Documentation
Liquidity providers to the Surge pool earn from traders P/L, fees, and funding. This is typically measured in APY (Annual Percentage Yield) or APR (Annual Percentage Rate).
The charts provided show the history of the APR earned (or paid) by liquidity providers.
The APR is shown on the chart instead of the APY given the high volatility that results in astronomically high percentages if compounded using APY.
APY values are provided below the chart in "Liq. Provider APY".
