Data sources and freshness

Sources we prioritize

DZPTO uses official fee schedules, contract specifications and public exchange APIs first; when they cannot be reached, it shows the most recent record, clearly labelled. Third-party articles and search snippets are never the only 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 exchange-specific rather than applying one exchange's logic to another.

How to read update times

A displayed time is when the figure was recorded, not a promise that the exchange will keep the rate unchanged. When data is missing, out of date or unavailable, the page says clearly that reference rates are in use.

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

Data quality checks

Every rate used in a comparison carries its exchange, product, unit, conditions, source and time. Exchanges are compared only when the trade conditions match.

• 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 exchange data; a DZPTO estimate must not override live account information.
