Parameters

Each reserve in a pool has these parameters that balance the supply & demand of the pool or govern the size of the loan you can take out (based on the quality and liquidity of the collateral asset).

The critical thing to remember is the borrow APR changes based on utilization. Utilization is Tokens Borrowed / Tokens Supplied. At 0% utilization, there is excess supply and no demand, while at 100% there is excess demand but no supply.
