# Introduction

Display Groups function allows API clients to integrate with [TWS Color Grouping Windows](https://www.ibkrguides.com/tws/usersguidebook/specializedorderentry/use_windows_grouping_to_link_blotter.htm).

TWS Color Grouping Windows are identified by a colored chain in TWS and by an integer number via the API. Currently that number ranges from 1 to 7 and are mapped to specific colors, as indicated in TWS.
