Color Signals for Liquidity
The heatmap paints the order book with colors so you can spot where volume is densest without scanning numbers; thick, bright bands mean strong liquidity, while fading colors warn that a level is losing interest. Watching how those bands stretch or disappear gives advance notice of a potential breakout or collapse.
Using Change to Plan Next Steps
Pair the heatmap with recent price action to see whether the color shifts match the chart—when a wall fades before price moves, assume that level is no longer defended and plan accordingly. The shape of the heatmap also highlights corridors where price can drift before hitting the next significant block.
A heatmap redraws the order book into a grid where colors map to concentration, so instead of scanning rows you can glance and see where demand pools. Darker hues mean more resting volume, and the shape of those bands tells you whether a level will likely bend price.
When you see a long stripe of color running horizontally, expect that zone to behave like an invisible wall: it may slow a breakout or keep a drop from accelerating. Rapid color shifts usually happen when participants move their orders, so those moments often precede short bursts of volatility.
The heatmap also shows when walls fade before the chart moves, which is a quiet sign that a level is losing interest even if price still sits there. That kind of signal is useful for avoiding chasing a move that lacks backup orders.
Whalytics refreshes the heatmap in real time, so watching how the blocks brighten or dim gives you a second-by-second feel for which walls are real and which are thin air. Pair the visuals with the actual order book for the clearest story.
Use the heatmap to line up your expectations with what the book is doing and allow color changes to guide where you look next on the chart.
This is not investment advice; let it be a calm study aid rather than a trading mandate.
