High-Frequency Trading，简称HFT，即高频交易，是一种利用自动交易系统在极短的时间内捕捉并从市场微小波动中获利的交易策略。高频交易使用复杂的算法来分析多个市场，并根据市场情况执行订单。

英文释义：High-frequency trading (HFT) is a trading method that uses powerful computer programs to transact a large number of orders in fractions of a second. HFT uses complex algorithms to analyze multiple markets and execute orders based on market conditions.

High-Frequency Trading的特征：

1.HFT都是由计算机自动完成的过程化交易；

2.HFT的交易量巨大；

3.HFT的持仓时间很短，日内交易次数很多；

4.HFT每笔收益率很低，但是总体收益稳定。

HFT优点：

参考双语例句：

Yet the real revolution lies in distributed trading, a new globalized way to do business, being pioneered by the high frequency trading (HFT) community, but increasingly applied by all market participants.

但是真正的变革却在于分布式交易这种新的全球化经商模式，这种模式由高频率交易（HFT）群体倡导使用，但是也正逐渐为所有市场参与者所接受。

Hence we differentiate between High Frequency Traders (HFT), for whom latency is of significant importance and Low Frequency Traders (LFT), for whom the minimization of cost and optimum stability of their market presence are the most important priorities.

对高频交易商而言，时延有着显著的重要性；而对低频交易商而言，尽可能降低成本并使其市场占有率达到最佳稳定性才是最重要的优先事项。

We differentiate between High Frequency Traders (HFT), for whom latency is of significant importance, and Low Frequency Traders (LFT), for whom minimizing cost and optimizing the stability of their market presence are the most important priorities.

我们将高频交易商(HFT)与低频交易商(LFT)区分开来，对高频交易商而言，延迟有着显著的重要性，而对低频交易商而言，尽可能降低成本及优化其市场占有率的稳定性才是最重要的优先事项。
