TA-Lib，全稱“Technical Analysis Library”, 即技術(shù)分析庫，是 Python 金融量化的高級庫，涵蓋了 150 多種股票、期貨交易軟件中常用的技術(shù)分析指標(biāo)，如 MACD、RSI、KDJ、動量指標(biāo)、布林帶等等。

你所需要的網(wǎng)站建設(shè)服務(wù)，我們均能行業(yè)靠前的水平為你提供.標(biāo)準(zhǔn)是產(chǎn)品質(zhì)量的保證，主要從事成都網(wǎng)站建設(shè)、成都網(wǎng)站設(shè)計、企業(yè)網(wǎng)站建設(shè)、成都做手機(jī)網(wǎng)站、網(wǎng)頁設(shè)計、成都品牌網(wǎng)站建設(shè)、網(wǎng)頁制作、做網(wǎng)站、建網(wǎng)站。成都創(chuàng)新互聯(lián)擁有實力堅強(qiáng)的技術(shù)研發(fā)團(tuán)隊及素養(yǎng)的視覺設(shè)計專才。

TA-Lib 可分為 10 個子板塊：

• Overlap Studies(重疊指標(biāo))
• Momentum Indicators(動量指標(biāo))
• Volume Indicators(交易量指標(biāo))
• Cycle Indicators(周期指標(biāo))
• Price Transform(價格變換)
• Volatility Indicators(波動率指標(biāo))
• Pattern Recognition(模式識別)
• Statistic Functions(統(tǒng)計函數(shù))
• Math Transform(數(shù)學(xué)變換)
• Math Operators(數(shù)學(xué)運算)

本文介紹通過 Funcraft 的模板將 Python 量化交易庫 TA-lib 移植到函數(shù)計算。

依賴工具

本項目是在 MacOS 下開發(fā)的，涉及到的工具是平臺無關(guān)的，對于 Linux 和 Windows 桌面系統(tǒng)應(yīng)該也同樣適用。在開始本例之前請確保如下工具已經(jīng)正確的安裝，更新到最新版本，并進(jìn)行正確的配置。

• Docker
• Funcraft

對于 MacOS 用戶可以使用 homebrew 進(jìn)行安裝：

brew cask install docker
brew tap vangie/formula
brew install fun

Windows 和 Linux 用戶安裝請參考：

https://github.com/aliyun/fun/blob/master/docs/usage/installation.md

安裝好后，記得先執(zhí)行 fun config 初始化一下配置。

初始化

使用 fun init 命令可以快捷地將本模板項目初始化到本地。

fun init vangie/ta-lib-example

安裝依賴

$ fun install
using template: template.yml
