Talib一直缺乏有效的中文文档，自己又有空闲时间，且在研究量化对冲系统，就发点时间，做一下翻译。 原文地址： TA-LIB document 翻译地址：
这是一个Python 金融指数处理库TA-LIB，他是基于 Cython 而不是 SWIG。
TA-Lib is widely used by trading software developers requiring to perform technical analysis of financial market data.
TA-Lib广泛应用与交易软件，和金融市场数据进行技术分析。
- Includes 150+ indicators such as ADX, MACD, RSI, Stochastic, Bollinger Bands, etc.
- Candlestick pattern recognition
- Open-source API for C/C++, Java, Perl, Python and 100% Managed .NET
- 包含了150多个指标,包括：ADX, MACD, RSI, Stochastic, Bollinger Bands, 等.
- K线形态识别
- 完全开源，支持 C/C++, Java, Perl, Python and 100% Managed .NET
Similar to TA-Lib, the function interface provides a lightweight wrapper of
the exposed TA-Lib indicators.
类似于TA-Lib，函数接口提供了一个暴露TA-Lib指标的轻量级封装。
Each function returns an output array and have default values for their
parameters, unless specified as keyword arguments. Typically, these functions
will have an initial "lookback" period (a required number of observations
before an output is generated) set to NaN.
每个函数都默认需要输入数组，并为它们提供默认值。
参数，除非指定为关键字参数。通常，这些函数
会有一个初步的“lookback”时期（观测所需数量
在生成一个输出之前），设置为“NaN”。
All of the following examples use the function API:
所有的API函数的使用，都需引入库文件：
import numpy
import talib
close = numpy.random.random(100)计算收盘价的一个简单移动平均数SMA:
output = talib.SMA(close)计算布林线，三指数移动平均：
from talib import MA_Type
upper, middle, lower = talib.BBANDS(close, matype=MA_Type.T3)计算收盘价的动量，时间为5：
output = talib.MOM(close, timeperiod=5)If you're already familiar with using the function API, you should feel right
at home using the abstract API. Every function takes the same input, passed
as a dictionary of Numpy arrays:
如果您已经熟悉使用函数API，那么您就应该精通使用抽象API。
每个函数有相同的输入，作为一个字典通过NumPy数组：
import numpy as np
# note that all ndarrays must be the same length!
inputs = {
'open': np.random.random(100),
'high': np.random.random(100),
'low': np.random.random(100),
'close': np.random.random(100),
'volume': np.random.random(100)
}函数可以直接导入，也可以用名称实例化：
from talib import abstract
sma = abstract.SMA
sma = abstract.Function('sma')调用函数基本上与函数API相同：
from talib.abstract import *
output = SMA(input_arrays, timeperiod=25) # SMA均线价格计算收盘价
output = SMA(input_arrays, timeperiod=25, price='open') # SMA均线价格计算收盘价
upper, middle, lower = BBANDS(input_arrays, 20, 2, 2)
slowk, slowd = STOCH(input_arrays, 5, 3, 0, 3, 0) # uses high, low, close by default
slowk, slowd = STOCH(input_arrays, 5, 3, 0, 3, 0, prices=['high', 'low', 'open'])了解更多高级使用TA库 here.
We can show all the TA functions supported by TA-Lib, either as a list or
as a dict sorted by group (e.g. "Overlap Studies", "Momentum Indicators",
etc):
我们可以显示Ta lib的所有TA函数,返回一个 list 或者 dict
