La profondeur de marché est une métrique qui montre la liquidité réelle des marchés. En raison du wash-trading généralisé et de l''activité fictive, le volume n''est actuellement pas l''indicateur le plus fiable dans l''espace crypto.

Elle mesure une section de 1% ou 10% du carnet d''ordres à partir du prix médian (1%/10% des ordres d''achat et 1%/10% des ordres de vente).

C''est important, car mesurer l''ensemble du carnet d''ordres donnerait des résultats faux en raison des valeurs extrêmes, ce qui peut créer une fausse illusion de liquidité pour un marché donné.

By default Market depth is showing the most liquid markets sorted by Combined Orders (which is a sum of buy and sell orders). This way it provides the most interesting information already. Left (green) side of the market depth bar is showing how many buy orders are open, and right (red) side of the bar is showing how many sell orders are open (both can be recalculated to BTC, ETH or any fiat we have available on the site).

Due to rampant malicious practices in the crypto exchanges environment, we have introduced in 2019 and 2020 new ways of evaluating exchanges and one of them is - Confidence. Because it's a new metric - it's essential to know how it works.

• Based on the liquidity from order books (75%) - including overall liquidity and market depth/volume ratio, volumes included, if exchange is low volume (below 2M USD volume 24h)

• Based on web traffic (20%) - using Alexa rank as a main indicator of site popularity

• Based on regulation (5%) - researching and evaluating licensing for exchange - by respective institutions

• Adding all of these subscores give overall main result - Confidence

Confiance is mainly based on liquidity, because it's the most important aspect of cryptocurrency exchanges. Without liquidity there is no trading, illiquid markets tend to collapse in the long term. Besides liquidity - there is also an additional factor in calculation of score - market depth/volume ratio. If volume is huge (especially when it’s growing much faster than liquidity), and market depth seems to not keep pace with - it's reducing overall score. Exchanges that keep market makers liquidity with expanding volume are those that keep all ratios in-tact and have overall score above 75-80% (it means that they have all liquidity ratios above minimum requirements, high web traffic participation, and are often regulated).
