Definition
#Measures the percentage of total notional volume in the current rolling window that comes from aggressive sell executions.
Formula & calculation
#(Sell Window Volume / Total Window Volume) × 100Units & range
% (0–100).
Interpretation
#Values above 50% mean sell-side volume dominates the current window.
Practical usage
#Useful when confirming whether the active window is being driven primarily by sell-side flow.
Common mistakes
#Frequent interpretation traps and misuse patterns to avoid when applying this metric.
- Reading high sell share without checking whether total volume is meaningful.
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.
