Querying a list of segments

A segment is essentially a categorization of instruments based on their types. The various types of segments that are commonly found at exchanges include cash/equities, futures, options, commodities, and currency. Each segment may have a different operating time. Usually, a broker supports multiple segments within multiple exchanges. This recipe demonstrates how to find the list of segments supported by the broker.

Getting ready

Make sure the instruments object is available in your Python namespace. Refer to the second recipe of this chapter to learn how to set up this object.

How to do it…

Display the segments supported by the broker:

>>> segments = instruments.segment.unique()
>>> print(segments)

You will get the following output:

['BCD-FUT' 'BCD' 'BCD-OPT' 'BSE' 'INDICES' 'CDS-FUT' 'CDS-OPT' 'MCX-FUT' 'MCX-OPT' 'NFO-OPT' 'NFO-FUT' 'NSE']

How it works…

instruments.segment returns a pandas.Series object. Its unique method returns a numpy.ndarray object consisting of unique segments supported by the broker.
