2020 IEX ARC.IO

This fall, IEX ARC is going virtual.

Last year, the inaugural IEX Academic Research Conference (ARC) brought together market structure researchers and market participants for a day of discussion and ideation around breakthrough equity market structure research – research that is made possible given access to and understanding of market data. This fall, IEX ARC returns... but as “ARC.IO”: an academic conference fully centered on the theme of market data and its importance for academic research.

In part in response to the pandemic, ARC.IO will not be a standard academic conference. First, ARC.IO will be fully virtual. Second, ARC.IO will host presentations that are not necessarily full-fledged research papers. Rather, IEX is hosting talks from market structure researchers to discuss their research experience with market data: how to obtain it, how to handle it, how to understand it, how to use it, or any other aspect of using market data in market structure research. Finally, researchers will also discuss the difficulty of obtaining or working with market data, including potential unsuccessful efforts.

The presentations will last 25 minutes + 5 minutes of Q&A.
