Color And Direction
- Diverging signals (like imbalance) paint two directions from a neutral center — one color for bid/up pressure, another for ask/down.
- Sequential signals (like spread, volume, or volatility) run light-to-dark for low-to-high.
- The color scale is the signal's visualization mode; it is separate from the threshold an alert uses.
What To Compare
- Direction: whether pressure leans bid-side or ask-side.
- Persistence: whether pressure holds across several cells or flashes once.
- Context: whether price confirms, rejects, or ignores the pressure.
- Extremes: whether the value is unusual relative to the recent distribution.
Clusters Over Cells
A single cell is a data point. The stronger read is usually a cluster — pressure spreading across time on one symbol, or across several symbols at once. Use the map to find the cluster, then the inspector to judge it.
