Technical Analysis Library in Python
It is a Technical Analysis library to financial time series datasets (open, close, high, low, volume). You can use it to do feature engineering from financial datasets. It is built on Pandas and Numpy.
The library has implemented 34 indicators:
- Accumulation/Distribution Index (ADI)
- On-Balance Volume (OBV)
- Chaikin Money Flow (CMF)
- Force Index (FI)
- Ease of Movement (EoM, EMV)
- Volume-price Trend (VPT)
- Negative Volume Index (NVI)
- Volume Weighted Average Price (VWAP)
- Average True Range (ATR)
- Bollinger Bands (BB)
- Keltner Channel (KC)
- Donchian Channel (DC)
- Moving Average Convergence Divergence (MACD)
- Average Directional Movement Index (ADX)
- Vortex Indicator (VI)
- Trix (TRIX)
- Mass Index (MI)
- Commodity Channel Index (CCI)
- Detrended Price Oscillator (DPO)
- KST Oscillator (KST)
- Ichimoku Kinkō Hyō (Ichimoku)
- Parabolic Stop And Reverse (Parabolic SAR)
- Money Flow Index (MFI)
- Relative Strength Index (RSI)
- True strength index (TSI)
- Ultimate Oscillator (UO)
- Stochastic Oscillator (SR)
- Williams %R (WR)
- Awesome Oscillator (AO)
- Kaufman's Adaptive Moving Average (KAMA)
- Rate of Change (ROC)
- Daily Return (DR)
- Daily Log Return (DLR)
- Cumulative Return (CR)
Motivation to use
How to use (Python 3)
$ pip install --upgrade ta
To use this library you should have a financial time series dataset including
You should clean or fill NaN values in your dataset before add technical analysis features.
You can get code examples in examples_to_use folder.
You can visualize the features in this notebook.
Example adding all features
import pandas as pd from ta import add_all_ta_features from ta.utils import dropna # Load datas df = pd.read_csv('ta/tests/data/datas.csv', sep=',') # Clean NaN values df = dropna(df) # Add all ta features df = add_all_ta_features( df, open="Open", high="High", low="Low", close="Close", volume="Volume_BTC")
Example adding particular feature
import pandas as pd from ta.utils import dropna from ta.volatility import BollingerBands # Load datas df = pd.read_csv('ta/tests/data/datas.csv', sep=',') # Clean NaN values df = dropna(df) # Initialize Bollinger Bands Indicator indicator_bb = BollingerBands(close=df["Close"], n=20, ndev=2) # Add Bollinger Bands features df['bb_bbm'] = indicator_bb.bollinger_mavg() df['bb_bbh'] = indicator_bb.bollinger_hband() df['bb_bbl'] = indicator_bb.bollinger_lband() # Add Bollinger Band high indicator df['bb_bbhi'] = indicator_bb.bollinger_hband_indicator() # Add Bollinger Band low indicator df['bb_bbli'] = indicator_bb.bollinger_lband_indicator() # Add Width Size Bollinger Bands df['bb_bbw'] = indicator_bb.bollinger_wband() # Add Percentage Bollinger Bands df['bb_bbp'] = indicator_bb.bollinger_pband()
Deploy and develop (for developers)
$ git clone https://github.com/bukosabino/ta.git $ cd ta $ pip install -r play-requirements.txt $ make test
Thank you to OpenSistemas! It is because of your contribution that I am able to continue the development of this open source library.
- Automated tests for all the indicators.
- Add more technical analysis features.
- Wrapper to get financial data.
- Use of the Pandas multi-indexing techniques to calculate several indicators at the same time.
- use Plotly/Streamlit to visualize features
