TA-Lib全称“Technical Analysis Library”, 即技术分析库，是 Python 金融量化的高级库，涵盖了 150 多种股票、期货交易软件中常用的技术分析指标，如 MACD、RSI、KDJ、动量指标、布林带等等。

TA-Lib 可分为 10 个子板块：

Overlap Studies(重叠指标)
Momentum Indicators(动量指标)
Volume Indicators(交易量指标)
Cycle Indicators(周期指标)
Price Transform(价格变换)
Volatility Indicators(波动率指标)
Pattern Recognition(模式识别)
Statistic Functions(统计函数)
Math Transform(数学变换)
Math Operators(数学运算)

本文介绍通过 Funcraft 的模板将 Python 量化交易库 TA-lib 移植到函数计算。
