This is a Python wrapper for TA-LIB based on Cythoninstead of SWIG. From the homepage:
TA-Lib is widely used by trading software developers requiring to performtechnical analysis of financial market data.
- Includes 150+ indicators such as ADX, MACD, RSI, Stochastic, BollingerBands, etc.
- Candlestick pattern recognition
- Open-source API for C/C++, Java, Perl, Python and 100% Managed .NET
The original Python bindings included with TA-Lib useSWIG which unfortunately are difficult to install andaren't as efficient as they could be. Therefore this project uses Cython andNumpy to efficiently and cleanly bind to TA-Lib -- producing results 2-4times faster than the SWIG interface.
Installation
You can install from PyPI:
Or checkout the sources and run setup.py yourself:
Troubleshooting
If you get a warning that looks like this:
This typically means setup.py can't find the underlying TA-Liblibrary, a dependency which needs to be installed.
If you installed the underlying TA-Lib library with a custom prefix(e.g., with ./configure --prefix=$PREFIX), then when you go to installthis python wrapper you can specify additional search paths to find thelibrary and include files for the underyling TA-Lib library using theTA_LIBRARY_PATH and TA_INCLUDE_PATH environment variables:
Sometimes installation will produce build errors like this:
or:
This typically means that it can't find the underlying TA-Lib library, adependency which needs to be installed. On Windows, this could be caused byinstalling the 32-bit binary distribution of the underlying TA-Lib library,but trying to use it with 64-bit Python.
Sometimes installation will fail with errors like this:
This typically means that you need the Python headers, and should runsomething like:

It permits you to edit, manage, delete, preview, Associate in Nursingd conjointly build an album. You’ll be able to conjointly manage your pictures on iOS and golem devices.
Sometimes building the underlying TA-Lib library has errors runningmake that look like this:
This might mean that the directory path to the underlying TA-Lib libraryhas spaces in the directory names. Try putting it in a path that does not haveany spaces and trying again.
Dependencies
To use TA-Lib for python, you need to have theTA-Lib already installed. You shouldprobably follow their installation directions for your platform, but somesuggestions are included below for reference.
Mac OS X
Windows
Download ta-lib-0.4.0-msvc.zipand unzip to C:ta-lib.
This is a 32-bit binary release. If you want to use 64-bit Python, you willneed to build a 64-bit version of the library. Some unofficial (andunsupported) instructions for building on 64-bit Windows 10, here forreference:
- Download and Unzip
ta-lib-0.4.0-msvc.zip - Move the Unzipped Folder
ta-libtoC: - Download and Install Visual Studio Community 2015
- Remember to Select
[Visual C++]Feature
- Remember to Select
- Build TA-Lib Library
- From Windows Start Menu, Start
[VS2015 x64 Native Tools Command Prompt] - Move to
C:ta-libcmakecdrwin32msvc - Build the Library
nmake
- From Windows Start Menu, Start
You might also try these unofficial windows binaries for both 32-bit and64-bit:
Linux
Download ta-lib-0.4.0-src.tar.gz and:
If you build TA-Lib using make -jX it will fail but that's OK!Simply rerun make -jX followed by [sudo] make install.
Function API
Similar to TA-Lib, the Function API provides a lightweight wrapper of theexposed TA-Lib indicators.
Each function returns an output array and have default values for theirparameters, unless specified as keyword arguments. Typically, these functionswill have an initial 'lookback' period (a required number of observationsbefore an output is generated) set to NaN. Qbeez 2 for mac.
For convenience, the Function API supports both numpy.ndarray andpandas.Series inputs.
All of the following examples use the Function API:
Calculate a simple moving average of the close prices:
Calculating bollinger bands, with triple exponential moving average:
Calculating momentum of the close prices, with a time period of 5:
Abstract API
If you're already familiar with using the function API, you should feel rightat home using the Abstract API.
Every function takes a collection of named inputs, either a dict ofnumpy.ndarray or pandas.Series, or a pandas.DataFrame. If apandas.DataFrame is provided, the output is returned as apandas.DataFrame with named output columns.
For example, inputs could be provided for the typical 'OHLCV' data:
Functions can either be imported directly or instantiated by name:
From there, calling functions is basically the same as the function API:
Supported Indicators and Functions
We can show all the TA functions supported by TA-Lib, either as a list oras a dict sorted by group (e.g. 'Overlap Studies', 'Momentum Indicators',etc):
Indicator Groups
- Overlap Studies
- Momentum Indicators
- Volume Indicators
- Volatility Indicators
- Price Transform
- Cycle Indicators
- Pattern Recognition
