Data sources and freshness

Sources we prioritize

DZPTO prioritizes official fee schedules, contract specifications, and public exchange interfaces, followed by clearly labeled local cache records. Third-party articles and search snippets are not the sole basis for a fee conclusion.

• Fees: distinguish spot, derivatives, maker, taker, and account tier.
• Funding: preserve the market, value, observation time, and settlement conditions.
• Contract rules: keep models venue-specific rather than applying one venue's logic to another.

How to read update times

A displayed time is the record timestamp, not a promise that the venue will keep the rate unchanged. When data is missing, stale, or unavailable, the interface should clearly identify sample or fallback data.

Recheck the venue's official page at the moment you register, place an order, or transfer assets.

Data quality checks

Before a record enters a comparison, it should identify the venue, product, unit, conditions, source, and observation time. Venues are ordered only after the trade conditions are aligned.

• Affiliate commission does not alter data, costs, or ranking.
• Uncompleted account testing is never described as firsthand experience.
• When sources conflict, the limitation is retained instead of filling the gap with a guess.

When your account shows something different

First check that the market, contract type, order type, account tier, and timestamp match. If they do and a difference remains, use the venue data; a DZPTO estimate must not override live account information.
