Liquidity & price impact

What a gap between liquidity ranges means for a swap quote

Interpret a sparse or empty interval between liquidity ranges without assuming every pool or router handles it identically.

A liquidity gap means the distribution has little or no active capacity over a particular price interval. It can cause a large price movement between regions of available liquidity. The result for a proposed swap depends on the pool implementation, later ranges and the transaction's price or output limits.

Distinguish a thin range from an empty one

In a hypothetical distribution, one dense region ends near price 1.01 and another begins near 1.05. A chart that shows little depth between them warns that continuing in that direction may reach materially different prices before substantial additional output becomes available.

A sparse range still contains capacity with steep price movement. An actually empty interval is a different state. Coarse chart bins or stale data can blur that distinction.

Do not infer the transaction outcome from a picture

Uniswap v3 describes execution through discrete liquidity ranges. A router may reject an unattractive quote, choose another pool, hit a price limit or otherwise stop before satisfying the requested trade. The chart alone does not establish which outcome applies.

Obtain a quote for the actual size and inspect whether it completes the requested quantity under the encoded constraints. A nonzero total pool balance is not sufficient evidence of continuous liquidity at acceptable prices.

Inspect the direction and displayed window

A gap on the other side of the current price may not affect your immediate trade. A gap outside a cropped window may affect a larger trade even when the visible region looks dense.

Record pool identity, state, quote size and the relevant price interval. When describing the problem, say whether the evidence is a missing quote, poor output, a transaction constraint or a chart-based warning. This distinction prevents a useful depth observation from becoming an unsupported claim that the token can never be swapped or that a particular transaction must revert.
