Elliott Waves - trying to ID this correction pattern.

I’m trying to figure what kind of correction pattern is forming here. If the tip of correction wave B was Sept 11, then it would be too low to form a flat (right?). Correct me if i’m wrong but a descending triangle should manifest in a downtrend, not an uptrend (unless perhaps the uptrend has reversed?). Or maybe its the begining of a zigzag pattern as drawn above?

I appreciate all comments/ideas to help figure it out.

Thanks
