their historical average. Traders use statistical methods to analyze the correlation between assets and look for portfolios that usually change synchronously. When the price relationship of these assets is abnormally deviated, arbitrage opportunities arise. In the cryptocurrency market, statistical arbitrage is particularly prevalent, mainly due to the inefficiency and drastic fluctuations of the market itself. Unlike traditional financial markets, cryptocurrencies operate around the clock and their prices are highly susceptible to breaking news, social media sentiment and technology upgrades. This constant price fluctuation frequently creates pricing bias and provides arbitrageurs with

The recommended way to read files line by line in Python is to use withopen() and for loops. 1. Use withopen('example.txt','r',encoding='utf-8')asfile: to ensure safe closing of files; 2. Use forlineinfile: to realize line-by-line reading, memory-friendly; 3. Use line.strip() to remove line-by-line characters and whitespace characters; 4. Specify encoding='utf-8' to prevent encoding errors; other techniques include skipping blank lines, reading N lines before, getting line numbers and processing lines according to conditions, and always avoiding manual opening without closing. This method is complete and efficient, suitable for large file processing

modprobe is the core tool in Linux for loading, uninstalling and managing kernel modules. It can automatically handle module dependencies. 1. Use the command sudomodprobemodule_name to load the module. For example, sudomodprobenfs will automatically load nfs and its dependencies such as sunrpc. 2. Use sudomodprobe-rmodule_name to uninstall the module. For example, sudomodprobe-rnfs will remove nfs and unused dependent modules, provided that the module is not occupied. 3. Check the module status by lsmod|grepmodule_name to check whether it has been loaded, and use modinfomodulu to
