Liquidity is the ability to buy or sell without moving the price sharply. Review spread, depth at several distances, credible volume, fragmentation, order size and withdrawal conditions. Historical volatility does not cap the next move.
Not large-order cost
Orders may disappear
Not current liquidity
Measure depth for your own amount
Twenty-four-hour volume does not describe orders available now. Examine quantities near the displayed price, the spread and several order-book levels. Orders can disappear before execution; a screenshot does not guarantee a price.
Separate price impact from slippage
Price impact is movement caused by your own order; slippage is the gap between expected and actual output as conditions change. A narrow tolerance may cause failure, while a wide one permits an unfavorable execution. Add fees separately.
Compare market and limit orders
A market order seeks execution at available prices. A limit order defines an acceptable price but may fill only partially. To estimate a real exit, quote the full amount and include withdrawal fees; the last traded price is insufficient.
Simulate a realistic exit
The last traded price may reflect a tiny trade. Inspect order book or pool depth, spread and the price impact of an order the size you plan.
- A limit price protects price but may prevent execution.
- Include fees and withdrawal risk at the same time.
Practical case: decision and limits
The last trade at 10 does not mean a whole position can sell at 10. In a hypothetical order book, buying 20 tokens at 10 and 30 at 10.20 costs 506 for 50, averaging 10.12 before fees. Market orders consume available levels; limit orders protect price but may fill only partly. Reported volume is not depth at your intended size.
A concrete verification
Compare full-size and smaller quotes: identify costs related to order size.

Frequently asked questions
What should be checked first?
Depth for the intended size, followed by spread and the practical ability to withdraw the assets.
Why retain a copy of the data?
A snapshot can vanish within seconds; retaining time and sources lets you compare conditions.
When is specialist advice appropriate?
For large orders, thin markets or any transaction likely to create meaningful market impact.
