Shark Fin products float within a certain range.
1. If the observed price is always within the price range, then:
APR = min APR + (settlement price – lower range price) ÷ (upper range price – lower range price) × (max APR – min APR).
Income = subscription amount × APR ÷ 365 × investment period.
2. If the observed price of the target falls outside of the price range, the product will be settled according to the base APR.
Income = subscription amount × default APR ÷ 365 × investment period.
