I’m trying to understand what happened here from a market microstructure perspective.

During the final minute on June 26, Thinkorswim shows dozens of trades repeatedly printing around 716 even though SPY was actually trading near 731.

Rather than speculate, I’m curious what these actually represent on the tape.
Specifically:
Are these genuine executions?
Off-market reports?
Corrected trades?
Something excluded from price formation?
If someone has CTA condition codes or direct-feed data I’d love to know how these prints were classified.
My guess would have been late reported or corrected trades.
