What Liquidity Means When Someone Quotes You a Number

Liquidity gets quoted as a number and experienced as a result, and the two often disagree. Here is why.

What the screen shows

An exchange displays orders waiting at each price. That looks like available supply.

It overstates it, for two reasons. A lot of it is placed by professionals who withdraw when things get volatile, which is exactly when you want to trade. And the same money sometimes appears on several exchanges at once, so it is counted more than once. If any of this seems abstract, an OTC crypto desk shows the same thing with actual figures attached.

Treat the screen figure as the most that could be there, not as a measurement.

What actually fills

Reliably less than what was shown, and the gap widens when prices are moving.

You can measure it. Trade a known amount, then compare the average price you got against the price when you pressed the button. That difference is the real cost.

Do that at a few different sizes and you have a proper picture for that venue and that asset. It takes an afternoon and it replaces guessing with a number.

What is available to you specifically

What a provider will actually show you depends on your size, your history and whether they know you.

A provider quotes a familiar counterparty differently from an unknown one. That is not favouritism, it is pricing risk.

So liquidity is not just a property of the market. It is a property of the market and your position in it.

Where a provider gets it from

When someone quotes you a firm price for a large amount, they are sourcing it somewhere: their own holdings, another client wanting the opposite, an exchange, or another provider. If you are the one being paid rather than paying, a platform built for institutional allocations handles the same problem in reverse.

The best price usually comes from someone who can match you against another client. Nothing moves in the public market, so the margin can be tighter.

That is why providers with a lot of varied business quote better, and it is a fair question to ask them.

Questions worth asking

What size will you quote without hesitating in this asset. A specific number means they know their position. Vagueness means they will find out when you ask.

What is your usual margin for that size. Again, a number.

What happens when the market is turbulent. Everyone widens. The useful answer says by how much and whether they keep quoting at all.

What to do with the answers

Match the provider to the trade, and have two relationships rather than one, so that a provider pulling back does not leave you unable to act.

And keep your own record: the implied margin on every trade, by provider and size. After twenty trades you will know which is genuinely better for what, which is information no brochure will give you. Check the country list first. a regulated European crypto platform publishes coverage, and it is narrower than most people assume.
