What is Liquidity?

Liquidity refers to how easily you can buy or sell an asset without causing significant price movement. A highly liquid market has many buyers and sellers, allowing large trades to execute at stable prices.

Why Liquidity Matters

For Traders

  • Better price execution
  • Lower slippage
  • Faster order fills
  • Easier to enter/exit positions

For Markets

  • Price stability
  • Fair price discovery
  • Market efficiency
  • Attracts more participants

Measuring Liquidity

Trading Volume

  • 24-hour volume
  • Higher = more liquid
  • Compare across exchanges

Order Book Depth

  • Bids and asks at each price
  • Deep books = better liquidity
  • Check multiple price levels

Bid-Ask Spread

  • Difference between best bid and ask
  • Tight spread = high liquidity
  • Wide spread = low liquidity

Liquidity Examples

High Liquidity

Bitcoin on Binance:

  • Billions in daily volume
  • Tight spreads (often under $1)
  • Large orders fill easily

Low Liquidity

Small altcoin:

  • Thousands in daily volume
  • Wide spreads (5%+)
  • Large orders cause slippage
