Definition
#Measures how aggressive sell notional volume in the active rolling window compares with the historical average sell volume for that same window.
Formula & calculation
#(Current Sell Window Volume / Historical Avg Sell Window Volume) × 100Units & range
%.
Interpretation
#Higher values indicate sell-side notional flow is running above its normal pace.
Practical usage
#Useful for identifying unusual sell-side expansion relative to history.
Common mistakes
#Frequent interpretation traps and misuse patterns to avoid when applying this metric.
- Treating it as a stand-alone signal without checking the opposing side.
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.
