Key number	Its 'unusual' tag compares a trade's size and premium to that contract's normal volume and open interest. It describes the trade, not why it was placed or who placed it.	Labels like 'sweep' mean one order was split across several exchanges at once. That shows urgency of execution, not direction or intent.
