I wanted to buy my first bond ever today, but when trying to get the prices for "US Treasuries" in the bond scanner page on Interactive Brokers , I was greeted with the following message: Is this because treasury bonds are "released" by the US government once every so often, trading not being allowed in-between periods, OR is it bad UX from Interactive Brokers' end?
