Using the workspace
A few practical details.
Can I see recent options trades and sweep flags?
Yes. The ticker flow views show recent contract activity and available sweep, floor, opening, and multi-leg flags. Chart markers can be filtered by premium. Flow requires configured Unusual Whales access; coverage and updates depend on the provider.
How can I compare positioning across symbols?
Compare up to four symbols with expiration filters, or explore a single-symbol matrix by strike and expiration. Switch between Net GEX and changes versus the first recorded or live daily reading. Individual strike–expiration cells provide available call/put contract details.
Can I replay any historical trading day?
Replay needs enabled history recording and available sessions. Historical reconstruction depends on the provider: Theta can support historical intraday GEX reconstruction, while Unusual Whales replay uses sessions previously recorded by the workspace.
Which tools need recorded history or a desktop?
The 3D Surface is a desktop view. Volatility analysis uses recorded surfaces, and day-over-day open-interest analysis needs two recorded days. These tools show unavailable data when the necessary inputs are missing.
What do the positioning levels represent?
They are estimates derived from third-party options data and model assumptions. They are research context, not known dealer books, trade recommendations, or guarantees of future price behavior.
