Saxo is 2-wide on EURUSD spot. They're 16-wide on EURUSD straddles. Globex is <10-wide on atm straddles. You need to give-up some edge for OTC-terms. Saxo's spreads are fixed for itm/atm/otm, which is absurd. Obviously it's best to trade atm positions if dealing with Saxo. Saxo will be offering a variety of American and European exotics this month; touches, DNTs, barriers; KI/KO and doubles. However, no lookbacks on the platform.
