Price, liquidity, volume, and fees answer different questions. A better research record keeps them separate.
A reference price helps describe a market observation. It does not establish what you will receive for a particular quantity on a particular venue. Keep the asset identity, trading pair, quote time, available liquidity, and stated costs together when comparing information.
Uniswap’s explanation of impact and slippage distinguishes the effect of a trade on price from changes between expectation and execution. A slippage-tolerance setting is not simply another platform fee.
| Measurement | Useful question | Do not confuse it with |
|---|---|---|
| Reference price | What observation or methodology produced this quote? | A guaranteed fill for your desired quantity. |
| Trading volume | How much activity was reported in this time window? | Liquidity currently available for a new order. |
| Price impact | How does trade size affect execution in this market? | The fee charged by a platform. |
| Slippage | How did the actual result differ from the expectation? | A promised or unavoidable fixed charge. |
| Fees | Which amounts were charged, and in which assets? | Every difference between two displayed valuations. |
In a fictional order book, 20 tokens are offered at $10 and another 30 at $11. Buying all 50 against those offers costs $530 before fees, an average of $10.60. The initial $10 price does not apply to the entire quantity. The arithmetic illustrates market depth; it is not a current quote or a recommendation to trade.
Preserve the original expectation when reviewing an outcome. A refreshed quote should not overwrite the record you are comparing against. Distinguish submission, confirmation, and the actual assets received. Read the full liquidity and slippage guide for a more detailed workflow.
