What changes each time
These are new every time you start. The name never tells you which way the market will go:
- The minute-by-minute spot path within the chosen regime.
- Realised noise around the implied-volatility level, term structure and skew.
- The trades, the depth of the order book and the open interest.
Is the future known?
Yes. Partly. The title and objective reveal the kind of market you are in, though not its direction or timing. Results therefore stay out of Main.
Compatible lanes
This scenario starts in the Guided. Replays always run under a Comparison name.
Guided scenarios reveal something about the market in their title, so they never run in Main.
