Real time callback different than historical quotes?

This can’t be accurate during market hours…

I’m trying to move my algos over to Alpaca and one went rogue during testing. I noticed the same thing as you. I’m wondering if this would be fixed by subscribe_trades rather than subscribe_quotes. But regardless, does this mean Alpaca is quoting 27.5 point spread on BRK.B? That should be a highly liquid stock with very minimal spread.
