Liquidity Is Exit Capacity
You can see the price. Can you get out at it?
The idea
Liquidity is the ability to trade meaningful size quickly without moving price much; volume alone can be misleading.
In the real world
A token shows high reported volume but has little depth near the current price.
Going deeper
Volume records trades that happened; depth describes what your order would meet. They diverge badly because volume can be inflated by wash trading, market-maker churn and bots trading with each other, none of which will absorb your sell.
The number that matters is how much size sits within a few percent of the current price. A token showing $40M of daily volume with $9,000 of depth near the price cannot absorb a $50,000 exit without moving substantially. Checking depth takes seconds and is the difference between a position's quoted value and its realisable one.
Where it stops applying
Depth is a snapshot and can vanish precisely when it is needed, as market makers widen or withdraw under stress. A comfortable book in calm conditions is not a guarantee of one in a selloff.
Why it matters
It reframes a holding from what it is quoted at to what you could realise, which are different numbers.

Test yourself
A token reports $40M of daily volume, but the order book holds only $9,000 within 2% of the price. Which figure describes your ability to sell a $50,000 position?
Show the answer
The book depth. Volume is a record of trades that happened, and can be inflated by wash trading or churn between bots. Depth near the current price is what your own sell would actually consume.
