talibpython⽂档_TA-Lib中⽂⽂档(⼀):快速开始TA-Lib
简介:
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
包含了炒股150+的数据指标:ADX, MACD, RSI, Stochastic, Bollinger Bands, etc.
K线趋势识别
完全开源,⽀持 C/C++, Java, Perl, Python and 100% Managed .NET
安装TA-Lib
案例(快速开始)
Similar to TA-Lib, the function interface provides a lightweight wrapper of
the exposed TA-Lib indicators.
类似于TA库,对函数接⼝进⾏了⼀个轻量级的封装,⽤于公开的ta-lib的指标。
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)
Abstract API Quick Start
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'])

Supported Indicators ⽀持指标
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
