  量化交易就是以數(shù)學(xué)公式和統(tǒng)計(jì)數(shù)據(jù)等為基礎(chǔ)來(lái)建立數(shù)學(xué)模型,通過(guò)數(shù)學(xué)模型來(lái)進(jìn)行交易。


  量化交易依托的是現(xiàn)在高度發(fā)達(dá)的計(jì)算機(jī)技術(shù)和互聯(lián)網(wǎng)技術(shù)。


  量化交易通過(guò)數(shù)學(xué)模型來(lái)代替人工交易,It can effectively avoid the subjective judgment of investors,which is the impact of investor sentiment fluctuations.Avoid making irrational decisions in extreme fanaticism or pessimism.


  量化交易需要以大量的數(shù)據(jù)作為基礎(chǔ),通過(guò)對(duì)大量數(shù)據(jù)的分析,來(lái)做出理性的判斷,預(yù)測(cè)未來(lái)價(jià)格的走勢(shì)。
