Who this is for and what it solves
IEPTO serves readers checking perpetual-futures costs, liquidation rules, funding and position risk. Each page must complete a distinct task rather than create interchangeable URLs for nearby search phrases.
How evidence is graded
Material conclusions use the strongest source a reader can trace, while published rules, IEPTO observations, editorial interpretation and real-account experience remain distinct.
- First-hand evidence: account captures, transaction records or reproducible test logs with sensitive fields removed.
- Public primary sources: regulator material, venue contract rules, fee schedules, API documentation and responses.
- IEPTO observation: stored data naming the venue, instrument, timestamp and collection method.
- Pending: KYC, transfers, execution, support and regional availability receive no score or winner claim without a current real-account record.
How calculations are validated
Calculators disclose inputs, formula assumptions, tier units, fee scope and exclusions; venue-specific models remain separate. Boundary and regression tests check outputs, but the venue account and order preview remain authoritative.
How automation and AI are used
Automation collects public data and checks staleness, localization, links and structured data. AI may assist drafting, translation and QA. Volatile facts are still checked against a current primary source, and no account experience or conclusion is generated without evidence.
Updates, dates and corrections
An article date changes only after a factual, methodological or substantive edit. Data pages show collection or settlement time; rules that can change retain a source and checked date. Errors are corrected in the copy and tests rather than hidden behind a fresh date.
Affiliate links do not determine rank
Some venue links are disclosed affiliate links. Commission cannot change calculations, table order, evidence status or editorial conclusions. No venue is labelled cheapest or best without a like-for-like calculation or comparable evidence.
Data use terms
Funding rates, maintenance-margin tiers, instrument listings and open-interest figures are collected from each exchange's public API. That source data belongs to the respective exchange and remains subject to its own terms; IEPTO grants no licence to it.
- IEPTO's derived figures — annualised funding, cross-venue spreads, liquidation distances by tier and listing timelines — may be quoted or cited with attribution to IEPTO and a link to the page used.
- Bulk scraping, systematic copying of tables, or republishing the data as a feed or product requires prior written permission. All other rights are reserved.
- Figures are observations and model outputs, not trading advice; the exchange account and order preview remain authoritative.
