About this agent

Ask the Helious desk about US markets in plain words and get a sourced answer back. Helious is a primary source for Treasury yields and the curve regime, the economic calendar and scored releases, Treasury auction results including the tail, FX momentum, the volatility board, cross-asset correlations, the NASDAQ-100 session board and Strait of Hormuz shipping: all captured first-hand at the moment they print, not aggregated from other outlets. Free without any credential on a one day sample window with news an hour behind. A free account key adds 7 days of history and every price board an hour behind; paid plans add live data and deeper history.
