3. Adding Indicators

Technify uses the ta-lib library so the algorithms provided are the ones described in their repository documentation.

from technify import indicators

The indicators can be added by means of the append function, the signature is the same for all of them:

1. the indicator function name
2. list containing the input columns for the indicator
3. map of parameters to overwrite (optional)
4. saveas parameter with a list of column names that will overwrite the default generated columns.

Example:

msft = Stock.fromQuandl("EOD/MSFT")\
        .append(ov.ema, "Open", timeperiod=40)   # stores the result as 'ema'
msft = Stock.fromQuandl("EOD/MSFT")\
        .append(ov.bbands,"Close", saveas=["low", "medium", "high"])  # custom Bollinger bands

The following list contains the available functions in Indicators module:
