Definition
#Measures how often one-minute notional volume exceeds $50,000 over the last 24 hours. Each completed minute contributes equally, regardless of how far its volume exceeds the threshold. The current unfinished minute is excluded; missing minutes do not qualify.
Formula & calculation
#floor(100 × qualifying minutes / 1,440). A minute qualifies only when its total notional volume (sum of price × quantity across its trades) is strictly greater than $50,000. The denominator stays at 1,440 even with less history, and the rolling window does not reset at midnight.
Units & range
0–100 (whole-number percentage, rounded down).
Interpretation
#100 means all 1,440 completed minutes exceeded $50,000. A score of 50 means at least half qualified. Minutes at or below $50,000 contribute zero, even if they contain trades.
Practical usage
#Set a minimum score to select markets that consistently exceed $50,000 in one-minute notional volume. A minimum score of 80 requires at least 1,152 qualifying minutes in the last 24 hours. Pair it with Today Volume to compare that consistency with total traded notional.
Common mistakes
#Frequent interpretation traps and misuse patterns to avoid when applying this metric.
- Assuming a high score means low volatility or tight spreads.
- Reading a low score as no trading: minutes at or below $50,000 do not qualify.
