Heatmap Missing-Depth Zones in Crypto: What Price Response Adds to the Reading

Some heatmap zones show no depth because the book was thin there — or because the data stopped. Price response is different for each.

Short answer

A missing-depth zone is a band on the heatmap with no visible resting size. It can be a real liquidity gap (price may move through quickly), beyond the depth range collected, or a data gap (disconnection, venue outage). Check which before reading price response: real gaps tend to be crossed fast; collection limits say nothing; data gaps mean the heatmap is silent, not the market.

Measuring the response

Check whether trades continued during the gap, whether other levels were shown, and whether the zone is within the collected depth range. Measure traverse speed only for real thin zones.

Example

Illustrative: an empty band at 59,300–59,500 lasted five minutes, but all levels vanished at once and the tape stopped. It was a reconnect, not a liquidity hole.
