Sources, market data & editorial methodology

Market data

The market explorer reads Aster’s public Futures V3 ticker, premium-index, funding-configuration and exchange-information endpoints through our server. Records must describe active perpetual instruments and contain usable prices, volume and source timestamps. Missing funding or interval fields remain unavailable.

Shared results are cached for approximately 60 seconds. On an upstream failure, a previously cached result may be shown for up to 15 minutes with a stale label. We mark data stale when a displayed source timestamp or the fetch timestamp is more than five minutes old. Refreshing does not guarantee newer exchange data. If there is no usable response, the table shows an unavailable state.

Quote volume is in the symbol’s quote asset. USDT and USD1 amounts are not silently added into a claimed USD total. Funding rates use the API’s lastFundingRate field and the reported interval; they are not guaranteed future settlements. Watchlists stay in local browser storage and do not synchronize across devices.

Calculations

Each tool publishes its formula, inputs and exclusions. Share links include scenario inputs in the URL; anyone with the link can read them. No calculator requests your account data. Position-size calculations budget a planned stop and are not venue-exact liquidation estimates.

Sources and freshness

We prefer official documentation, current terms and public API responses. Guides carry a review date and source links. Fees, referral terms, restrictions and mechanics are scheduled for monthly editorial review; our build checks reject a release when those records exceed the review window. A review date records a check, not a guarantee that a source has remained unchanged.

Corrections

When a discrepancy is identified, compare it with the current primary source, correct or remove the unsupported claim, and update the review date and release notes. Until resolved, official account terms and current exchange information take precedence. A public reader submission channel has not yet been established; this site does not present an unmonitored contact form.

Commercial independence

Referral actions carry a visible compensation disclosure. Eligibility information has no signup CTA. We do not sell placement in the ecosystem directory or present its inclusion as an endorsement.
