The pricing model Saxo Bank uses is similar to the one we apply to Vanilla Options (based on Black-Sholes model). Spreads are variable depending on maturity and currency cross.
The pricing displayed on your trading platforms is dynamic bid/ask spreads, quoted as a percentage of the potential payout, reflecting the market's expectation of the probability that the spot rate will reach (or not reach) the trigger (or barrier) level prior to expiry.
Touch Options are traded on live streaming prices from 100 up to 25,000 units of base currency of potential Payout. Other amounts are available on an RFQ basis. This will generate a two-way live quote in your platform.
There is no minimum ticket fee or commission associated with trading FX Touch Options with Saxo Bank.
