Price Sources and Result Evidence

View as Markdown

All three prediction games use the platform’s perpetual-contract mark price for their price basis. A last trade, an external exchange quote, or a browser chart can differ from that mark price.

Evidence by game

GameRelevant evidence
Up/DownRound opening price, settlement price, and scheduled timestamps
CustomThe order’s opening price, expiry, and settlement price
GridThe accepted interval, valid time window, and price path during that window

Why a screenshot may differ

A display can be delayed, rounded, sampled at a different interval, or show another price type. Compare the symbol, price source, timestamp, and precision before concluding that a result is wrong.

For grid orders, the final price alone cannot prove whether an earlier touch occurred. The valid-window price evidence matters, including a crossing between observed prices under the game’s rule.

Time and boundaries

Use the timestamps stored with the order. A device clock or countdown is an aid for display, not the authority for accepting a late order or changing its window. Boundary inclusion and price precision must match the applicable product rules.

When data is abnormal

Keep the order number and the affected time window, then check the order’s processing status. Do not substitute another exchange’s price to settle a disputed order yourself. See Refunds and Exceptions.
