Expiry controls shape the whole experience
Expiry is when the contract condition is evaluated. Short expiries make order timing, acceptance, and final price visibility more important.
Do not infer duration from turbo or short-term labels. Write down the exact expiry, such as 5 seconds (5s), 30 seconds (30s), 1 minute (1m), or 5 minutes (5m), plus when the timer starts and when the order is accepted.
Compare whether expiry is selected by timer, clock time, contract duration, or product-specific rules. Then check user reports for delayed orders, rejected orders, and unclear settlement records.
A relative countdown such as 1 minute or 5 minutes.
A fixed settlement time such as 16:30.
A scheduled macro event period where volatility can change quickly.
