OneTick© is a software solution for tick data management and market data analytics developed by OneMarketData. It combines a proprietary time series database, real-time complex event processing (CEP) and financial analytics. OneTick provides asset-class neutral market data capture, storage as well as reference data primarily focused on the capital markets industry within finance. OneTick queries can be written using a acyclic directed graph or in standard code (C++, java). Data can be sourced from either real-time markets or historical time series.
