From TA-LIB's homepage:
TA-Lib is widely used by trading software developers requiring to perform technical analysis of financial market data.
- Includes 200 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
Unfortunately, the included Python bindings use SWIG, are a little difficult to install (particularly on Mac OS X), and aren't as efficient as they could be. This project uses Cython and Numpy to efficiently and cleanly bind to TA-Lib -- producing results 2-4 times faster than the SWIG interface.
You can install from PyPI:
$ easy_install TA-Lib
Or checkout the sources and run setup.py yourself:
$ python setup.py install
Note: this requires that you have already installed the ta-lib library
on your computer (you can download it or
use your computers package manager to install it, e.g.,
brew install ta-lib on Mac OS X).
Similar to TA-Lib, the functions return an index into the input where the output data begins and have default values for their parameters, unless specifed as keyword arguments.
All of the following examples will use these definitions:
import numpy
import talib
data = numpy.random.random(100)Calculate a simple moving average:
output = talib.SMA(data)Calculating bollinger bands, with triple exponential moving average:
upper, middle, lower = talib.BBANDS(data, matype=talib.MA_T3)Calculating momentum, with a time period of 5:
output = talib.MOM(data, timeperiod=5)Some of the included indicators:
