To calculate the Trading APR, Beefy uses on-chain data and a 24 hour period to determine the trading volume and subsequent fees, whereas most DEXes use a 7 day period. This may lead to differences in the displayed APY when compared with a DEX, but know that it is due to the calculation method. In fact, we argue that Beefy is more accurate because it uses a shorter time span which reflects changes in Trading APR sooner.
