What the listing says

US Treasury yield curve in one call: 1mo/3mo/6mo/1yr/2yr/5yr/10yr/30yr yields, the 10y-2y and 10y-3mo spreads, and a boolean inversion flag on each -- a classic recession/risk-off signal every macro trader watches. Live from FRED's daily constant-maturity Treasury series. Not ticker-specific. $0.01/call.
