FinTA (Financial Technical Analysis)

Common financial technical indicators implemented in Pandas.

This is work in progress, bugs are expected and results of indicators might not be correct.

Supported indicators:

['SMA', 'SMM', 'EMA', 'DEMA', 'TEMA', 'TRIMA', 'TRIX', 'AMA', 'LWMA', 'VAMA', 'VIDYA', 'ER', 'KAMA', 'ZLEMA', 'WMA', 'HMA', 'VWAP', 'SMMA', 'ALMA', 'MAMA', 'FRAMA', 'MACD', 'PPO', 'VW_MACD', 'MOM', 'ROC', 'RSI', 'IFT_RSI', 'SWI', 'TR', 'ATR', 'SAR', 'BBANDS', 'BBWIDTH', 'PERCENT_B', 'KC', 'DO', 'DMI', 'ADX', 'PIVOTS', 'STOCH', 'STOCHD', 'STOCHRSI', 'WILLIAMS', 'UO', 'AO', 'MI', 'VORTEX', 'KST', 'TSI', 'TP', 'ADL', 'CHAIKIN', 'MFI', 'OBV', 'WOBV', 'VZO', 'EFI', 'CFI', 'EBBP', 'EMV', 'CCI', 'COPP', 'BASP', 'BASPN', 'CMO', 'CHANDELIER', 'QSTICK', 'TMF', 'WTO', 'FISH', 'ICHIMOKU', 'APZ', 'VR', 'SQZMI', 'VPT', 'FVE', 'VFI']

Dependencies:

• python (3.4+)
• pandas (0.21.1+)

TA class is very well documented and there should be no trouble exploring it and using with your data. Each class method expects proper ohlc data as input.

Install:

pip install finta

or latest development version:

pip install git+git://github.com/peerchemist/finta.git

Import

from finta import TA

Prepare data to use with Finta:

finta expects properly formated ohlc DataFrame, with column names in lowercase: ["open", "high", "low", close"] and ["volume"] for indicators that expect ohlcv input.

To prepare the DataFrame into ohlc format you can do something as following:

df.columns = ["date", 'close', 'volume'] # standardize column names of your source

df.set_index('date', inplace=True) # set index on the date column, which is requirement to sort it by time periods

ohlc = df["close"].resample("24h").ohlc() # select only price column, resample by time period and return daily ohlc (you can choose different time period)

ohlc() method applied on the Series above will automatically format the dataframe in format expected by the library so resulting ohlc Series is ready to use.

Examples:

TA.SMA(ohlc, 42) ## will return Pandas Series object with Simple moving average for 42 periods

TA.AO(ohlc) ## will return Pandas Series object with "Awesome oscillator" values

TA.OBV(ohlc) ## expects ["volume"] column as input

TA.BBANDS(ohlc) ## will return Series with Bollinger Bands columns [BB_UPPER, BB_LOWER, BB_MIDDLE]

TA.BBANDS(ohlc, TA.KAMA(ohlc, 20)) ## will return Series with calculated BBANDS values but will use KAMA instead of MA for calculation, other types of Moving Averages are allowed as well.
