stock_chart_tools

Python module for calculating stock charts using yfinance and pandas.

NAME

stock_chart_tools

DESCRIPTION

Functions to create data series for some technical indicators,
which could be charted using various charting tools

    SMA  - Simple moving average
    EMA  - Exponential moving average
    MACD - Moving average convergence divergence
    OBV  - On balance volume
    SSO  - Slow stochastic Oscillator

FUNCTIONS

EMA(data_series, periods)
    Calculate the exponential moving average 
    
    data_series -> pandas Series
    periods     -> the number of periods used to calculate
    
    Example:
        stock_data = get_historical_data(symbol)
        three_day_ema = EMA(stock_data['Close'],3)

MACD(data_series, long_period=26, short_period=12, signal=9)
    Calculates the MACD (Moving Average Convergence Divergence)

    long_period  -> the number of periods for the long window
    short_period -> the number of periods for the short window
    signal       -> the number of periods to use for the signal line
    
    Example:
        stock_data = get_historical_data(symbol)
        macd = MACD(stock_data['Adj Close'])

OBV(close_series, volume_series, days=60)
    Calculates the On Balance Volume
    
    close_series  -> pandas Series with the closing price data
    volume_series -> pandas Series with the volume data
    days          -> number of days to use to calculate
    
    Example:
        stock_data = get_historical_data(symbol)
        obv_data = OBV(stock_data['Adj Close'],stock_data['Volume'])

SMA(data_series, periods)
    Calculate the simple moving average

    data_series -> pandas Series
    periods     -> the number of periods used to calculate
    
    Example:
        stock_data = get_historical_data(symbol)
        three_day_sma = SMA(stock_data['Volume'],3)

SSO(close_series, high_series, low_series, period=14, k=3, d=3)
    Calculates the Slow Stochastic Oscillator
    
    period -> the number of periods for fast %K 
    k      -> the number of periods for %K
    d      -> the number of periods for %D
    
    Example:
        stock_data = get_historical_data(symbol)
        slow_stochastics = SSO(stock_data['Close'])

get_historical_data(symbol, days=365)
    Get historical stock data using the yfinance module

    symbol -> ticker symbol
    days   -> number of *calendar* days of data to fetch

    The end date is the current date.

    Example:
        stock_data = get_historical_data(symbol)
        quarter_data = get_historical_data(symbol,90)

get_historical_data_range(symbol, start_date, end_date)
    Get historical stock data using the yfinance module
    
    symbol     -> ticker symbol
    start_date -> python datetime object for the start of the series
    end_date   -> python datetime object for the end of the series
    
    Example:
        stock_data = get_historical_data_range(symbol,start_date,end_date)
