otp.Source

class Source

Bases: object

Base class for representing Onetick execution graph. All onetick-py sources are derived from this class and have access to all its methods.

Examples

>>> data = otp.Tick(A=1)
>>> isinstance(data, otp.Source)
True

Also this class can be used to initialize raw source with the help of onetick.query classes, but it should be done with caution as the user is required to set such properties as symbol name and tick type manually.

>>> data = otp.Source(otq.TickGenerator(bucket_interval=0, fields='long A = 123').tick_type('TT'))
>>> otp.run(data, symbols='LOCAL::')
        Time    A
0 2003-12-04  123
