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。
