　　什么是量化交易？

　　量化交易（Quantitative Trading）是通过数学模型和计算机算法对金融市场进行分析和预测，And based on this,a trading strategy is developed for investment trading.与传统的基本面分析、技术分析等方法不同，Quantitative trading emphasizes the use of a large amount of data and scientific methods for research,reducing the impact of human factors and improving the efficiency and accuracy of trading.

　　量化交易的特征在于，它是一种基于数据和科学方法的交易方式，通常涉及大量数据分析、统计学、计算机科学等知识领域。Compared with traditional trading,quantitative trading uses more sophisticated and efficient trading strategies,which can more quickly obtain market information,analyze Market trend and laws,and make corresponding trading decisions.
