How do I calculate my liquidity?

Excuse me, could you please explain how one goes about calculating their liquidity in the context of cryptocurrency and finance? I understand that liquidity is a crucial aspect of trading, but I'm a bit unsure of the specific steps or formulas involved in determining my own liquidity position. Is there a standard method that professionals in the field tend to use, or does it vary depending on individual circumstances? I'd appreciate any guidance you can offer on this matter.
