Yield for LP positions comes from multiple sources: DEX trading fees (automatically reflected in an increasing value of LP tokens), vault rewards (if any, periodically compounded and reflected in an increasing quantity of LP tokens), and TAROT farming rewards (if any, manually claimable in the Farm tab) are all factored into the estimated APR. Trading fees are calculated based on historical DEX trading volume over the past 24 hours, and actual trading fees may differ from historical trading fees, particularly after periods of elevated trading volume. Vault rewards and farming rewards are calculated based on their current rates.
