MyTT
MyTT是您量化工具箱里的瑞士军刀,精炼而高效,它将通达信,同花顺,文华麦语言等指标公式indicators,最简移植到Python中,核心库单个文件,仅百行代码,实现和转换同花顺通达信所有常见指标MACD,RSI,BOLL,ATR,KDJ,CCI,PSY等,全部基于numpy和pandas的函数封装,简洁且高性能,能非常方便的应用在各自股票股市技术分析,股票自动程序化交易,数字货币BTC等量化等领域
功能特点
- 核心库轻量化: 项目库就一个文件MyTT.py,不用安装,不用设置,随用随走 ( from MyTT import * 即可 )
- 代码人类化:) 没有什么炫耀的编程花样,初学者也能看懂,自己就能自行增加指标,马上就能用在项目中。
- 不需要安装ta-lib库,是纯python代码实现的的核心逻辑,很多人都有安装ta-lib库的痛苦经历
- 和通达信,同花顺的指标写法完全兼容,一个新的指标基本不用做修改,直接拿来即可使用
- 超高性能,基本不用循环,全是靠numpy,pandas的内置函数实现各种指标
- 和Talib库一样是多天参数进,多天指标出(序列进,序列出),便于画图和观察趋势
- MyTT实现的各种指标和通达信,同花顺,雪球等软件的技术指标一致到小数点后2位
先看一个最简单的例子
