Metric UI: Micro acceleration 5min vol / 15min vol Common floor: ≥ 150%

Micro Acceleration (5m / 15m)

Compares 5-minute activity intensity against the 15-minute regime to detect short-horizon bursts.

Definition

#
Measures how much the current 5-minute volume intensity diverges from the 15-minute intensity baseline. It is designed to detect fast short-horizon expansion in activity.

Formula & calculation

#
First compute rolling intensity ratios:
Rolling Intensity Ratio(w) = ((Current Window Volume + Live Volume) / (Historical Mean Volume per Minute × Window Minutes)) × 100
Then compute acceleration:
(5m Rolling Intensity Ratio / 15m Rolling Intensity Ratio) × 100

Units & range

%. 100% means 5m intensity matches 15m intensity.

Interpretation

#
Values above 100% mean the 5-minute window is hotter than the 15-minute regime. Higher values imply faster short-term expansion.

Practical usage

#
Useful for identifying fresh bursts of activity that may not yet be fully reflected in slower windows.

Common mistakes

#

Frequent interpretation traps and misuse patterns to avoid when applying this metric.

  • Using it without a minimum liquidity or notional filter.
  • Treating it as a directional signal when it measures acceleration of activity, not direction.
