How We Score Liquidity at CryptoExID

What the number on our site means

Every exchange profile on CryptoExID carries a liquidity subscore from 0 to 10. Binance currently holds 9.9, Bybit 9.6, OKX 9.5, down through Gemini at 7.6, CEX.IO at 6.8 and Revolut at 6.6. This number is a considered judgment about execution quality, built from data we checked on a specific dataset date.

It is not a live feed. We do not publish an order-book widget, and we think pretending otherwise would be dishonest. Books change hour to hour; our score ranks venues on their demonstrated, persistent quality.

Input one: observed depth

The backbone of the subscore is depth observed on the venue's major pairs, measured in the standard 0.1% and 2% bands around mid price. We care about absolute dollar size, balance between bid and ask sides, and how depth on the venue's flagship pairs compares to peers on the same trading day.

Depth earns its position because it is expensive to fake. Resting orders can be hit by anyone at any moment, so a padded book puts real capital at risk in a way a spoofed volume ticker never does.

Input two: spread persistence

A snapshot spread flatters everyone. What separates venues is whether the spread stays tight through volatile hours, thin weekend sessions and news spikes. A market maker who pulls quotes at the first sign of movement leaves you with a beautiful average and a terrible fill exactly when you need one.

So we sample spreads across different market conditions rather than trusting a single calm-hour reading. Persistent tightness moves the score; a lucky screenshot does not.

Input three: venue tier

Depth and spread describe today. Venue tier describes resilience: the caliber of market makers on the platform, matching-engine reliability during cascades, and track record under stress. Upbit is a good illustration. It scores 9.1 largely on the strength of extraordinary KRW-pair books, a tier of liquidity that exists almost nowhere else.

Tier also catches manipulation risk. Venues with a history of inflated reporting take a haircut here even when a given day's book looks respectable.

How the subscore feeds the overall rating

In our base model, liquidity contributes 15% of an exchange's overall score, alongside fees, security, asset coverage and the rest. On liquidity-focused pages, where the reader has told us execution is what they care about, we reweight the same subscores so liquidity carries up to 40%.

Same data, different lens. A venue like MEXC with 0.00%/0.05% fees can top a fee-focused view while ranking lower here, and both views are true.

What we will not claim

We will not tell you the depth of a book right now, because we do not know it. We will not convert a subscore into a slippage estimate for your specific order, because that depends on the pair, the hour and the size. Use our score to shortlist venues; use the venue's own live book to plan the trade.
