Aquis Exchange

Aquis Exchange welcomes enquiries from firms that are interested in becoming a trading Member, connectivity provider, software vendor or market data provider.

Trading membership of Aquis Exchange is open to EEA regulated investment firms or credit institutions. Aquis Exchange may also consider unregulated firms for Membership upon provision of additional information by the applicant.



The Aquis Exchange approach to pricing is simple, fair and transparent. Similar to the telecoms industry, Members are charged according to the message traffic they generate rather than a basis point commission on the value of each stock that they trade.

Aquis Exchange has different pricing bands to accommodate varying degrees of usage. For example:

  • A very low usage band for small firms, which are traditionally disadvantaged by the pricing structures of incumbent exchanges.
  • An upper band for the largest consumers, where usage is unlimited (subject to a fair usage policy).
  • Messages relating to posted (passive) liquidity are not counted in the allowance.

Aquis Exchange does not charge any additional fees for connectivity and market data.

The complete Fee Schedule is available in the Document Library.



Members can trade on Aquis Exchange either using the industry standard FIX Protocol or the Aquis Trading Protocol (ATP).
