Start with activity, then check depth
A market heatmap is useful because it separates busy markets from actionable markets. Volume tells you where attention is going, while liquidity and spread context tell you whether the displayed price can support a real trade or research signal.
1. Sort by volume windows
Compare 24h, 7d, and category-level volume instead of relying on a single total. Short-window spikes can reveal news-driven repricing before longer-window charts catch up.
2. Treat liquidity as a quality filter
A large move in a thin market may be less useful than a smaller move in a deep market. Use liquidity bands and spread checks to avoid over-reading noisy contracts.
3. Drill into holders
Once a market stands out, inspect top holders and wallet behavior. Concentrated ownership can explain why a price moves quickly or why liquidity disappears.
