# Can you explain the concept of <\<Bins>> on ION Finance?

On ION Finance, a **<\<Bin>>** 🗑 represents a mini-market within the order book, where each bin has a fixed exchange rate between two assets. These bins collectively facilitate the trading of token pairs at different prices. An active bin is where the current trading occurs, and as trades are executed, liquidity can move from one bin to another to complete transactions.
