The SIX Swiss Exchange levies a fee for all on- and off-order book transactions, which includes the reporting fee. The trading fees are of a modular structure.
They consist of a fixed transaction fee and a turnover-dependent "ad valorum" fee that is expressed in basis points and subject to an upper (cap) and lower (floor) limit. It is dependent on the specific type of execution. The fee model rewards orders that generate liquidity in the order book.
