Binaries pricing

Binaries are priced between 0-100. If the price is closer to 100 then we are pricing the event as more likely to occur, while if the price is closer to 0 then we are pricing the event as less likely to occur.

​​The outcome of a binary ie whether a specified event has occurred or not, is determined against the reference price, known as the settlement price. The settlement price is only relevant for determining whether you have won or lost a binary.

Indices

Cash

Using a blend of the underlying benchmark index price data and futures price data (adjusted for any dividends, the applicable interest rate and the time to expiry) our automated pricing engine calculates a theoretical cash price for each binary expiry (the timeframe for each binary).  The theoretical cash price along with the strike price, time to expiry, effective interest rate and our expectation of volatility are factored when calculating our binary prices. Each binary expiry is then subject to market-making (by our automated pricing engine or manually by our dealers).

Settlement prices are based on the relevant underlying benchmark index price data. (The basis of the settlement price for each binary expiry is described on the platform.)

Note: the blend (of the underlying benchmark index price data and futures price data) used in pricing calculations may be different for each binary expiry and this may also differ from the blends used to generate CFD and spread bet margin trade prices and/or Countdown opening prices. This is because binary prices need to reflect the respective short- to medium-term changes in the relationship between the underlying futures price and the underlying benchmark index price, which itself differs depending on the duration of the binary expiry.

The underlying futures price data is used by our automated pricing engine to calculate our binary prices along with the strike price, time to expiry, effective interest rate and our expectation of volatility. Each binary expiry is then subject to market-making (by our automated pricing engine or manually by our dealers).

Settlement prices are based on the relevant underlying futures price data. (The basis of the settlement price for each binary expiry is described on the platform.)

FX, Gold & Silver

Cash

Using prices sourced from several major liquidity providers to the OTC FX and bullion market (Deutsche Bank, JP Morgan, Barclays, Goldman Sachs, UBS, Citi and HSBC*) our automated pricing engine calculates aggregated prices for US dollar FX pairs  such as USD/CHF or GBP/USD, weighting them by time, mid-price and spread. All non US dollar FX crosses are generally then synthetically created from the applicable US dollar FX pairs, although in some instances may be created using the same method as that for US dollar FX pairs explained above. This price along with the strike price, time to expiry, effective interest rate and our expectation of volatility is used by our automated pricing engine to create our binary prices. Each binary expiry is then subject to market-making (by our automated pricing engine or manually by our dealers).
