Change frequencyHow often a prompt shows a meaningful difference across the recent sampled snapshots. Higher values usually mean a more active or less stable prompt.
Spread movementWhether the prompt spread has been tightening, stable, or widening over the recent sample. Widening is usually a caution sign.
Depth movementWhether cumulative visible depth appears to be increasing, stable, or decreasing. Falling depth often means a less resilient visible book.
Stability cueA first-pass label for whether the prompt looks stable, active, or jumpy in the recent sample. This is an operational monitoring signal, not a precise statistical regime model.
Improving / deterioratingImproving prompts typically show tighter spreads and/or stronger visible depth. Deteriorating prompts typically show wider spreads and/or weaker visible depth.
Recent sample limitationThis page uses a recent snapshot window for first-pass behavior estimates. It is useful for short-horizon monitoring, but not yet a full long-run resilience model.
