look. considering the size of the usual bars, that really isn’t that far out of the norm. if this is on crypto why are you really surprised about a sudden drop? that happens, frequently.
also, when I mentioned the screenshot not saying enough I didn’t mean it was too small.
what I meant is, we don’t know anything about what you are having “issues” with. and because we can’t see the bottom of the graph we don’t know the timestamp for when the drop happened.
also, before you get into complaining about spreads and premiums. none of what you see is determined by T212.
