FFAJ rules for member firms set a minimum two-hour period from trading start to judgement time for retail OTC currency binaries. They also generally space judgement times at least two hours apart. The primary record is Financial Futures Association of Japan: Rules for OTC binary options. It fixes the date, unit and scope behind the claim; the interpretation below is editorial analysis, not a market forecast or trading instruction.

This rule gives a useful jurisdiction-specific counterpoint to the short-expiry formats often seen online. The relevant distinction is that these are FFAJ member rules for Japanese retail OTC currency products, not a universal definition of all binary options. Product design, strike setting and judgement frequency shape the information window available to customers and can affect how a payoff is understood. A binary contract compresses an event into two outcomes, but the underlying question can still be complicated. Election rules may involve recounts, sports data may be corrected, and time-based currency products depend on the strike and judgement clock. These details affect settlement and make the document’s precise wording more useful than the headline or a displayed percentage.

The association’s page is a summary of member rules and explicitly describes some provisions as applying for the time being. It should not be generalized to all Japanese firms, overseas providers or other asset classes without checking applicable law and membership status. A two-hour minimum does not make a product risk-free or guarantee fair execution. A listing or certification record does not prove liquidity, regulator endorsement, a correct forecast or suitability for a retail customer. Jurisdictional product restrictions remain separate from a contract’s exchange status. Historical loss statistics apply only to the population and period reported by the regulator, not automatically to every current product or trader. A customer should verify the provider’s Japanese registration and association status, then read the contract terms for strike-setting time, judgement time, early exit and payout. If a platform advertises one-minute FX binaries to Japanese retail users, compare that claim with official local rules and seek confirmation from the regulator or association. Keep product availability separate from rule compliance. Before describing a product as active, confirm its current record and rulebook. Then verify the event against the official source identified by the contract. Keep fees, payout convention and settlement timing visible; a price-derived probability is not an official statistic. If local restrictions apply, state them before discussing access or product mechanics.
What the official source confirms
The Financial Futures Association of Japan says member firms’ retail OTC currency binary options must set the strike at least two hours before the judgement time, and the minimum period from trade opening to judgement is two hours. It generally requires judgement times at least two hours apart and caps them at 12 per business day. Financial Futures Association of Japan: Rules for OTC binary options
With a yes-or-no payoff, the exact event definition controls the result. Check the named market, threshold, cutoff, official settlement source, treatment of ties or delays and the maximum amount at risk. A registry label is only a summary; it cannot replace the contract specification or establish that a platform is available in a particular country.
