Hi,
I stumbled over this while browsing bond ETFs:
What’s going on with the spike on April 2018?
@mmmmmmrk Incorrectly filtered wrong quotes. We’re currently in the process of switching data vendors & improving our filter mechanisms.
Still, keep in mind that quotes don’t affect execution. Even if you were to place a buy order at that exact time, it would still be executed at the best available price.
