How Index binary option differs from related terms

Index binary option is often researched beside Commodity binary option and Forex binary option and Stock binary option. The labels can appear in the same workflow, but they do not describe the same field or condition.

01
Commodity binary option

A fixed-outcome contract referenced to a commodity such as gold or oil, subject to the broker's price source and trading schedule.

02
Forex binary option

A fixed-outcome contract referenced to a currency pair, with settlement determined by the broker's stated expiry and price source.

03
Stock binary option

A fixed-outcome contract referenced to a company share price rather than ownership of the underlying stock.

Practical use

Describe the event that determines the payoff

Index binary option means a fixed-outcome contract referenced to a stock-market index, subject to the broker's stated market hours and settlement source. A contract label is shorthand for an outcome condition, observation rule, expiry, and predefined payoff. Marketing names vary, so the written specification matters more than the label.
