Definition
#Measures the rarity of the current total number of executions in the active rolling window relative to its historical baseline.
Formula & calculation
#(Live Mean Total Trades - Historical Mean Total Trades) / Historical StdDev Total TradesUnits & range
Z.
Interpretation
#Higher values indicate execution count is statistically elevated relative to normal conditions.
Practical usage
#Useful for spotting unusually busy windows in terms of count rather than size.
Common mistakes
#Frequent interpretation traps and misuse patterns to avoid when applying this metric.
- Equating more trades with larger trades.
Timeframe note
#This metric applies to rolling windows such as 5m, 15m, and 60m. The underlying definition stays the same; what changes is the time horizon used to measure it. Shorter windows react faster, while longer windows smooth noise and emphasize broader structure.
5m
Faster response to fresh changes in activity and short-horizon structure.
15m
Balanced view between responsiveness and persistence.
60m
Broader context that is slower but more stable.
