UVXY: This doesn't always mean something, but sometimes it does. Put in a buy order for UVXY 8 calls at the bid and didn't fill at all. Put in a sell order higher up at 15, at the ask and it filled immediately. No one wants to sell calls on UVXY. UVXY could still go down a while until 'big guys' fulfill accumulation if it is significant. Risky trade as it just reached new lows.
