How to correctly calculate the market volume for each coin?

Question

PHP

Good day, friends. Each coin has its own liquidity. For Bitcoin, 1 million dollars (~20 coins) in a glass is very small and will not affect the market in any way, but for some altcoin, 1 million dollars in a glass is a huge amount and density (volume).
How to correctly calculate the liquidity of a coin based on the data in the order book? The screenshot shows the volumes (densities) that I need to programmatically calculate. That is, to understand that this volume is significant for this particular coin.

How to do this, having data on the glass, the volume per day, and so on. It only comes to mind: to make handles for each coin volumes that you can focus on. But this is not very convenient, because these volumes can change from time to time and then again you will have to edit the handles.

Please tell me, do you have any thoughts on how to calculate liquidity for each individual coin from the information that can be pulled from the API? Thanks in advance !
