What does quantitative trading mean?

Quantitative trading refers to the investment method of trading using computer technology with the help of modern statistical and mathematical methods. Quantitative trading can bring a variety of "high probability" events with excess returns from huge historical data to formulate strategies, verify and solidify these laws and strategies with quantitative models, and then strictly implement solidified strategies to guide investment in order to obtain sustainable, stable and higher-average returns.

市場將量化交易分為以下類別：系統(tǒng)化交易、算法交易、程序化交易和機械式交易等，其中前三種模式在市場比較常見。

1.系統(tǒng)化交易指投資者將交易思路量化為交易系統(tǒng)，根據系統(tǒng)指標進行交易；

2.算法交易是利用電子平臺，輸入涉及算法的交易指令，以執(zhí)行預先設定好的交易策略，指令中包含變量，包括時間，價格，交易量等，廣泛應用于大宗交易；

3.程序化交易就是將投資者復雜的交易思路轉變?yōu)槟芎唵尾僮鞯闹悄芙灰紫到y(tǒng)，便于投資者的嚴格執(zhí)行。
