High frequency trading (HFT) is a kind of algorithmic trading which implements several strategies that result in a high number of intraday messages that are sent to exchanges and other trading venues. High frequency traders (HFTs) are key players in secondary markets given the number of orders and trades they generate. In this text, we explore the boundaries of this phenomenon and the associated risks. We investigate the regulation goals, the mechanisms to achieve such goals and the obstacles ahead. Then we evaluate whether it is necessary to create new rules or update the existing ones in Brazilian law – and what these new rules could be. The formulation of regulatory responses start with the analysis of a theoretical framework for the dynamics of capital markets, its economic functions and how Law can play a key part in this scenario. A critical study of HFTs enables us to assess its risks along with the risks of algorithmic trading in general, and, in addition, it is an invitation to rethinking how the market works, the goals that regulation can pursue and how they can be achieved. Understanding new technologies that emerge in capital markets is paramount before any risk assessment discussions in order to prevent hype and panic. This work also aims to provide an up to date description of the secondary market dynamics and how state-of-art trading technologies reshaped it.
