A Uniswap v4 hook that applies dynamic LP fees based on NYSE market session schedules (2026–2050), ranging from 4.5 bps during regular hours to 74.5 bps when markets are closed. It also charges an additional 0.5 bp hook fee on each swap's unspecified amount, which is taken via PoolManager and sent to a configured fee recipient.
