Overview#

onetick.py is a versatile and efficient Python library designed for handling tick data with ease. It harnesses the power of OneTick, the industry-leading tick analytics technology, to process tick data at unparalleled speeds. This library is tailored both for existing OneTick users, as a Python interface into OneTick, and for new users who seek an intuitive tool for tick data analysis that comes with tick data from 200+ exchanges.

The primary strength of onetick.py lies in its similarity to the popular Python library, Pandas. Users familiar with Pandas find onetick.py easy to learn. In particular, onetick.py users can think in terms of Python expressions, built-ins, and native math operations on tick fields.

onetick.py goes far beyond the functionality that exists in Pandas exposing all of the power of OneTick (decades of development for the capital markets use cases) in a Pandas-like style. Crucially, the Pandas-like syntax is translated into the OneTick query language, executing on the high-performance OneTick tick server engine. In a nutshell, onetick.py combines the ease of use of Python with the performance of OneTick.
