Keep the analysis evidence-based and explain empty windows.
macOS terminal: Run workshop commands in Terminal using zsh or bash.
Timing
20 minutes.
Talk track
- Probability is the latest quote midpoint with an explicit freshness timestamp.
- A move is less persuasive when the spread is wide or the quote is stale.
- Volume velocity compares adjacent five-minute windows; it is not a forecast.
- Every statement is public-data analysis, not financial advice.
Common failures
- Movers empty before minute five: expected; return after the other queries.
- Fixture prices show regular patterns: label them fixture data.
- A Yes/No pair does not sum to exactly 100: spreads and separate books explain the gap.
Reset
No state change. Re-run the queries after enough time has accumulated.
