Traders pay the following fees to LPs(limWETH providers and individual LP positions)
Origination Fees -> Paid when a position is opened
Lending Interest -> Paid continuously every block
Force Close Fees -> Paid when a trader fails to replenish his/her interest deposit and as a result the position is force closed
Profit Share-> Paid only when a position incurs positive PnL. This is paid by the traders due to the adverse risk the LPs are undertaking when lending out against long tail assets.
