移植 Python 量化交易 TA-Lib 库到函数计算 python

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](https://yq.aliyun.com/go/articleRenderRedirect?url=https%3A%2F%2Fstatistics.functioncompute.com%2F%3Ftitle%3D%25E7%25A7%25BB%25E6%25A4%258D%2520Python%2520%25E9%2587%258F%25E5%258C%2596%25E4%25BA%25A4%25E6%2598%2593%2520TA-Lib%2520%25E5%25BA%2593%25E5%2588%25B0%25E5%2587%25BD%25E6%2595%25B0%25E8%25AE%25A1%25E7%25AE%2597%26amp%3Bauthor%3D%25E5%2580%259A%25E8%25B4%25A4%26amp%3Burl%3Dhttp%253A%252F%252Ffc.console.aliyun.com%252F%253Ffctraceid%253DYXV0aG9yJTNEJUU1JTgwJTlBJUU4JUI0JUE0JTI2dGl0bGUlM0QlRTclQTclQkIlRTYlQTQlOEQlMjBQeXRob24lMjAlRTklODclOEYlRTUlOEMlOTYlRTQlQkElQTQlRTYlOTglOTMlMjBUQS1MaWIlMjAlRTUlQkElOTMlRTUlODglQjAlRTUlODclQkQlRTYlOTUlQjAlRTglQUUlQTElRTclQUUlOTc%253D)。
