1. Map the wall
Note the level and whether it is isolated or part of a larger stacked area. One bright band can matter less than a broad zone that keeps rebuilding.
BTC Heatmap and DOM
Passive liquidity is context, not proof.
A heatmap shows where liquidity was resting. The DOM shows the current ladder around price. Both are useful only if you compare them with executed trades, spread behavior and the actual reaction when price reaches the level.
How to read liquidity without overfitting
The main mistake is treating every bright wall as a guaranteed reversal. A wall that gets pulled, stepped through or absorbed is not support or resistance in any reliable sense.
2. Wait for the test
Price reaction is the key. If price touches the wall and aggressive flow fails to continue through it, the level becomes useful. If price cuts through cleanly, the wall was mostly noise.
3. Check the DOM
The ladder helps you inspect the local spread and nearby book shape. It is strongest for immediate context, not for long-horizon prediction on its own.
What CryptoFlow’s heatmap and DOM are for
In production, the heatmap and DOM are designed to support the footprint view, not replace it. Use them to understand why a move stalled or accelerated.
Good use
- Confirming whether a footprint push is running into visible liquidity
- Watching if a wall holds, refreshes or disappears
- Checking spread quality around the current price
- Using DOM as short-range context around a decision point
Bad use
- Buying or selling only because one wall appeared
- Ignoring executed volume after the level is hit
- Reading passive liquidity as if it were already filled volume
- Trusting a single DOM snapshot without structure context
FAQ
What is the difference between a heatmap and the footprint?
The heatmap shows resting liquidity. The footprint shows executed trades. One is intent or displayed supply/demand; the other is what actually traded.
Can a visible wall be fake?
Yes. It can be pulled before the touch or refreshed in a way that changes the story. That is why reaction matters more than the wall’s first appearance.
Should I use DOM on mobile?
Only for quick context. On smaller screens it is better to rely on the chart first and use the DOM as a narrow confirmation tool.
See passive liquidity in the actual chart.
Use the heatmap and DOM to qualify the move, not to predict it in isolation.
